DESCRIPTIONDETECT-A-FIRE units are the "heart" of many FireProtection Systems. These highly reliable devices havebeen a standard of the industry for over 45 years. Manythousands of these units are now in use controlling therelease of extinguishants such as clean agents, C02,water, or dry chemicals. In some systems the device isused as an ALARM device, to sense overheat or fire,and alert personnel. In other systems, it is used as aRELEASE device, to sense fire and actuate fire attacksystems.

DETECT-A-FIRE units have met with wide acceptancebecause they are designed with RATE COMPENSATION.This provides a unique advantage over both fixed tem-perature and rate-of-rise types of detectors becauseonly the DETECT-A-FIRE unit accurately senses thesurrounding air temperature regardless of the firegrowth rate. At precisely the predetermined dangerpoint, the system is activated.

Fixed temperature detectors must be completelyheated to alarm temperature and therefore a disastrouslag in time may occur with a fast rate fire. Rate-of-risedevices, on the other hand, are triggered by the rate ofincrease in ambient temperature and are subject tofalse alarms caused by harmless, transient thermalgradients such as the rush of warm air from processovens.

The secret of the unit's sensitivity is in the design(Figure 1). The outer shell is made of a rapidly expandingalloy which closely follows changes in surrounding airtemperature. The inner struts are made of a lowerexpanding alloy. Designed to resist thermal energyabsorption and sealed inside the shell, the struts followtemperature changes more slowly.

A slow rate fire (Figure 2) will heat the shell and strutstogether. At the "set point," the unit will trigger, actuatingthe alarm or releasing the extinguishant.

A transient rush of warm air up to 40F˚/min. mayexpand the shell, but not enough to trigger the unit. Byignoring transient warm air excursions, the DETECT-A-FIREunit virtually eliminates false alarms prevalent withrate-of-rise devices.

If a fast rate fire (Figure 3) starts, the shell will expandrapidly. The struts will close, actuating the alarm orreleasing the agent. The faster the fire rate of growth,the sooner the DETECT-A-FIRE unit will react.

HORIZONTAL DETECT-A-FIRE-UNITSHorizontal detectors are designed for locations whereappearance is a factor. The attractive, functional design lendsphysical protection of the unit while making it suitable forcommercial, industrial, mercantile and public buildings,institutions and ships in non-hazardous locations (thoseclassified as "ordinary" under the National Electric Code).Flush mounted units are designed to fit standard 4" octagonalelectrical boxes and surface mounting units are designed tomount directly on ceilings or on 4" electrical junction boxes.Canadian Electrical Codes requires mounting only to anelectrical junction box.

VERTICAL DETECT-A-FIRE-UNITSVertical detectors are designed for use in both "ordinary" or"hazardous" locations. For "ordinary" use, they may bemounted to any approved junction box with 7/8" diameteropening by using 1/2-14 NPT mounting nuts. The device maybe wired in or out of conduit, depending on localpreference and codes. Four leadwires are provided onnormally open vertical units (that close on temperature rise),per UL requirement, to facilitate supervision of system wiring.Instruments are Underwriters Laboratory and UnderwritersLaboratory of Canada listed and Factory Mutual approved forhazardous locations, when mounted in a suitable fitting.

MOUNTINGDETECT-A-FIRE units are not position sensitive. Horizontaland vertical detectors refer to the most common mountingconfiguration for that unit. However, each type can be mount-ed either horizontally or vertically depending on the applica-tion and installation requirements.

Series 550 Dual Point1/4 DIN Thermocouple Sensing Temperature Controller

FEATURES• UL Component Recognized• CSA Certified• Available in On/Off and Time Proportioning

Control Modes• Dead Band Operation• Travelling Differential• Plug-In Construction• Field Selectable Line Voltage• Lead Break Protection• Line Voltage Compensation• Full Scale Indication

APPLICATIONS• Plastic Processing• Industrial Heating• Metals• Ceramics and Similar Heating Applications

DESCRIPTIONThe Series 550 Dual Point Controller features many

modern, efficient and time-saving innovations such asplug-in construction and two individually adjustablecontrol points. The first set point, adjustable to 100% ofspan, is regulated by a front panel knob; the second setpoint is set from the front by an external screwdriveradjustment in the dial face. Once set, the second setpoint “travels” when the first set point is changed. Thesecond set point is adjustable up to 20% of span aboveor below the first set point. With ON/OFF control on thesecond set point, either high limit or low limit action isfield selectable. The first set point has full scale indication,the second is nonindicating. A red pilot light (LED) indicatesthat the first set point output is energized. A green pilotlight (LED) indicates that the second point relay isenergized.

The Series 550 Dual Point Controller operates withstandard types J and K thermocouples and is availablein overlapping ranges from 0 to 2000˚F (-20 to +1100˚C).(See Table 1.)

FEATURESAUTO-TUNE®

On-demand AUTO-TUNE automatically adjusts PIDparameters to optimize control even in the mostdemanding applications.

Configurable Control ModesON/OFF, P, PI, PD, PID, PID AUTO-TUNE.

Front Key OperationOnly four tactile-feedback keys are required for configuration.Parameters are easily changed by scrolling through twosimple menus.

Dual Digital DisplaysSet point and process variable are constantly shown ontwo, four-digit, seven-segment, red LED displays. Displaysalso indicate menu parameters, symbols and error codes.

Loop Break Alarm (optional; requires one alarm)Monitors and protects an entire temperature controlsystem. Detects heater breaks, thermocouple or RTDfailure, short circuits or the failure of operating devicessuch as mechanical relays, SSR’s and SCRs.

Selectable Process Variable ReadoutTemperature ranges may be displayed in ˚F or ˚C. Whencurrent (mA) or voltage (VDC) process inputs are used,the readout is scaled in engineering units from 0-100% ofrange.

Adjustable Range LimitsRange limits can be configured from the front panel torestrict set point adjustments.

Sensor FailureSensor failure causes an error code to be displayed andoutput to be discontinued immediately (to less than 0% ifreverse acting, greater than 100% if direct acting).

Nonvolatile EEPROM MemoryRetains configuration parameters without batterybackup in the event of a power failure.

System CalibrationSystem offset can be compensated for through a selectable input bias which adds to or subtracts fromthe process variable.

Universal Operating VoltagesAccepts operating voltages from 85 to 264 VAC, 50/60 HZ.

SecurityA multi-level key lock function, which prevents unauthorizedadjustments, can be engaged.

Overshoot SuppressionReset inhibitor minimizes overshoot on start-up

Two Alarm Relays (optional)Each relay can be configured as a high, low or deviationalarm and also configured to actuate auxiliary(ON/OFF) switching for heating and or cooling.

Heater Break Alarm (optional)Monitors the load via an external current transformer andsignals when the current falls below the preset value.
