What occurs when a visual smoke detector is activated?

The types of fire-extinguishing agents for aircraft interior fires are

When air samples contain carbon monoxide, portable carbon monoxide detectors containing yellow silica gel will turn which color?

Smoke detection instruments are classified by the method of

Smoke detectors that use a measurement of light transmissibility in the air are called

A contaminated carbon monoxide portable test unit may be returned to service by

When the detection system measures temperature rise compared to a reference temperature?

A carbon dioxide (CO2 ) hand-held fire extinguisher may be used on an electrical fire if the

The proper fire-extinguishing agent to use on an aircraft brake fire is

Smoke in the cargo and/or baggage compartment of an aircraft is commonly detected by which instrument?

Light refraction smoke detectors are activated when the detector

Why does the Fenwal fire-detection system use spot detectors wired parallel between two separate circuits?

A fire extinguisher container can be checked to determine its charge by

What is the color code for the extinguisher lines?

The most common cause of false fire warnings in continuous-loop fire-detector systems is

A thermocouple in a fire-detection system causes the warning system to operate because

The thermocouple fire-warning system is activated by a

When used in fire-detection systems having a single indicator light, thermal switches are wired in

Built-in aircraft fire-extinguishing systems are ordinarily charged with

In reference to aircraft fire-extinguishing systems,

(1) during removal or installation, the terminals of discharge cartridges should be grounded or shorted.

(2) before connecting cartridge terminals to the electrical system, the system should be checked with a voltmeter to see that no voltage exists at the terminal connections.

Regarding the above statements,

What method is used to detect the thermal discharge of a built-in fire-extinguisher system?

The thermal switches of a bimetallic thermal-switch type fire-detection (single-loop) system are heat-sensitive units that complete circuits at a certain temperature. They are connected in

Refer to Figure 21. Using the chart, determine the temperature range for a fire-extinguishing agent storage container with a pressure of 330 psig. (Consider 330 psig for both minimum and maximum pressure).

Refer to Figure 21. Determine what pressure is acceptable for a fire-extinguisher when the surrounding area temperature is 33 degrees F. (Rounded to the nearest whole number.)

On a periodic check of fire extinguisher containers, the pressure was not between minimum and maximum limits. What procedure should be followed?

In some fire-extinguishing systems, evidence that the system has been intentionally discharged is indicated by the absence of a

If a fire extinguisher cartridge is removed from a discharge valve, it should be

Which of the following are fire precautions which must be observed when working on an oxygen system?

Which fire-extinguishing agent is considered to be the least toxic?
