G650 - Fire Protection
The fire detection rails are comprised of two redundant continuous-loop detector elements. Each continuous loop detector is capable of indicating a fire warning if temperatures equal or exceed 100 deg.C above the maximum operating temperature of 125 deg.C.
What happens when a fire handle is pulled?
Which bottle can be discharged into the APU?
If smoke is present in the baggage compartment or anywhere in the aircraft interior, it may be evacuated to remove smoke from the interior of the aircraft. A manually operated valve, installed above the baggage compartment access door on the cabin side allows for smoke removal. At the completion of smoke evacuation, normal pressurization of the baggage compartment cannot be restored unless the aircraft is at or below 25,000 ft.
At the completion of smoke evacuation, normal pressurization of the baggage compartment can be restored via a Valve Reset toggle switch next to the smoke evacuation handle. It must be held to the reset position for 10 seconds to open the baggage compartment shutoff valve to restore pressurization to the baggage compartment.
Fire testing, detection, and protection is available down to what source of power?
Where is the location of the fixed bottles?
How are fire handles normally locked in the stowed position?
The handles are locked in the normal down position and a 28V DC signal must be applied to a lock release solenoid in the handles for them to be pulled to the fire position. The handles incorporate a manual release button which will permit the handles to be pulled in the event of a solenoid failure. The handles incorporate lights behind a red lens cap. These lights illuminate when a fire alarm is generated by the control unit.
All components of the fire and overheat detection system are powered through the essential DC buses, enabling aircraft main battery power to energize the system for protection during APU and/or engine starting.
The FIRE TEST switches are normally operational as soon as power is applied to the left and right essential DC buses.
The two fire extinguishing bottles are mounted:
