Text 3. Wheel Well Fire Detection and Lavatory Fire Protection

A fire detection loop is installed in the main gear wheel well. In the event of a fire or overheating in this area, the wheel well fire light illuminates red on the fire control panel, the master fire warning lights light illuminates red on the glareshield and a bell sounds in the flight deck.

A smoke detector is located in the ceiling of each lavatory, and an automatic fire extinguisher system is located beneath the sink area in each lavatory. The extinguisher automatically discharges halon gas through one or both of two heat-activated nozzles whenever the temperature rises sufficiently to melt the nozzle tips. One nozzle discharges into the towel disposal container, the other directly under the sink. There is no indication on the flight deck.
