The Notifier 2020PT is a conventional multi-criteria detector from the System Sensor Vision range. It combines an optical smoke chamber and a thermal element with detection algorithms.
Using both smoke and heat gives a faster response to real fires and reduces the risk of unwanted alarms from the environment. Use it on conventional fire alarm zones with a compatible Vision detector base.
Key features
