SECURITRON MODEL EXD EXIT DELAY SYSTEMS INSTALLATION AND OPERATING INSTRUCTIONS

1. DESCRIPTION

Securitron’s EXD series is modular delayed exit locking systems intended for use on emergency exit doors. The systems fully meet American and Canadian building codes for delayed exit (Special Locking Arrangements). Configurations within the series are appropriate for fire rated and non-fire rated doors. Briefly, all EXD systems function as follows: The door's normal condition is secure from an electromagnetic lock. A person desiring to exit employs an exit bar or similar delay initiating device which starts an irreversible delay of 15 or 30 seconds. During this release delay period, a local Sonalert sounds and a remote alarm signal also activates. At the end of the delay, the local Sonalert stops and the lock releases. It remains released until manually reset (relocked). In some code versions, reset is accomplished by a momentary turn of a keyswitch mounted at the door. Other code versions mandate the use of a doorswitch so that reset is accomplished by the act of opening the door. See Section 4 for a detailed discussion of the different code requirements. The modular nature of the systems allows great flexibility in that the user can select individual components within the system structure. This permits creating a configuration that optimally suits the application requirements. EXD systems also support optional functions that can be employed in entry control, door/lock monitoring, and authorized immediate exit. External switches such as time clocks can also put the system into different modes if delayed exit is not desired at all times. 2. SYSTEM COMPONENTS The following sections discuss the individual components which go to make up an EXD system under UL and ULC listings.

PN# 500-13350 Page 2 Rev. E, 11/11

2.1 LOCKING DEVICE The full range of Securitron's model 62, 68, 82, 32, 38 and model SAM shear aligning series electromagnetic locks is available as part of an EXD system. The model 62, 68 (1200 lbs.) or model 82 (1800 lbs.) is appropriate for applications requiring high physical security. The model 32, 38 (600 lbs.) is for applications requiring "traffic control" security levels. The SAM is used when a fully concealed installation is desired or in specialty applications where the door must swing both ways. Selection is made first according to whether the door swings out or in (standard or "F" version). Note however that the SAM does not include a door swing direction variable. Adding “B” to the part number adds lock status sensing with an SPDT output. If lock status sensing is selected, note that the logic timer component of any EXD system includes lock status monitoring. 2.2 DELAY INITIATING DEVICE 2.2.1 WHEN INTEGRATED WITH ACCESS CONTROL The initiate device opens a switch to electronically trigger the delay cycle. A broad selection of initiate devices are available for use with the EXD system.

Available devices include Securitron's range of Touch Sense Bars (TSB-3 series). The Touch Sense Bar is available in two finishes (clear anodized and black anodized) and in 3 lengths to correspond to standard door opening widths (36", 42" and 48"). The Touch Sense Bar electronically detects skin proximity (even through clothing) and as such, suffers no wear with repeated use. It also has a redundant circuit backup

switch which provides extra reliability in the event of any electronic failure. A similar device is Securitron’s Touch Sense Handle (TSH series). The Touch Sense Handle is electronically identical to the Touch Sense Bar and also comes in clear or black anodized finish. The handle can be employed to push a door open (normal use) or pull a door open in a specialty situation where the exit door doesn’t open outwards (this use should be confirmed with your local fire or building inspector). Also, depending on the building occupancy type, an exit bar rather than exit handle may be required by code. Again consult your local building or fire department. Another specialty application mentioned earlier is when the SAM (shear aligning Magnalock is employed on a double acting door (which swings both ways). In this instance, the TSH is an interesting initiate device as it can conveniently propel the door in either direction. Both the Touch Sense Bar and Handle are intended for use on Non-fire rated doors (fire rated doors must be positively latched by fire rated latching hardware). For fire rated doors where electronic access is included in the system requirements, you should employ a switch equipped fire rated mechanical panic bar with free moving entry trim on the outside of the door. When the bar is depressed from the inside, the integral switch opens which initiates the release delay. At the same time, the latch is withdrawn which permits exit once the delay has expired. For entry, once the Magnalock has been released (by the card reader for example) the trim handle is turned from the outside which retracts the latch and permits non alarmed entry. Turning the trim handle from the outside however does not activate the initiate switch within the panic bar so delay cannot be initiated from the outside. Certain fire rated, switch equipped panic bars manufactured by firms other than Securitron have been tested as part of this system (consult current label data). Fire rated switch equipped panic bars from still other manufacturers can be considered for use with the EXD system if the local authorities understand and accept that these bars have not been individually tested with the EXD system. 2.2.2 INITIATE DEVICES FOR EGRESS CONTROL ONLY The principal advantage of the initiate devices discussed in this section is that existing latching door hardware (fire or non-fire rated) does not have to be removed. This results in considerable savings in installation costs. Note that the initiate devices discussed in this section require the presence of latching exit hardware.

