Practice Quiz #1 Flashcards
(16 cards)
The fire detection system that uses two wires imbedded in a ceramic core within a tube is the
Kidde system
Why does one type of Fenwal fire detection system use spot detectors wired in parallel between two separate circuits?
So that a single fault may exist in the system without sounding a false alarm.
The most satisfactory extinguishing agent for an electrical fire is [2]
CO2
Which of the following fire detection systems uses heat in the normal testing of the system? [2]
The thermocouple system and the Lindberg system.
What retains the nitrogen charge and fire-extinguishing agent in a high rate of discharge (HRD) container?[2]
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.
Which of the following is the safest fire-extinguishing agent to use from a standpoint of toxicity and corrosion hazards?
Bromotrifluoromethane (Halon 1301).
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.
A fuel or oil fire is defined as a
class B fire.
How is the fire-extinguishing agent distributed in the engine section?[2]
Spray nozzles and perforated tubing.
After a fire is extinguished, or overheat condition removed in aircraft equipped with a Systron-Donner fire detector, the detection system
automatically resets.
Which of the following fire detection systems are commonly used in an engine nacelle? X
Kidde continuous-loop.
For fire detection and extinguishing purposes, aircraft power plant areas are divided into fire zones based on X
the volume and smoothness of the airflow through engine compartments.
A continuous-loop fire detector is what type of detector?X
Overheat detector.
What is the operating principle of the spot detector sensor in a fire detection system?X
A bimetallic thermos switch 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.
