1-3 LDZ1 FRONT PANEL INDICATORS

1-3.1 Leak Detected LED This red LED will flash quickly if a leak is detected in the zone. It will flash slowly if the leak goes away before the system is reset. The LED will be on solid once the alarm is acknowledged - the Quiet/Reset/Test button is pushed. If an internal Fault/Failure is detected, this LED will come on solid for 5 seconds and flash on and off at a 1/2 second rate.

1-3.2 Cable Fault LED This yellow LED will flashes quickly if a cable fault is detected in the zone. It will flash slowly once the fault clears. The LED will be on solid once the alarm is acknowledged - the Quiet/Reset/Test button is pushed. If an internal Fault/Failure is detected, this LED will come on solid for 5 seconds and flash on and off at a 1/2 second rate.

1-3.3 Power LED On (green) as long as power is on.

1-3.4 Audible Alarm Activates when a leak or cable fault is detected. The Audible Alarm can be silenced with the Quiet/Reset/Test switch.

1-3.5 Quiet/Reset/Test Switch: Quiet - Press the switch momentarily to silence the audible alarm, any LED(s) in alarm will glow solidly. If the alarm goes away, the LED(s) will flash slowly. Reset - If an alarm is not present, press the switch momentarily to reset the system. If the audible alarm has been silenced (See Quiet) a second momentary depression of the switch will perform a system reset. If any alarms still exist after they are reset, the LEDs will turn on, the audible alarm will sound, and the relays will activate. If an internal fault/failure condition exists (See Leak Detected and Cable Fault LED), press the switch continuously for two seconds to reset the system. If the internal fault/failure is still present, it will return as a new alarm. Test Switch - Pressing the switch continuously for one second will light the Fault LED and then the Leak LED in sequence and the audible alarm will sound. If the switch is held for the entire test sequence, the LEDs will glow solidly and both relays will activate until the switch is released. This test sequence will also cycle when the unit is powered on.

CHAPTER 2: INSTALLATION

2-1 BEFORE YOU BEGIN 1. Remove the front cover from the LDZ1/LDZ1-NA by removing the four screws from the front of the

unit. 2. Inspect the unit to make sure no damage has occurred through shipping.

2-2 INSTALLATION INSTRUCTIONS 1. Select a location for the LDZ1/LDZ1-NA and place the two screw anchors in the wall 4.25”

(107.95mm) apart (See drawing “LDZ1/LDZ1-NA Wall Mount). Screw both screws into the wall anchors so that approximately 1/8” of each screw is showing (You may need to adjust the screws – in or out – so that the unit fits snugly to the wall). Hang the unit on the screws. Pull the unit toward the ground, so the screws nestle in the top of each keyhole and securely fasten the unit to the wall.

Figure 2-1: LDZ1 / LDZ1-NA Wall Mount

2. Adjust R25, the Leak Sensitivity, to the desired setting (High to Low). The Factory setting is the

center position (Approx. 150uA – mid sensitivity). See the “Leak Sensitivity Setting, Relay and Alarm Response Time Configuration” section on page 9.

Warning! Be sure to connect this circuit properly. The unit can be damaged if it is miswired.

User Guide: LDZ1/LDZ1-NA Chapter 2: Installation


3. Make the connection(s) to the Relay’s terminal block through the appropriate knock out (use hardware

supplied or conduit) and configure the Relay per the “Leak Sensitivity Setting, Relay and Alarm Response Time Configuration” section on page 9.

4. Make the proper wiring connections to the internal terminal block through the knock outs provided for

the LDZ1 or LDZ1-NA and provide 24VAC or DC power (See the “Terminal Block Designation” section on page 5).

5. Remove the LDZ1/LDZ1-NA from the wall and place the front cover back onto the LDZ1/LDZ1-NA

with the four screws removed in step 1.

NOTE • If the product is being used with a customer provided power supply

for the DC input, the supply must be isolated. An isolated supply means there

is no physical connection to earth or chassis ground. Failure to use an isolated power supply could cause false alarms and/or degrade system

performance. If you do not have an isolated power supply available, contact RLE Technologies.

Chapter 3: Testing User Guide: LDZ1/LDZ1-NA


CHAPTER 3: TESTING

3-1 LDZ1 TESTING 1. Ensure that the proper electrical connections have been made.