PN# 500-13350 Page 3 Rev. E, 11/11

The MXD is a kit which includes a housing that surrounds the magnet body and conceals a proximity switch array. Note: it is not compatible with the SAM shear aligning Magnalock. A permanent magnet array is also part of the kit and this mounts behind the strike plate so that a signal is generated when the door is partially opened (the distance between the permanent magnet array on the door and the proximity switch array within the magnet housing increases to a detection point). The door is allowed to open a distance of about one inch by the presence in the kit of a spring loaded sex bolt which has an internal plunger that telescopes out when an attempt is made to open the door. A person desiring to exit clears the latch by activating the exit hardware and then moves

the door open approximately an inch at which point all the slack in the special sex bolt is taken up. This movement is detected and the initiate signal is provided. The SB-MXD (also not compatible with the SAM) operates the same way but the housing for the magnet body is eliminated as is the permanent magnet array behind the strike plate. Instead, the limited door movement permitted by the spring loaded sex bolt is detected by a furnished, separately mounted magnetic door switch. This permits a more compact installation but is less tamper proof.

Finally, where the latching exit hardware is of the mortise type (rather than rim or vertical rod), Securitron’s LM series of Latch Monitors may be used (assuming wires can be pulled up the door frame). The Latch Monitor mounts behind the strike of the mechanical exit hardware latch and detects when the latch is withdrawn by the exit hardware. Withdrawal of the latch initiates the delay. Compared to the MXD, the Latch Monitor is much less tamper resistant but yields a very compact and low cost installation. Note that electronic access control cannot be integrated with the initiate devices in this section because we can’t allow the latch to be retracted from the outside to permit entry. If latch retraction from the outside was possible, the delay could be initiated from the outside for unauthorized entry and this defeats the purpose of the system.

2.3 LOGIC TIMER All logic and timing functions for the EXD system are performed by a special timer (Model XDT-12 or XDT-24) implemented on a circuit board. The board is supplied from Securitron in a locking surface mount enclosure which includes a Sonalert on its cover. The part number for the complete assembly (board + enclosure) is BA-XDT-12 or BA-XDT-24. Alternately Securitron offers a flush mount enclosure (FA-XDT-12 or FA-XDT-24). The XDT timer is a powerful microprocessor device which not only performs the logic functions necessary to meet the different codes, but provides many optional features that enhance the security and safety aspects of the installation. See Section 7 for the details of optional functions. 2.4 RESET DEVICE Once the door has been released, it will remain in this state until "manually" reset. In the EXD system, this is accomplished by a normally closed switch opening then closing once more (momentary action). The switch is supplied as part of Securitron's MK series mortise keyswitch which is mounted at the door so that the door will be inspected by a responsible individual prior to reset. The MK requires the on site addition of a 1 1/4" or 1 1/8" mortise cylinder which activates the switch. Typically, the cylinder is furnished by a local locksmith and is keyed into the facility keying system. The standard MK is furnished on a single gang outlet box cover. The MKN version is furnished on a 1 3/4" plate for narrow style door frames. A red/green bicolor LED is included.

