(MODEL D-223)
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.
The D-223 features a solid-state surface-mount circuitry and are designed for low power consumption, precision and stability.
- Easy to install – install directly to proper location without any wiring.
- Easy to maintain – minimum one year battery life under normal operation.
- Easy to test – the LED alarm indicator doubles as a test button – just press it for 2 seconds and hear the alarm sound to confirm that it is working in normal condition.
- Low battery warning – “unit beeps” every one minute for at least 7 days to indicate battery needs replacing.
