Conventional Heat Detector 2 wired Temperature Sensor Fixed Temperature Alarm Heat Alarm

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 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.