PN# 500-13350 Page 4 Rev. E, 11/11

Certain code versions require the use of a door switch to accomplish reset. You may select any door switch (switch should be closed when the door is closed) with minimum electrical ratings of 30 VDC and 250 mA as an alternate part of this system. 2.5 POWER SUPPLY The EXD systems must operate on 12 or 24 VDC power. Securitron supplies a range of power supplies (BPS series) to meet this requirement as part of the system. Selection of the power supply depends first on whether 12 or 24 volts is preferred for the installation. Next, the capacity of the power supply is selected according to how many doors are installed. Although individual supplies could be installed for each door, an EXD system according to code includes a central break from the fire alarm system so, since wires need to be run from a central point to each door anyway, it is most cost effective to use one power supply to operate all the doors. 12 Volt power supplies in the BPS series range from 1-15 Amps in output capacity. 24 Volt supplies range from 1-10 Amps. Battery backup may be supplied as an option (see Section 6.2.4). 3. DETAILED DELAYED EXIT FUNCTIONS Exact code requirements for delayed exit vary somewhat in different jurisdictions. These detailed variations will be addressed in Section 4. In general, however, delayed exit includes the following components and sequences of operation. In the normal condition, the door is locked. The initiate device is used to start the exit sequence. Once the initiate switch opens, a nuisance delay period begins. The nuisance delay period may be set for 1, 2 or 3 seconds. The duration of the nuisance delay period will depend on the local code and/or on the desires of the end user. The nuisance delay function can also be disabled. During the nuisance delay period, the XDT logic timer provides a pulsing relay output which is used to operate a local Sonalert. This notifies the person at the door that he has activated the initiate device. If he intends to exit, he must maintain pressure on the exit device until the end of the nuisance delay period. If he releases the bar before the nuisance delay times out, the local alarm signal will stop and the door will revert to normal (locked) mode. Once the nuisance delay times out (or immediately if no nuisance delay has been set) the release delay period begins. The XDT's local alarm output will go from pulsing to steady. This will alert the person at the door that he need no longer maintain pressure on the exit hardware. Once the release delay begins, it is irrevocable. The door will release at the end of the period. Code mandated duration of the release delay period is 15 seconds although certain jurisdictions allow extension to 30 seconds by local building or fire safety officials. The release delay period on the XDT can therefore be set for 15 or 30 seconds and this total release delay time includes the nuisance delay. Once the door has released, it will remain released until manually relocked by a reset device. This is a normally closed switch which is momentarily activated (opened). Relocking actually occurs on reclosure of the switch. The reset device is Securitron's model MK, a momentary spring loaded keyswitch, or a door switch (where required). We recommend that the keyswitch be mounted at the door as this insures that security staff will actually inspect the door. In some jurisdictions the reset device may be a doorswitch. With a doorswitch, relocking occurs from the act of exiting the door. Certain codes require the use of a doorswitch or special timing sequences as will be discussed in Section 4. As mentioned earlier, the local alarm relay output incorporated on the board is necessary to meet the codes. This relay pulses during the nuisance delay period, energizes during the release delay period and is deenergized at all other times. For more powerful monitoring, the board includes a second alarm signal called the remote alarm relay. This relay is normally energized; it deenergizes to show an alarm condition. It signals alarm from the beginning of the release delay period until the door is relocked. The remote alarm relay is intended to signal to a security office that a security violation is occurring at the door. It ignores the nuisance delay period as this should be seen as a "false alarm" unless the delay becomes irrevocable. It also continues to signal until the door is relocked, correcting the security violation. The remote alarm relay should also be considered a general "trouble" signal. If the board loses power, this relay will de-energize signaling trouble. It is also used to signal other optional alarm conditions described in Section 7.

4. SPECIFIC CODE REQUIREMENTS We must strongly emphasize that the following sections on code requirements should not be considered definitive. They represent Securitron's best understanding of the individual codes at the time of this manual's most recent revision. Codes, however, can change suddenly and are also subject to local interpretations that may differ from the descriptions that follow. You should consider these descriptions as a starting point which should be confirmed or altered by the local authority having jurisdiction. Also, many customers are interested in the issue of UL testing for systems of this type. EXD systems are UL listed under the UL FWAX category which is also called Special Locking Arrangements. UL tests all systems applying for such a listing under a test standard which presently only recognizes the method of operation detailed in the NFPA 101 code for Special Locking Arrangements. This is a limitation of the UL test standards. In many parts of the United States, however, operational requirements as set by the authority having jurisdiction will vary in minor ways from the exact requirements of NFPA 101. The EXD system has been designed to be able to perform these alterations in operating sequence so that it can meet differing operating requirements as set by the different model codes. UL, however, has tested only operation under NFPA 101 and therefore takes no position on the ability of the EXD system to meet alternate code requirements. The EXD's ability to do this is warranteed by Securitron. In the following 5 sections, we describe individual code requirements in 4 areas: Nuisance delay, Release delay, Relocking and Power. The main issue in the Power function is whether battery backup can be applied to the locking system to keep the door functional in a power failure. 4.1 NFPA 101 (SPECIAL LOCKING ARRANGEMENTS) This code by the National Fire Protective Association was the first implementation of delayed exit. It formed the basis for the different model code versions which follow and is still used in many specifications.

