DEMCO SMOKE DETECTOR - UL LISTED (D-233)

DEMCO Single Station Photoelectric Smoke Detector D-223 is a battery operated, 9V single station smoke alarm specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories and other multi-family dwellings. It is designed to give early warning of developing fires by giving off an audible alarm from its built-in alarm horn. This provides precious time for escape before a fire spreads.
