QuestionAnswer
What is the principle of operation of the continuous-loop fire detector system sensor? Core resistance material which prevents current flow at normal temperatures.
Which of the following is the safest fire-extinguishing agent to use from a standpoint of toxicity and corrosion hazards? Bromotrifluoromethane (Halon 1301).
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? Lindberg continuous-element system.
Which of the following fire detection systems uses heat in the normal testing of the system? The thermocouple system and the Lindberg system.
The fire detection system that uses a single wire surrounded by a continuous string of ceramic beads in a tube is the Fenwal System.
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? The Kidde system and the Fenwal System.
A fire detection system that operates on the rate-of-temperature rise is a Thermocouple system.
Refer to Figure 2.) Determine the fire extinguisher container pressure limits when the temperature is 75 degrees Fahrenheit. 338 minimum and 424 maximum.
A continuous-loop fire detector is what type of detector? Overheat detector.
The fire detection system that uses two wires imbedded in a ceramic core within a tube is the Kidde system.
(Refer to Figure 3.) What are the fire-extinguisher container pressure limits when the temperature is 50 degrees Fahrenheit? 475 - 625 psig.
Which of the following fire detection systems measures temperature rise compared to a reference temperature? Thermocouple.
The use of water on Class D fires will cause the fire to burn more violently and can cause explosions.
How does carbon dioxide (CO(2)) extinguish an aircraft engine fire? Contact with the air converts the liquid into snow and gas which smothers the flame.
How are most aircraft turbine engine fire-extinguishing systems activated? Electrically discharged cartridges.
For fire detecting and extinguishing purposes, aircraft powerplant areas are divided into fire zones based on the volume and smoothness of the airflow through engine compartments.
The pulling out (or down) of an illuminated fire handle in a typical large jet aircraft fire protection system commonly accomplishes what events? Closes fuel shutoff, closes hydraulic shutoff, disconnects the generator field, and arms the fire-extinguishing system.
A fuel or oil fire is defined as a Class B fire.
A fire involving energized electrical equipment is defined as a Class C fire.
Which of the following is NOT used to detect fires in reciprocating engine nacelles? Smoke detectors.
After a fire is extinguished, or overhead condition removed in aircraft equipped with a Systron-Donner fire detector, the detection system automatically resets.
The most satisfactory extinguishing agent for a tailpipe or intake fire is carbon dioxide.
Which statement best describes the blowout type indicator disk on a fixed fire extinguishing system? When the yellow indicator disk is missing, it indicates the fire extinguishing system has been normally discharged.
How is the fire-extinguishing agent distributed in the engine section? Spray nozzles and perforated tubing.
What is the operating principle of the spot detector sensor in a fire detection system? A bimetallic thermoswitch that closes when heated to a high temperature.
Two continuous-loop fire detection systems that will not test due to a broken detector element are the Kidde system and the Fenwal system.
What retains the nitrogen charge and fire-extinguishing agent in a high rate of discharge (HRD) container? Breakable disk and fusible disk.
What is the function of a fire detection system? To activate a warning device in the event of a powerplant fire.
The most satisfactory extinguishing agent for an electrical fire is carbon dioxide.
The explosive cartridge in the discharge valve of a fire-extinguisher container is a life-dated unit.
Why does one type of Fenwal fire detection system use spot detectors wired in parallel between two seperate circuits? So that a single fault may exist in the system without sounding a false alarm.
Which of the following fire detection systems are commonly used in an engine nacelle? Kidde continuous-loop.
