Fire Protection Flashcards
Systems that make up fire protection
Detection and extinguishing
Parts of fire protection system
Sensor , control unit , panel
Where is the sensor
Monitored area
Where is the control unit
Avionic deployment
Where is the panel located
Cockpit
Continuous loop detection system types
Semi conductor and pneumatic pressure
Types of smoke detector systems
Optical and ionisation
What happens in a semi-conductor as temperature increases
There is a decrease in electrical resistance
Semi conductor manufacturers
Kidde , graviner , Edison , Fenwal
Pressure loop manufacturer
Systron and doner
How does pressure loop work
As temp increases the gas pressure operates a switch
Where is the smoke detector used
Cargo department, toilets , avionic department
What smoke detector uses a radiation source
Ionisation type
How is fire warning indicated
Red attention getters and messages on ECAM or EICAS
When is fire detection indicated on a duel loop system
When sensors detect at the same time
Addition features of apu detection
Automatic shut down , red flashing light , horn in wheel well
Areas covered by detection system
Engines , apu wheel wells , cargo areas
What type of sensor is a spot sensor
Bi-metallic switch
How do discharge heads relate to cargo
Heads connected to bays by pipes to distribute extinguisher fluid via flow limiters
Cargo class A
No fire detection or extinguishing
Class B cargo
Fire detection because ventilated but no extinguishing
Class C cargo
Detection and extinguishing as ventilated and not accessible
Class D cargo
Same as class C after 2003
Class E cargo
Detection needed only
