Notifier Europe 2020HF High fixed temperature thermal BS (78°C)

The Notifier 2020HF is a conventional 78°C high fixed-temperature heat detector from the System Sensor Vision range, approved to EN54-5 Class BS. It combines a thermal element with an ASIC for quick and accurate detection.

It has a static element and suits areas where the ambient temperature normally changes quickly above 45°C, such as boiler houses. Use it on conventional fire alarm zones with a compatible Vision detector base.
