Engine Fire Protection Flashcards
What type of fire detection system operates on the principle of the rate of temperature rise
Thermocouple system
What would likely cause a false fire warning.
A kinked or bent sensing loop
If there is a break in a single wire continuous loop fire detector element and the system tests bad shill it indicate the presence of a fire
Yes
What is used as a fire extinguishing agent in some older aircraft
Carbon dioxide
What fire extinguishing agent is used in the high-rate discharge bottles installed in a jet transport aircraft
Halon 1211 or 1301
What color and markings is used to identify the fluid lines that carry the fire extinguishing agent in an aircraft
Brown tape with a series of diamonds on it
What two methods are used to discharge a fire extinguishing agent
Mechanical and electrical
Name the examples of spot detection type systems
Thermo switch and thermocouple
Name examples of continuous loop detection systems
Fenwal, Kidde and pneumatic
What method is used to determine proper fire extinguisher container pressure
Check the container gauge
How does the fire extinguishing agent put out fire
Dilutes the oxygen levels so that it will not allow combustion
What does HRD stand for in an HRD fire extinguishing system
High Rate of Discharge
How long does it take to discharge the extinguishing agent in a HRD system and how is it distributed
Distributed through series of high pressure tubes and takes 1 to 2 seconds
Which type of fire detection system gives more complete coverage of a fire hazard than spot type systems
Continuous loop
What type of fire detector systems are used for engine fire detection
Overheat, rate of rise and flam detectors
