Conventional Heat Detector

The SD119 series include 2-wire and 4-wire detectors, which provide fast and reliable response for photoelectric smoke and heat (135°F) detection. While the smoke and heat detection circuits operate independently, their outputs being "OR' connected, The SD119 series detectors provide the fire detection performance by acting as a smoke sensor and/or a 13°F heat detector at the same location.

Product Features:

2 or 4 wire models
Advanced detection and discrimination algorithms
Easy installation and maintenance
Sleek low-profile housing design
Durable sensor head, no need for replacement
