Fire•Lite Alarms H355(A) Series

thermal detectors are addressable sensors that use a state-of-the-art thermistor sensing circuit for fast response. These sensors provide open-area protection and are intended for use with

Fire•Lite’s addressable

Fire Alarm Control Panels (FACPs). The H355(A) and H355R(A)

sensors provide fixed temperature alarm detection at 135°F (57°C). The

H355R(A) sensor also responds to rate-of-rise conditions of greater than 15°F

(8.3°C) per minute. The H355HT(A) is a fixed high-temperature detector that activates at 190°F (88°C). These thermal detectors provide addressable property protection in a variety of applications. Two LEDs on each sensor light to provide a local, visible sensor indication. Remote LED annunciator capability is available using an optional accessory, the RA100Z.
