System Sensor 5604 5600 Series 194°F Fixed-Temperature Single-Circuit Mechanical Heat Detector

The System Sensor 5604 is a single-circuit, fixed-temperature mechanical heat detector from the 5600 Series, designed to activate at 194°F. Its exterior markings identify the detector’s activation method and temperature rating, while a drop-down collector provides a visible indication after activation.

The reversible mounting bracket supports flush- or surface-mount installation on single-gang and octagonal back boxes. It can also be installed on a four-square back box when used with a square-to-round plaster ring.
