5600 Series mechanical heat detectors offer property protection against fire and are intended for non-life-safety installations where smoke detectors are inappropriate. To satisfy a variety of installations, the 5600 Series models easily mount to various types of back boxes. The mounting brackets are reversible to allow for flush- and surface-mount back box installations. The 5600 Series provides clear markings on the exterior of the unit to ensure that the proper detector is being used. Alphanumeric characters identify the activation method and the temperature rating in both Fahrenheit and Celsius. The 5600 Series also provides a collector as a post-activation indicator. Once the detectors have been activated, the collectors drops from the effected units to allow easy identification of the specific unit in alarm.
