XP95 Apollo Intrinsically Safe Optical Smoke Detector 55000-640 one loop panel The signal is processed byOptical smoke detectors incorporate 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. The 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
