Answer:

a life-dated unit.Question 3: What is the principle of operation of the continuous-loop fire detector system sensor?

Answer:

Core resistance material which prevents current flow at normal temperatures.

Question 4: A continuous-loop fire detector is what type of detector?

Answer:

Overheat detector.

Question 5: Refer to Figure 2.) Determine the fire extinguisher container pressure limits when the temperature is 75 degrees Fahrenheit.

Answer:

338 minimum and 424 maximum.Question 6: Why does one type of Fenwal fire detection system use spot detectors wired in parallel between two seperate circuits?

Answer:

So that a single fault may exist in the system without sounding a false alarm.

Question 7: The most satisfactory extinguishing agent for an electrical fire is

Answer:

carbon dioxide.

Question 8: A fuel or oil fire is defined as a

Answer:

Class B fire.Question 9: The fire detection system that uses a single wire surrounded by a continuous string of ceramic beads in a tube is the

Answer:

Fenwal System.Question 10: How are most aircraft turbine engine fire-extinguishing systems activated?

Answer:

Electrically discharged cartridges.Question 11: The fire detection system that uses two wires imbedded in a ceramic core within a tube is the

Answer:

Kidde system.Question 12: What retains the nitrogen charge and fire-extinguishing agent in a high rate of discharge (HRD) container?

Answer:

Breakable disk and fusible disk.

Question 13: A fire detection system operates on the principle of buildup of gas pressure within a tube proportional to temperature. Which of the following systems does this statement define?

Answer:

Lindberg continuous-element system.Question 14: Which of the following is the safest fire-extinguishing agent to use from a standpoint of toxicity and corrosion hazards?

Answer:

Bromotrifluoromethane (Halon 1301).Question 15: The most satisfactory extinguishing agent for a tailpipe or intake fire is

Answer:

carbon dioxide.Question 16: After a fire is extinguished, or overhead condition removed in aircraft equipped with a Systron-Donner fire detector, the detection system

Answer:

automatically resets.Question 17: Which statement best describes the blowout type indicator disk on a fixed fire extinguishing system?

Answer:

When the yellow indicator disk is missing, it indicates the fire extinguishing system has been normally discharged.Question 18: Which of the following is NOT used to detect fires in reciprocating engine nacelles?

Answer:

Smoke detectors.Question 19: Which of the following fire detection systems will detect a fire when an element is inoperative but will not test when the test circuit is energized?

Answer:

The Kidde system and the Fenwal System.

Question 20: A fire involving energized electrical equipment is defined as a

Answer:

Class C fire.Question 21: Two continuous-loop fire detection systems that will not test due to a broken detector element are the

Answer:

Kidde system and the Fenwal system.Question 22: Which of the following fire detection systems uses heat in the normal testing of the system?

Answer:

The thermocouple system and the Lindberg system.Question 23: A fire detection system that operates on the rate-of-temperature rise is a

Answer:

Thermocouple system.Question 24: What is the operating principle of the spot detector sensor in a fire detection system?

Answer:

A bimetallic thermoswitch that closes when heated to a high temperature.Question 25: The pulling out (or down) of an illuminated fire handle in a typical large jet aircraft fire protection system commonly accomplishes what events?

Answer:

Closes fuel shutoff, closes hydraulic shutoff, disconnects the generator field, and arms the fire-extinguishing system.Question 26: Which of the following fire detection systems measures temperature rise compared to a reference temperature?

Answer:

Thermocouple.