NUISANCE DELAY: Permitted up to 3 seconds.

RELEASE DELAY: 15 seconds or extension to 30 seconds with local approval.

RELOCKING: Must be "manual". This is generally interpreted to mean that a doorswitch can not be used for relocking. A keyswitch is the typical technique used.

POWER: The door must release when DC power to it is cut off. This means that battery backup of the system power supply may be acceptable, but this is a point to confirm with the local authority.

PN# 500-13350 Page 6 Rev. E, 11/11

4.2 STANDARD BUILDING CODE NUISANCE DELAY: Not allowed.

RELEASE DELAY: 15 seconds or extension to 30 seconds with local approval.

RELOCKING: Must occur only when the door opens. A doorswitch rather than a keyswitch must be used.

POWER: The door must release when DC power to it is cut off. This means that battery backup of the system power supply may be acceptable, but this is a point to confirm with local authority. 4.3. UNIFORM BUILDING CODE NUISANCE DELAY: Required and must be set at 2 seconds.

RELEASE DELAY: 15 seconds only.

RELOCKING: Must be "manual" and must be located at the door. This is generally interpreted to mean that a doorswitch can not be used for relocking. A keyswitch is the typical technique used.

POWER: The door must release when power to it is cut off. The door must also release if power to the smoke detection system or exit illumination system is lost. This is generally accomplished by using the same line voltage source to operate the lock power supply as operates the smoke detection and exit illumination systems. Battery backup for the locks is normally excluded. 4.4 BOCA NUISANCE DELAY: Required and must be set at 1 second.

RELEASE DELAY: 15 seconds or extension to 30 seconds with local approval.

RELOCKING: A doorswitch must be used and a special type of timed relocking is required. After the release delay expires, the lock releases. When the door is opened, the doorswitch changes state but nothing happens immediately (the lock remains released). When the door recloses, a "relock delay" of 30 seconds begins. If the door is not opened again during this 30 second period, it will relock. If it is opened again, the 30 second relock delay will begin again on door closure. The door will only relock when it has been left undisturbed for 30 seconds after reclosure. The local authority may extend the relock delay to 45 seconds for sensitive facilities. The standard XDT board supports the BOCA 30 second relock sequence. If the 45 second relock sequence is required, contact the factory to receive a modified board.

POWER: The door must release when power to it or to the building is cut off. Battery backup of the lock power supply is therefore specifically excluded. 4.5 NATIONAL BUILDING CODE OF CANADA NUISANCE DELAY: Not allowed.

RELEASE DELAY: 15 seconds only.

RELOCKING: Must be "manual". This is generally interpreted to mean that a doorswitch can not be used for relocking. A keyswitch is the typical technique used.

POWER: The door must release when power to it or to the building is cut off. Battery backup of the lock power supply is therefore specifically excluded. 5. DIP SWITCH SETTING Once you have determined the values to be set for nuisance delay, release delay and whether you want BOCA relocking used, dip switches on the XDT timer board may be set to select these parameters. The factory set condition of the board is nuisance delay disabled, 15 second release delay and standard (non BOCA) relocking. If you require a variation from this configuration, some Dip Switch settings will have to be altered.

