Ideal for locations that are dirty or smoky under normal conditions such as engine and generator rooms, this detector is designed to alarm at ambient temperatures of 170°F or higher. The Heat Detector monitors temperature by using a dual thermistor network, which provides a voltage output proportional to the external air temperature. The LED is clear in a normal state and produces a red light in an alarm state. Operation from 10V to 30 V DC. 4"dia. x 2"D.
