SD119-G Series

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.