PN# 500-13350 Page 7 Rev. E, 11/11

Switch 1: This sets the amount of time for release delay. In the factory set (Off) position, release delay is set for 15 seconds. Turning the switch On sets a 30 second release delay. Switch 2 and 3: The combined position of the 2 switches selects 4 different values for nuisance delay. MATRIX #1: Switch 2 Off; Switch 3 Off (factory set): nuisance delay disabled MATRIX #2: Switch 2 On; Switch 3 Off: 1 second nuisance delay MATRIX #3: Switch 2 Off; Switch 3 On: 2 second nuisance delay MATRIX #4: Switch 2 On; Switch 3 On: 3 second nuisance delay Switch 4: This implements BOCA timed relocking (see Section 4.4). In the factory set (Off) position, standard relocking from a momentary reset switch is implemented. When the switch is turned On, 30 second delayed BOCA relocking is set. Under some conditions, local authorities may require a 45 second delayed BOCA relocking. The standard XDT board does not support this. Contact the factory to order a modified board with the 45 second feature.

6. INSTALLATION 6.1 PHYSICAL INSTALLATION The Magnalock and initiate device should be physically mounted on the door according to their individual instructions. If the MK keyswitch is used in this installation, its instructions explain mounting the user supplied mortise cylinder. The XDT timer is supplied in its own enclosure (Model BA-XDT or model FA-XDT), and will either surface mount above the door or flush mount next to the door. 6.2 WIRING 6.2.1 BASIC WIRING Please refer to Figure 2 which shows typical wiring for an EXD with a Touch Sense Bar or Touch Sense Handle or Figure 3 for an EXD system with switch equipped mechanical panic bar, MXD, SB-MXD or Latch Monitor. These drawings show interconnections of all system components except the power supply-fire alarm connections. Wired as shown, the systems fully meet the exit delay code requirements. Note that with respect to Figure 3, the two wires coming from the un-powered initiate device are labeled “COM” and “NC”. The circuit between these two wires opens when the initiate device is used. In the case of the MXD and SB-MXD, both devices have only two wires so confusion is impossible. The bicolor LED in the reset keyswitch is connected so that it is green in the "normal" locked condition. It illuminates red when the lock has been released following the exit delay or bypass. Therefore the LED "invites" the user to turn the key and reset the door. 6.2.2 DOUBLE DOOR WIRING A double door can be accommodated by using 2 Magnalocks and 2 initiate devices. Only a single timer and reset keyswitch are necessary. With this type of wiring, activating the device on either door releases the Magnalocks on both doors. The Magnalocks are connected in parallel (red to red; black to black). The initiate device switch contacts are connected in series. With the Touch Sense Bar or Touch Sense Handle, the connection is somewhat complicated as sensor power is connected in parallel but sensor contacts are connected in series. The small drawing to the right shows the detail of the connections. To complete the installation, follow Figure 2 for connection of the other components and, as explained above, connect the 2 Magnalocks in parallel. When one of the un-powered initiate devices

