5600 and 302 Series Heat Detectors

The Protectowire Company offers a complete range of spot type heat detectors designed to accommodate a wide variety of applications and installation environments.

5600 Series Heat Detectors

The 5600 Series Heat Detector is a durable, low profile unit which protrudes only 1.7 inch (4.3cm) from the mounting surface when mounted on a recessed junction box. It is available in combination rate-of-rise and fixed temperature models with temperature ratings of 135°F (57°C) or 194°F (90°C). Each 5600 Series Detector includes a reversible mounting plate which attaches to a 4 inch junction box, 3.50 inch octagonal box, or plaster ring. When reversed, the plate can be used for open wiring without a junction box. Electrical Rating 6-28 VDC, 1 amp. (all models).  Refer to product data sheet for FM approval and spacing information.
