Edwards Signaling E-HD

Intelligent Analog Fixed Temperature Heat Detector

  • Factory New
Brand: Edwards Signaling FireAlarm.com Part #: 38713 Categories: , Manufacturer Part #: E-HD


This intelligent analog device can be configured as either a 135F fixed temperature heat sensor, or a combination rate-of-rise with fixed temperature. The heat sensor monitors the temperature of the air and determines whether an alarm should be initiated. The E-HD is capable of performing comprehensive self-diagnostics and storing the data.

Thanks to its advanced thermistor technology, the E-HD detector is ideal for sensing fast, flaming fires and for applications where smoke detection is inappropriate. It is particularly well-suited to areas such as laundries and industries where fluctuations in ambient temperature is expected.