shown in Figure 3 is used, the connection is simpler. +V from the power supply connects to COM of device #1. NC of device #1 connects to COM of device #2. NC of device #2 connects to terminal IN of the timer. 6.2.3 POWER SUPPLY CONNECTIONS Figure 4 shows power supply connections for Securitron's 1 Amp units and larger supplies. Either supply must first be connected to a source of 115 VAC. 2 wires then carry DC power to the timer (see figures 2 and 3). In the case of the larger, multiple output supplies, the number of doors powered should be spread among the "P" terminals. “Medium” sized supplies employ the CCS-4 control board with four “P” terminals and the largest supplies employ the CCS-8 control board with eight “P” terminals. Each “P” terminal conducts power through a 2.5 Amp Polyswitch. This is a special type of automatic fuse. If one of the Polyswitches receives an overload, it will rapidly cut the current down to a small leakage current (about 100 mA) which will allow the rest of the doors to continue to operate. Note that each “P” output includes a slide switch and LED. The slide switch can cut DC power to its respective output and the LED monitors when the output is powered. In the event of one of the Polyswitches tripping, the associated LED will go out and there is a reset procedure. First, correct the overload condition. Next, all current must be removed from the Polyswitch for a period of 10 seconds. You do this by simply moving the associated slide switch to the “off” position. Then, return the slide switch to “on” and operation will return to normal. If you haven’t corrected the overload, naturally the Polyswitch will trip again but you must always de-power and re-power the Polyswitch to reset it. If your power supply includes a battery pack, the Polyswitch will always trip as described in the previous paragraph. If, however, you are not employing batteries and you are using a Securitron power supply larger than one Amp in capacity, a short circuit or overload may not trip an individual Polyswitch. This is because the power supply itself is internally short circuit protected for additional safety and the supply itself may completely shut down before the individual Polyswitch on the affected zone can trip. The issue of whether the power supply shuts itself off or an individual Polyswitch trips depends on the overload current. In the case of a dead short, the overload current is very high and the power supply will shut down first. An overload greater than 2.5 Amps but less than the total capacity of the supply will rather cause the zone Polyswitch to trip. The presence of a battery always trips the Polyswitch because the battery will supply high current into any short or overload once the power supply can no longer maintain its voltage. Its simple to determine whether an individual Polyswitch has tripped or whether the power supply has shut down by looking at the individual zone LED’s. One will be off in the event of an individual Polyswitch trip and they will all be off in the event of power supply shut down. To recover from power supply shut down, you have to identify and correct the overload or short circuit. This should be done by turning off each zone slide switch until you find the one that restores normal operation of the supply by correcting the overload. You should then deal with the actual cause of the overload in the downstream wiring. Note that all Securitron BPS series power supplies have stand-up fuse holders. The 1 Amp units have an “AC” line voltage fuse only. This fuse will trip if the transformer primary shorts out as it fuses the incoming 115 VAC. Larger power supplies which employ the CCS-4 or CCS-8 control boards include an “AC” fuse (see figure 4) which also protects against a transformer primary short and a “DC” fuse. The DC fuse protects the full DC output of the supply prior to it being divided through the Polyswitches to the individual “P” outputs. The DC fuse should only trip if there is a short circuit in the supply itself (downstream short circuits or overloads will trip individual Polyswitches). This could occur if the F1-H terminal block somehow contacts DC negative. If the power supply appears dead (all LED’s are out), the problems could be a blown fuse or the previously described supply shut-down. Always replace any blown fuse with the same rated fuse.

Terminal FA is a free parking terminal used only with Securitron’s Power Supply Monitor. If you are using this product, wiring with the FA terminal is shown in the PSM manual. The H terminal carries +V with the full output of the power supply. It is used for specialty applications where the full output must be directly connected to a large load. EXD systems always operate off the “P” terminals so the “H” terminal is never used. Interconnection between the fire alarm system and the power supply is a vital part of the exit delay system function. In a fire, all doors must release immediately. The EXD systems accomplish this by mandating a connection with the fire alarm that cuts off all DC power to the doors. This is the simplest and most sure way to accomplish the function. A UL listed fire alarm system must be used with latching type dry contacts designed for "auxiliary" operation. Alarm or trouble contacts may not be used. The contacts must be of sufficient capacity to switch the total DC current output of the EXD power supply selected. Figure 4 clearly shows the interconnection for the three EXD power supply types. 6.2.4 BATTERY BACKUP All EXD system power supplies (BPS series) are capable of charging batteries and therefore continuing operation if local AC power fails. Certain code versions permit use of battery backup and certain ones forbid it. See Section 4 for the details. We also recommend that if battery backup is desired, its acceptance be confirmed with the local approving authority.

To implement battery backup, it is necessary for the installer to correctly determine the proper size for the battery pack which varies with the current drawn by the complete load and the backup time desired. The power supply must also be able to charge the pack. All BPS series power supplies provide a current limited charging circuit. The reason that the charge current is limited is that otherwise a recharging battery after a power failure would take current away from the locks which must also operate during battery recharging. Charge current on standard supplies is limited to 250 mA and this amount of current is capable of charging up to a 20 Amp Hour battery pack. If a larger pack is needed, Securitron can supply a modified power supply with a larger maximum charge current. Naturally, the greater charge current means that the supply loses load operating capacity. For example, a standard supply rated at a maximum total output current of 3 Amps can only supply a maximum of 2.75 Amps to the load as 250 mA is reserved for battery recharging (up to 20 Amp Hours). If the supply is modified to provide a 1 Amp charge current, which allows an 80 Amp Hour battery pack, only 2 Amps remain to be allotted to the load. Figure 5 is a chart which allows calculation of the correct size battery pack to provide a range of backup times in concert with a range of possible total system load currents. Selection of backup time will depend on the history of power outages in the area and on the level of security required for the facility. The information in the chart is valid for 12 or 24 volts although, naturally, the battery voltage must match the power supply voltage. As a rough guide, consider a single door EXD system to draw 200 mA at 24 VDC and 400 mA at 12 VDC. For multiple door systems, the total current must either be calculated or measured with an ammeter. Be sure to carefully read all of the notes at the bottom of Figure 5. 6.2.5 HIGH ENERGY HAZARD It is often assumed that electrical installations running on low voltage are inherently safe. Low voltage installations do not pose an electric shock hazard but can pose a high energy hazard

