The Notifier 2020F is a conventional 58°C fixed-temperature heat detector from the System Sensor Vision range. It combines a thermal element with an application-specific integrated circuit (ASIC) and is approved to EN54-5 Class A2S.
It has a static element only, so it suits areas where the ambient temperature normally changes quickly, such as kitchens. Use it on conventional fire alarm zones with a compatible Vision detector base.
Key features
