The Notifier 2020R is a conventional rate-of-rise heat detector from the System Sensor Vision range, approved to EN54-5 Class A1R (58°C). It has both rate-of-rise and static elements and uses an ASIC for quick and accurate detection.
It suits areas where the ambient temperature does not normally change quickly. Use it on conventional fire alarm zones with a compatible Vision detector base.