PN# 500-13350 Page 13 Rev. E, 11/11

based on the amount of current that may be supplied into a short circuit. An individual might receive a burn from an arc or, in an extreme case, a fire might be started. The BPS series power supply that operates your EXD installation may or may not include a backup battery pack depending on local regulation and on the end user’s requirements. The addition of batteries increases the high energy hazard as the battery pack is able to supply very high current into a short circuit (much higher than the maximum output of any BPS series supply). So long as your EXD installation is correctly wired according to Figure 4, however, the Polyswitches will protect against this type of hazard. For your safety, insure that they are not bypassed. 6.3 POWER FAILURE AND POWER DROP CONSIDERATIONS A related power issue is a description of how the system behaves upon loss of power or reduction of the input voltage. It is always intended that the XDT logic timer is permanently powered except in the event that the fire alarm system removes all power from the delayed exit locking system. In the "normal" condition, the timer lock control relay (C3) and the remote alarm relay (C2) are energized. The local alarm relay (C1) is deenergized. In this condition, the Magnalock is powered (secure) and no alarms are being signaled. If the timer loses power from a broken wire for instance, the lock control relay will deenergize releasing the Magnalock. This is a safety feature. The remote alarm relay will also deenergize which will signal trouble at the door. This is a security feature. The local alarm relay will remain deenergized and therefore not signal at the door as the local alarm relay is intended to signal a delayed exit event and without power, the board is not capable of producing such an event; the Magnalock is immediately released upon loss of board power. If the system has been approved for the use of battery backup, loss of building power will not immediately alter anything at the door as the batteries will take over. If power is out for an extended period of time, however, the batteries will begin to drain and lose voltage. As an additional safety feature, the XDT timer includes a low voltage sensing circuit. The board will keep working normally as the voltage declines until it reaches roughly 70% of nominal. At that point, the XDT will automatically act as if all power was removed. The Magnalock releases and the remote alarm relay deenergizes, signaling trouble at the door. 7. OPTIONAL FUNCTIONS The following optional functions are not necessary to meet delayed exit safety codes but may be implemented as desired to increase the utility of the EXD system application. All of the optional functions are enabled by altering the wiring of the XDT logic timer board, so the following Sections all focus on the XDT.

7.1 LOCK STATUS REPORTING The LS input is for optional lock (or door) status reporting. Note that when the XDT board is delivered, the LS terminal is jumpered to the "+" terminal. In this mode, the board interprets the lock as being secure so no reporting occurs, and the board can be used for normal delayed exit.

PN# 500-13350 Page 14 Rev. E, 11/11

To implement lock status reporting, a “B” version Bondstat Magnalock should be employed. Tie the red and white wires together (this puts +V on the SPDT Senstat common wire). The green wire will then report +V to the LS terminal when the lock is secure. If the Magnalock stops reporting secure when it has not been released by the board, the remote alarm relay will switch 5 seconds later and remain switched until LS again receives +V. The purpose for the 5 second delay is to allow a door to reclose and again report secure after legitimate use. If any function of the XDT board has released the door, the LS input will be ignored until the board has relocked the door. This feature allows use of the XDT board to perform exit delay and yet also report on propped doors or forced doors. If a standard (non-Bondstat) Magnalock is being used in the installation, a door switch may be employed to largely replicate this function. The switch should be closed when the door is closed and it should input +V to terminal LS. 7.2 USE OF EXTERNAL SWITCH (BYPASS FUNCTION)

