Fixed Tempature Heat Detectors


The AS2020 & AS2021 fixed temperature / rate-of-rise heat detector are suited for installation where high heat output fires are expected or in areas where ambient conditions would not allow use of other detection methods. Heat detectors are intended for protection of property. Do not rely on heat detectors for life safety protection. Where life safety is a concern, smoke detectors must also be used. A UL listed fire alarm panel must electronically supervise the AS2020 & AS2021 heat detectors.All conventional devices are mechanically compatible with Avenger bases.
