Description

The System Sensor 5621 provides clear markings on the exterior of the unit to ensure that the proper detector is being use. Alphanumeric characters identify the activation method, as well as the temperature rating, in Fahrenheit and Celsius degrees. Fixed temperature models are identified FX, while combination fixed/ rate-of-rise units are marked FX/ROR. The 5600 series also provides a post-activation indicator in the form of a collector. When the detector is activate, the collector drops from the unit, making it easy to identify the unit in alarm.

The 5600 series offers a full-line of configurations to accommodate a broad range of applications. Both single- and dual-circuit models are available for low- and high temperature ratings with either fixed temperature or combination-fixed-temperature/rate-of-rise (ROR) activation. The ROR element of the fixed/ROR models is restorable to accommodate field-testing.

To satisfy a variety of installation needs, the System Sensor 5621 easily mounts to single-gang and octagonal back boxes. And these models accommodate 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.
