System Sensor 5603 Product Description:


The System Sensor 5603 is a 5600-series, 135°F fixed temperature, single-circuit, mechanical heat detector. The 5603 detector offers a low-cost means for property protection against fire, and for non-life-safety installations where smoke detectors are inappropriate. Add the hardwired 5603 heat detector to most existing alarm system control panels.

To satisfy a variety of installation needs, the 5603 easily mounts to single-gang and octagonal back boxes. And the 5603 accommodates four-square back boxes, when used with a square to round plaster ring. The reversible mounting bracket permits both flush and surface-mount back box installations.

The 5603 provides clear markings on the exterior of the unit to ensure that the proper detector is being used. Alphanumeric characters identify the activation method, as well as the temperature rating, in Fahrenheit and Celsius degrees. The 5603 is a fixed temperature model and identified by an FX. The 5603 also provides a post-activation indicator in the form of a collector. When the detector is activated, the collector drops from the unit, making it easy to identify the unit in alarm.
