Kidde 73-117068-047 Interface Module

Kidde 73-117068-047 AlarmLine™ Linear Heat Detector provides early detection of fire or overheating conditions by detecting changes in temperature in localized areas or over its entire length. It is especially suited for confined areas or harsh environments where adverse ambient conditions cause other detection devices to be unreliable or difficult to use. The system consists of two major components: a small diameter sensor cable and an interface module.The sensor cable is constructed with a negative temperature coefficient material, where a change in temperature results in an exponential decrease in resistance of the sensor. The interface module interprets this resistance change and provides an output to a control panel once the field programmable alarm set point is exceeded