In many installations, authorized entry or exit is desired on an immediate basis without giving rise to an alarm. This does not violate the delayed exit code, as when the door is in a released state, it is completely safe. There are two possible variations of external switch use: momentary timed and alternate. "Momentary timed" means release of the door for a few seconds to allow an authorized person to enter or exit. Alternate means releasing the door for an extended period of time. The most common example of this is a situation where the door is released during working hours and put into delayed exit mode at night and during the weekends. Turning first to momentary timed release, this is often from an SPDT relay operated from a controlled entry device such as a card reader. Often a keyswitch is used for authorized entry or exit. Securitron's model MK keyswitch can be delivered with 2 switches so that when the key is turned in one direction, authorized release of the door is obtained. The other direction is used for relocking after a delayed exit event. The NC contacts of the external switch are employed to cut power to the Magnalock and the NO contact connects to terminal BP. The wiring method is illustrated in the drawing to the right. The BP terminal stands for "Bypass" and it is important to understand the use of this terminal in all external switch applications. When BP receives +V, it immediately releases the lock by deenergizing the lock control relay. It also suppresses initiation of delayed exit and all board alarm signals including the remote alarm relay signal that arises from lock status sensing (see the previous Section). This is important as during authorized entry or egress, it is undesirable to create delayed exit events or alarm signals. When +V is removed from BP, it maintains the lock release condition and alarm suppression for 5 seconds. If the external switch is momentary spring loaded, this 5 second delay arising from the use of terminal BP gives sufficient time to enter or exit. If it is a timed control relay, the time should be set for 5 seconds less than the desired time. Once the timed control relay switches back, removal of power from BP will keep the lock released for an additional 5 seconds. If the external switch has only NO contacts, the same function may be gained by switching +V into BP. The reason that the drawing shows an SPDT switch breaking power to the Magnalock and triggering BP is that this enhances reliability. If a fault were to occur with the XDT board such that the BP input didn't function, the NC contacts would still release the Magnalock. For alternate operation, a time clock is used to release the door and suppress all alarms during the day and then put the door into delayed exit mode at night. The time clock switch simply closes BP to +V for the time period during which the door is to be released. When it switches again to open the connection between BP and +V, the door will remain released for an additional 5 seconds but this will be hardly noticeable.

7.3 FREE EGRESS FUNCTION The free egress function puts the XDT logic timer in a different operating mode. When +V is switched to terminal FE by an alternate action switch, the board goes into free egress mode. In this mode, use of the exit bar, immediately releases the door for egress. When the bar is released, the door immediately relocks. Often, a time clock such as Securitron's model DT-7 is used to put the door into free egress mode during the day and exit delay mode at night. The free egress mode differs from the bypass mode as follows: When the door is bypassed, the Magnalock is released so that both entry and exit is freely possible. Also, during bypass mode, the board's alarm signaling functions are suppressed. In the free egress mode, the Magnalock remains secure so that entry is blocked, but egress without alarm signaling occurs immediately when the initiate device is pressed. If lock status monitoring is in use, the remote alarm relay will still report a door that doesn't resecure within 5 seconds after a free egress event. 7.4 LOCK POWERED AFTER RELEASE DELAY MODE (DELAY CONTROL) In ordinary delayed exit, the fail safe lock releases after the delay and remains released until the reset switch performs relocking. In facilities where a threat exists from the outside, the question arises as to security against unauthorized entry after the release delay has expired. It may be that the delayed exit cycle was initiated by mistake or as an act of vandalism. It may take some time for a guard to arrive at the door to effect relocking and there is always some risk that security procedures will fail, despite the alarm signals, and the door will be left in this released state for an extended period of time. The XDT can be set so that after the release delay expires, the fail safe lock remains engaged so long as the initiate device is not being pressed. When the initiate device is pressed, the lock immediately releases but resecures after the initiate device is no longer being pressed. This preserves security from the outside. To implement this, simply run a wire from terminal DC to terminal IN. This is the only use for terminal DC. We believe that this method of operation meets the intent of all exit delay codes but it is certainly possible that conservative safety officials might reject it, so we advise that specific approval be sought for this variation.
