SD119-G 2/4 Wire Smoke Detector Sensor for Home Security System Wide Voltage Range Smoke Alarm with Relay Output 12v 24v 48v 60v UL

Conventional Photoelectric Smoke and Heat Alarm

All of the Sentek’s SD119-G series detectors meet the requirements of UL 268 and EN 54-7/5 for use in fire alarm signaling systems. They are intended for use in 2-wire/4-wire Class A or B supervised zone circuits. The SD119 series detectors are subject to panel compatibility limits and compliance with corresponding NFPA 72E standards, local codes, and ordinances.

The SD119-G 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 Sentek’s SD119-G series detectors provide the fire detection performance by acting as a smoke sensor and/or a 135°F heat detector at the same location.
