Fire Protection (Ng)

Front 1

Where is overheat/fire/smoke protection provided?

Back 1

It is provided in:
- Engines
- APU
- Wheel well
- Cargo compartments

Front 2

How many loops are in each engine? How many can you departure with not operating? How many loops are in the mian wheel well and APU?

Back 2

There is 2 loops, A & B. You can depart with 1 inoperative.

There is only 1 fire detection loop in each of the APU and mian wheel well.

Front 3

During the fire/overheat warning test, how is a single loop fault indicated?

Back 3

when the switch is positioned to OVHT/FIRE during a system test, if there is a single loop fault, the Engine Fire Switch of the affected engine does not illuminate.

Front 4

What must be available to test the main wheel well fire detection loop?

Back 4

AC power must be available.

Front 5

What 2 locations can the APU fire warning be silenced and fire extinguisher activated?

Back 5

From the cockpit or the main right wheel well.

Front 6

How many loops are provided for smoke detection in the cargo compartment? How many must be working to depart?

Back 6

2 loops are provided in each compartment (FWd & AFT). You can depart with 1 inoperative.

Front 7

How is a single loop failure indicated?

Back 7

When the TEST P/B is pushed and these is a single loop fault, the Cargo Fire warning Light of the affected cargo compartment does not illuminate.

Front 8

Which power source is used for:
- Engine/APU fire detection
- Engine, APU & Cargo compartment fire extinguishing

Back 8

- Battery bus
- Hot battery bus

Front 9

Pulling the Engine Fire Switch causes what 7 things to occur?

Back 9

1. Arms one squib on each engine fire extinguisher bottle
2. Closes the engine and spar fuel shutoff valves
3. Trips the affected generator
4. Closes the hydraulic shutoff valve and deactivates the engine driven hydraulic LOW PRESSURE light
5. Closes the engine bleed valve (resulting in loss of wing anit ice to affected wing and the associated pack)
6. Disbales thrust reverser for affected engine
7. Allows the Engine Fire Switch to be rotated for discharge

Front 10

When the Extinguisher Test Switch is postioned to 1 or 2, what occurs and what does this indicate?

Back 10

The green extinguisher test lights illuminate, verifying circuit continuity from the squib to the Engine Fire Switch.

Front 11

Pulling the APU Fire Switch cause what 7 things to occur?

Back 11

1. Provides backup to automatic shutdown feature
2. deactivates the fuel solenoid and closes the APU fuel shutoff valve
3. Closes the APU bleed valve
4. Closes the APU inlet door
5. Trips the APU generator
6. Arms the APU fire extinguisher bottle squib
7. Allows the APU Fire Switch to be rotated for discharge

Front 12

How to you ARM and discharge the 1 extinguisher bottle into the cargo compartment?

Back 12

The extinguisher is armed by pushing the appropriate cargo fire ARMED switch. Subsequently pushing the cargo fire DISCH switch results in total discharge of the bottle into the selected compartment.

Front 13

The cargo fire extinguisher provides protection for how long?

Back 13

It provides extinguishing and additional protection for at least 60 mins.

Front 14

How many nozzles are provided for lavatory fire extinguisher? How are they activated? What 2 things tell you the extinguisher has been discharged?

Back 14

There are 2 heat activated nozzles provided for lavatory fire extinguishing. The nozzle tips will change to a 'silver' colour to indicate the extinguisher has been discharged. Also, a temperature placard with white dots will change to black dots if the extinguisher has been discharged.

Front 15

How is lavatory smoke indicated to the Flight and Cabin Crew?

Back 15

Lavatory smoke causes the illuminattion of the amber SMOKE light on the overhead panel. A red alarm indicator is also activated on the lavatory smoke detector panel.

Front 16

Amber FAULT light, on the Fire/Overheat detection control panel, indicates?

Back 16

Amber FAULT light indicates:
With overheat detector switch in NORAML - both detection loops have failed
With overheat detector switch in A or B - the selected loop has failed.

Front 17

The APU DET INOP light indicates?

Back 17

Indicates the APU detection loop has failed.
