The HM intelligent thermal sensors are plug-in type fire sensors that use
a single thermistor sensing circuit to provide early warning of developing
fires, together with addressable communication with the fire panel.
The HM-RHSE provides fixed 58°C and rate-of-rise (10°C/minute) temperature
sensing (Class A1R).
These sensors are designed for open area protection and must only be connected to fire panels that
use a compatible proprietary communication protocol for monitoring and control. The detectors
have two integral red LEDs that provide 360° local visual indication of the device status.
