2 wire 9-28VDC Temperature Detector Heat Sensor for fire alarm system
General Description
The device is intelligent sensors that utilize a state-ofthe-art thermistor sensing circuit for fast response.These sensors are designed to provide open area
protection with 50 foot spacing capability. The deviceis a rate-of-rise temperature sensor with 135°F fixed temperature alarm. The device is a rate-of-rise with fixed temperature
alarm thermal detector utilizing a state-of-the-art dual thermistor sensing circuit. These detectors are designed to provide open area protection with 50-foot
spacing capability, and are to be used with compatible control panels only.
Two LEDs on each detector light to provide 360°visibility of the detector indication.
