Standalone Smoke / Heat Detector  

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.
