Fire Protection System Flashcards
Where are carbon monoxide detectors normally used?
cabin and cockpit
How are thermal switch units wired?
in parallel
What does a continuous loop fire detection system consist of?
flexible small diameter ICONLE tube, relay, amp, alarm
What is used to check a Freon container for pressure?
pressure gauge
What is the indication of excess carbon monoxide fumes when using a CO detector?
visual color change and/or audible alarm
How does a photoelectric smoke detector warn of possible fire?
light refraction due to smoke makes the photoelectric cell conduct current which relays it to the EICAS
How are Fenwal spot detectors wired?
series
Of what does a thermal switch fire detection system consist of?
one or more lights and thermal switches
How may a photoelectric smoke detector be checked?
test switch or a red lensed flashlight
Name two types of smoke detection instruments used in aircraft.
light refraction and ionization
How is a thermocouple fire warning system different from a thermal switch system?
thermocouple=rate of rise, thermal switch= preset temperature rise
What is a continuous loop fire detection system?
single overheat sensing element
What is the purpose of the yellow disc in a fire extinguishing system?
to indicate a normal discharge
What protection is provided for a Freon bottle in case of a temperature rise in excess of set limits?
thermo discharge plug
What type extinguishing agent is usually found in a high rate of discharge system?
nitrogen and Halon 1301
