AlarmLine Addressable Linear Heat Detector - …

1 TMEffective: March 2008K-73-02 AlarmLine AddressableLinear heat DetectorP/N 73-100001-003 DESCRIPTIONThe AlarmLine Addressable Linear heat Detectorprovides early detection of fire or overheat condition inprotected areas or equipment. It is especially suited forconfined areas or environments where adverse ambientconditions cause other detection devices to be unreliableor difficult to use. The Detector consists of two majorcomponents: A sensor cable and an AddressableAlarmLine Module (AAM).

4 System sensitivity remainsconstant as ceiling height increases without Circuit Discrimination: The system will producea trouble condition instead of a false alarm in the event ofa conductor to conductor short due to damage orelectrical CABLEThe AlarmLine sensor cable consists of four 26 AWGcopper conductors, each color-coded in an insulatedsheath containing a negative temperature coefficientpolymer (where an increase in temperature decreasesthe resistance of the sensor).Two of the conductors are enameled and provide loopcontinuity supervision, but not temperature sensing.

5 Theconductors are twisted at thirty turns per foot (90 turnsper meter) and protected by a flame-retardant outerextrusion or metallic braid (See Figure 1). The colorcoding of the four inner conductors is repetitively markedon the outer coating every three feet as an aidinstallation. Cable is sold in standard coils of 656 feet(200 meters) and 3280 ft. (1000 m).Note:The maximum length of sensor cable per zone depends on the maximum ambient temperature defined on the nomogram(s) (See Figures 2 and 3).

6 Regardless of ambient temperature, however, the maximum length of cable is 3280 feet (1000 meters) per zone for Type T 1. Standard Sensor CablePART NUMBERSS ensor cable is available with the following part numbers:Standard Sensor Cable73-117068-013 (656 m) 73-117068-113 (3280 m)Recommended for environments ranging from clean anddry to moderate dust and Coated Sensor Cable73-117068-016 (656 m) 73-117068-116 (3280 m)Recommended for use in wet, oily, or corrosiveenvironments or outdoors. Use in freezer Bronze Braided Sensor73-117068-019 (656 m) 73-117068-119 (3280 m)Recommended for applications requiring superiorabrasion protection and/or increased tensile AlarmLine MODULE (AAM)The AAM permits an AlarmLine sensor cable to bedirectly interfaced to any control panel that acceptsSmartOne Addressable loop devices.

7 This interface willallow for pre-alarm, alarm, and trouble conditions to betransmitted to the control panel via the Signaling LineCircuit (SLC). The AAM monitors the resistance of thesensor cable and generates a pre-alarm (if enabled),alarm, or overheat output (if enabled) when theresistance drops below the programmed threshold. Themodule also supervises the AlarmLine cable for opensand shorts, which will generate a fault of the pre-alarm, alarm, overheat, and troubleconditions will be displayed on the control panel.

8 Up to255 AAM modules can be connected to a single SLCloop. Use of multiple AAMs allows flexibility in zoninglarger installations for location of alarm and zone outputcontrol; the control panel acts as a central display andcontrol AAM receives power directly from the SLC loopwhich eliminates the need for additional wiring andexternal power SENSORPROTECTIVE INSULATIONHIGH TEMPERATURE PVCSENSOR CONDUCTORWIRENEGATIVE TEMPERATURECOEFFICIENT MATERIAL- 3 -For further information on installation and configuration ofthe AAM, please refer to the AlarmLine AddressableLinear heat Detector Installation, Operation, andMaintenance Manual.
