Product Code: 485843



The FireLite Alarm H355 Series thermal detectors are addressable sensors that use a state-of-the-art thermistor sensing circuit for fast response. These sensors are designed to provide open-area protection and are intended for use with FireLite's MS-9600 and MS-9200UD Fire Alarm Control Panels (FACPs).

Both the H355 and H355R sensors provide fixed temperature alarm detection at 135F. The H355R sensor responds to rate-of-rise conditions of greater than 15F/8.3C per minute. H355HT provides fixed high-temperature detection at 190F/88C. These thermal detectors provide cost effective, 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 as an optional accessory (P/N RA400Z).

    SLC loop:
    • Two-wire SLC loop connection.
    • Unit uses base for wiring.
    • Addressable by device.
