Description

The Apollo XP95 55000-640APO is an Optical IS Smoke Detector that incorporates a pulsing LED that is locked in a labyrinth withing the housing of the detector. The labyrinth is designed to exclude light from any external source. A photo-diode is placed at an angle to the LED which, in clear conditions, does not receive light directly from the LED. The Apollo 55000-640APO transmits a clear air signal to the control panel. When smoke enters the labyrinth, the light is scattered onto the photo-diode, and the signal to the panel increases. The signal is processed by the electronic circuitry and transmitted to the control equipment in exactly the same way as in the case of the ionization smoke detector

The 55000-640APO XP95 I.S. Optical Smoke Detector is suitable for mounting on 45681-215APO XP95 I.S. Mounting Base. For higher water ingress protection, the 45681-217APO Deckhead Mounting Box can be used.
