Honeywell Morley S200A HM-RHSE-S2 58°C Rate of Rise Thermal Detector

The Honeywell Morley HM-RHSE-S2 forms part of the S200A range of intelligent addressable thermal sensors designed for fast, dependable fire detection across commercial, industrial, and institutional property safety networks. Equipped with a low-mass thermistor and onboard microprocessor processing, the device provides dual-action response by triggering an alarm if the ambient temperature rises rapidly at a rate exceeding 10°C per minute or crosses a fixed static threshold of 58°C (EN 54-5 Class A1R). It is ideal for spaces prone to dust, steam, or ambient pollutants—such as commercial kitchens, boiler rooms, workshops, and plant facilities—where optical smoke sensors are subject to false alarms. Operating on Honeywell’s Advanced Protocol with built-in signal smoothing filters, it features mechanical decade rotary address switches, dual 360° visual status LEDs, B501AP base compatibility, and full LPCB EN 54-5 approval.
