4-wire Heat Detector Heat Alarm Sensor with Relay output

4-wire heat detector with relay output

The device is intelligent sensors that utilize a state-of-
the-art thermistor sensing circuit for fast response.
These sensors are designed to provide open area
protection with 50 foot spacing capability. The device
is 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.