2. Turn on the power to the unit. Depress the Quiet/Reset/Test switch on the LDZ1. Make sure the alarm

LEDs light and the Sonalert sounds.

3. Remove the “End of Line Terminator” connector from the end of the sensing cable run. The Fault LED should flash at a one second rate and the Fault Relay contacts should transfer (TB1-6, 7 and 8). Reconnect the “End of Line Terminator” to the end of the sensing cable run. Wait 30 seconds. The Fault LED should flash at a slow rate (1/2 second on, 2 seconds off). Press the Quiet/Reset/Test pushbutton. The Fault LED should turn off and the Fault Relay output should return to normal.

4. Use a damp cloth/sponge or pour water on the sense cable (anywhere along the length). The Leak

LED should flash at a one second rate and the Leak Relay contacts should transfer (TB1-3, 4 and 5). Dry off the cable (remove from water and/or dry with a cloth). Wait 30 seconds. The Leak LED should flash at a slow rate (1/2 second on, 2 seconds off). Press the Quiet/Reset/Test pushbutton. The Leak LED should turn off and the Leak Relay output should return to normal.

3-2 LDZ1-NA TESTING 1. Ensure that the proper electrical connections have been made. 2. Turn on the power to the unit. Make sure the Status LED lights (on solid). 3. Remove the “End of Line Terminator” connector from the end of the sensing cable run. Wait 10

seconds or 2 minutes (depends in SW1-4 setting see configuration section on page 9.) The Status LED should flash at a four second rate with two flashes ( ½ second on, ½ second off, ½ second on) followed by a 2 ½ second pause (off) and the Summary Alarm Relay contacts should transfer (TB1-3, 4 and 5). Reconnect the “End of Line Terminator” to the end of the sensing cable run. Wait 30 seconds. The Status LED should turn on solid and the Summary Alarm Relay output should return to normal.

4. Use a damp cloth/sponge or pour water on the sense cable (anywhere along the length). The Status

LED should flash at a one second rate ( ½ second on, ½ second off) and the Summary Alarm Relay contacts should transfer (TB1-3, 4 and 5). Dry off the cable (remove from water and/or dry with a cloth). Wait 30 seconds. The Status LED should turn on solid and the Summary Alarm Relay output should return to normal.

User Guide: LDZ1/LDZ1-NA Chapter 4: Maintenance and Configuration


CHAPTER 4: MAINTENANCE AND CONFIGURATION

4-1 LDZ1 AND LDZ1-NA MAINTENANCE The LDZ1/LDZ1-NA should be tested on a monthly basis by one of the following methods:

1. Depress the local test switch (LDZ1 only).

2. Use a damp cloth/sponge or pour water on the sensing cable. The amount of water will depend on the unit’s sensitivity setting.

4-2 LEAK SENSITIVITY, RELAY AND ALARM DELAY CONFIGURATIONS

4-2.1 Leak Sensitivity To set the sensitivity of the LDZ1/LDZ1-NA, turn the Sensitivity dial (R25) to the desired sensitivity position – High to Low. This is accomplished by turning the Sensitivity dial’s slot counterclockwise to make the LDZ1/LDZ1-NA less sensitive (Low). This means that a leak will be reported when a large amount of water is present. Turn the slot clockwise to make the LDZ1/LDZ1-NA more sensitive (High). This means that a leak will be reported when a small amount of water is present.

4-2.2 Relay Configuration (see LDZ1 & LDZ1-NA Configuration Diagrams on page 9)

4-2.2.1 SW1, Position 1 - Configures the output relay(s) as supervised or non-supervised. If the relays are supervised, the relays will remain “On” until either power goes away or an alarm is detected (Relay will turn “Off”). If the relays are non-supervised (normal state is “Off”), then when an alarm is detected the relays will activate (“On”).

• Off = Non-supervised (Factory default) • On = Supervised

4-2.2.2 SW1, Position 2 - Configures the relay(s) as non-latched or latched for the LDZ1 only. If the relays are latched, then when an alarm occurs, the relay will remain in its alarm state until the Quiet/Reset/Test switch is pressed. If the relays are non-latched, then the relay will remain in an alarm state (after alarm occurs) until either the Quiet/Reset/Test switch is pressed or the condition that tripped the relay goes away.

• Off = Non-latched (Factory default) • On = Latched

NOTE • This switch is “OFF” for LDZ1-NA units.

