CONVENTIONAL PHOTOELECTRIC SMOKE DETECTOR AH388
The AH-388 series include 2-wire and 4-wire detectors, which provide fast and reliable response for photoelectric smoke detection. While the smoke and heat detection circuits operate independently, their outputs being “OR’ connected.
Description
All of the Chloride Uk AH388 series detectors meet the requirements of UL268 and UL521 (ordinary) and EN54-7 and EN54-5 (A2S) for use in fire alarm signalling systems. They are intended for use in 2-wire/4-wire Class A or B supervised zone circuits. The AH-388 series detectors are subject to panel compatibility limits and compliance with corresponding NFPA 72 standards, local codes, and ordinances.
The AH-388 series include 2-wire and 4-wire detectors, which provide fast and reliable response for photoelectric smoke detection. While the smoke and heat detection circuits operate independently, their outputs being “OR’ connected.
