The Apollo 55000-640APO XP95 I.S. Optical Smoke Detector is an explosionproof optical smoke detector. The Apollo 55000-640APO incorporates a pulsing LED located in a labyrinth within the housing of the Detector. The labyrinth is designed to exclude light from any external source. At an angle to the LED is a photo-diode which, in clear air conditions, does not receive light directly from the LED.
This Apollo Smoke Detector transmits a clear air signal to the control panel. When smoke enters the labyrinth, 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.
