Inside the case a printed circuit board has the optical system mounted on one side and the signal processing electronics on the other. The sensing chamber is a moulding configured as a labyrinth which prevents penetration of ambient light. The labyrinth has a fine gauze insect-resistant cover. The chamber houses an infrared light emitting diode (LED) and a photo-diode which has an integral visible-light filter as an extra precaution against ambient light.  \nEvery three seconds the LED emits a burst of collimated light, modulated at 4 kHz. In clear air light from the LED does not fall directly on the diode because the LED is positioned at an obtuse angle to the diode.  \nWhen smoke enters the chamber a fraction of the collimated light is scattered onto the photo-diode. If the resulting signal from the photo-diode is above a pre-set threshold the LED emits two bursts of light, this time at two-second intervals. If light is scattered onto the photo-diode by both these pulses-due to the presence of smoke-the detector signals an alarm state by switching the alarm latch on inc","cbCaideJV98TN86C","https://ap.wps.com/l/cbCaideJV98TN86C","pdf",404167,"English","# Product information\n## Detection principle\n## Technical data\n## Operating principles\n## Environmental characteristics\n## Standards & approvals","[{\"question\":\"How is the alarm indicated locally and remotely?\",\"answer\":\"Alarm current illuminates the detector’s integral red LED.
