Spot Heat Detectors- 5600 Series

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

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, 3.5 inch octagonal box, or plaster ring. When reversed, the plate can be used for open wiring without a junction box. Electrical rating is 6-28 VDC, 1 amp. (all models). Refer to product data sheet for FM approval and spacing information.


Low profile, rate-of-rise and fixed temperature 135°F, maximum spacing is UL 50′ x 50′ (15.2m x 15.2m)


Low profile, rate-of-rise and fixed temperature 194°F, maximum spacing is UL 50′ x 50′ (15.2m x 15.2m)


Low profile, fixed temperature 135°F, maximum spacing is UL 25′ x 25′ (7.6m x 7.6m)


Low profile, fixed temperature 194°F, maximum spacing is UL 25′ x 25′ (7.6m x 7.6m)
