weight and easily adaptable to any mounting position. 9. Detector circuitry that operates directly from the aircraft power system without inverters. 10. Minimum electrical current requirements when not indicating a fire. 11. Each detector system should turn on a flight ... deck light, indicating the location of the fire, and have an audible alarm system. 12. A separate detector system for each engine. Engine Fire Detection Systems Several different types of fire detection systems are installed in aircraft to detect engine…

Smoke Detector System The optical smoke detector consists of source light emitting diodes (LEDs), intensity monitor photodiodes, and scatter detector photodiodes. Inside the smoke detection chamber, air flows between a source LED and a scatter detector photodiode. Usually, only ... small amount of light from the LED gets to the scatter detector. If the air has smoke in it, the smoke particles reflect more light on the scatter detector. This causes an alarm signal. The intensity monitor photodiode makes sure…

Pneumatic Thermal Fire Detection Pneumatic detectors are based on the principles of gas laws. The sensing element consists of a closed helium-filled tube connected at one end to a responder assembly. As the element is heated, the gas pressure ... fault alarm if the pneumatic detector losses pressure, as in the case of a leak. Continuous-Loop Detector Systems Large commercial aircraft almost exclusively use continuous thermal sensing elements for powerplant protection, since these systems offer superior detection performance…
