SensoMag R20

Fire Alarm Systems > Conventional > Detectors

SensoMAG R20 is a rate-of-rise temperature detector with digital processing algorithm. The detector is designed to detect temperatures above 58°C (class A1R, according EN54-5).
SensoMAG R20 is suitable for installing in any conventional fire alarm system designed with fire alarm panel with fire alarm threshold between 10mA and 15mA.
SensoMAG R20 is suitable for applications for locations in which different ambient temperatures occur (e.g. mechanical workshops, tool rooms, etc.). The innovative design makes it particularly suitable anywhere where bust, dirt (e.g. sawmills) or high humidity (e.g. wet cells) could affect the operation of traditional detectors.
