4-Wire Conventional Fire Smoke Heat Alarm with Relay Output

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