Chapter 4: Maintenance and Configuration User Guide: LDZ1/LDZ1-NA


4-2.2.3 SW1, Position 3 – configures the two output relays (LDZ1 only) as a summary alarm output (DPDT) or as separate leak and fault (trouble) relay outputs.

• Off = Leak and Fault (Trouble) Relay Outputs (Factory Default) • On = Summary Alarm Outputs

4-2.3 Alarm Delay Configuration

4-2.3.1 SW1, Position 4 – Configures the Alarm Delay. This is the response time or the time it takes for the device to report/annunciate an alarm condition (leak or fault) once sensed. The alarm must be present during this period. The Alarm Delay me can be set to 10 seconds or 2 minutes.

• Off = 10 seconds (Factory Default) • On = 2 minutes

Figure 4-1: Dip Switch For LDZ1 Only (Off for LDZ1-NA)

NOTE • This switch is “OFF” for LDZ1-NA units.

Appendix A: Troubleshooting User Guide: LDZ1/LDZ1-NA


APPENDIX A: TROUBLESHOOTING Trouble Action

No Power Power ON LED (LDZ1) is not On Status LED (LDZ1-NA) is not On

Check Power Supply For AC Input: Check for supply power on TB1 pins 1 and 2

1) If power is not present at TB1 pins 1 and 2, check AC input voltage to

wall adapter, if used.

2) If voltage (power)is present at TB1, please contact RLE Technologies. For DC Input: Check for supply power on TB2 pins 1 and 2.

1) If power is not present at TB2 pins 1 and 2, check the DC voltage at the

DC supply source/distribution panel.

2) If voltage (power) is present at TB2, please contact RLE Technologies.

Cable Fault

Check and make sure Leader Cable Connector is attached to P1 on the LDZ1/LDZ1-NA PC Board. The Wiring order should be as follows from left to right: White, Black, Green and Red.

1) If wiring order is correct and the leader cable is attached to P1,

disconnect the End-of-Line terminator from the end of the orange sense cable. Then connect the End- of-Line terminator to the end of the leader cable (non-sensing). For an LDZ1 push the Quiet/Reset/Test Push button to reset the system once connected. The LDZ1-NA will reset within 30 seconds.

2) If the cable fault condition goes away, there is either a faulty or

damaged section of orange cable (sense) or the product is being powered with a customer provided power supply for the DC input that is NOT isolated. An isolated supply means there is no physical connection to earth or chassis ground. Failure to use an isolated power supply could cause false alarms and/or degrade system performance.

3) If the fault condition does not clear, remove the Leader Cable connector

from P1 on the PC Board and place a jumper or create a short between pins 1 and 2, and another jumper or short between pins 3 and 4.

4) If the condition still exists, please contact RLE Technologies for extra support. If the condition clears, the leader cable is faulty (open wire(s).

Leak Detected

Check and make sure there is no water present on or around the zone in alarm.

1) If water is present, dry affected area and wait for the alarm to reset for

an LDZ1-NA or press the Quiet/Reset/Test pushbutton on the LDZ1 to reset the unit. If the condition does not clear, follow step (2).

User Guide: LDZ1/LDZ1-NA Appendix A: Troubleshooting


2) Remove the End-of-Line terminator from the end of the orange sense

cable and install it onto the end of the leader cable. If the condition clears, there is a water leak, damage to the sense cable or the product is being powered with a customer provided power supply for the DC input that is NOT isolated. An isolated supply means there is no physical connection to earth or chassis ground. Failure to use an isolated power supply could cause false alarms and/or degrade system performance. Start moving the End-of-Line terminator to the end of each cable section until the water-detected fault reoccurs. If the condition is still present once the End-of-Line terminator has been placed on the end of the leader cable, follow step (3).

3) Disconnect the Leader Cable from the P1 connector on the

LDZ1/LDZ1-NA PC board. Place a jumper or create a short between pins 1 and 2, and another jumper or short between pins 3 and 4. If the condition is corrected, there is a problem with the leader cable. If the water leak condition is still present, contact RLE Technologies for support.

Internal Fault/Failure Alarm

Reset the system by pressing the Quiet/Reset/Test pushbutton for two seconds for the LDZ1 and/or cycle power. If the alarm still exits after trying to reset the system (Cycle power, etc.), contact RLE Technologies for support.
