Purpose The engine and APU fire detection module monitors detectors for overheat and fire conditions on the engine. Also it monitors for fire conditions on the APU. Physical Description The control circuits for the engine overheat and fire, and the APU fire detection are in the module. The front panel has these components: * ENGINE 1 LOOP A amber fault light * ENGINE 1 LOOP B amber fault light * ENGINE 2 LOOP A amber fault light * ENGINE 2 LOOP B amber fault light * APU amber fault light * Three red FAULT DISPLAY lights * FAULT/INOP test switch. Location The engine and APU fire detection module is on the electronic equipment compartment on the E2-2 shelf. Operation During normal conditions, all front panel lights are off. When a fault condition occurs, the related FAULT AREA light comes on. The FAULT DISPLAY lights show a fault code. When you push the FAULT/INOP test switch, faults are simulated to do a check of the circuit ability to detect a fault. If the circuits operate correctly, all lights on the front panel come on. If a light does not come on, it shows a faulty circuit operation. The FAULT DISPLAY lights show the type of fault and the detector location. Fault Signal Priorities When there are multiple engine loop faults (two or more amber lights on), this is the display priority: Highest Priority Engine 1 Loop A Engine 1 Loop B Engine 2 Loop A Engine 2 Loop B Lowest Priority APU FIRE PROTECTION - ENGINE FIRE DETECTION - ENGINE AND APU FIRE DETECTION MODULE EFFECTIVITY AMX ALL 26-11-00 Page 8 Jun 10/2003 D633A101-AMX BOEING PROPRIETARY - Copyright # - Unpublished Work - See title page for details. 737-600/700/800/900 AIRCRAFT MAINTENANCE MANUAL 26-11-00-004

Functional Description The OVHT DET switch on the engine and APU fire control panel permits selection of the mode of operation. Each switch has these positions: * NORMAL - makes loop A and loop B agree before the alarm condition operates * A - makes loop A the only sense authority * B - makes loop B the only sense authority.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
