FLSD Fire Alarm Systems 4

Question 1

Under NFPA 72, what is the maximum allowable distance between smoke detectors in a corridor that is 10 feet wide?

Accepted Answer

30 feet

Answer

NFPA 72 requires smoke detectors in corridors to be spaced no more than 30 feet apart when the corridor is 10 feet wide or less.

Question 2

A fire alarm control panel (FACP) displays a 'trouble' signal. What is the FIRST action an FLSD should take?

Accepted Answer

Investigate the source of the trouble condition

Answer

A trouble signal indicates a fault in the system that requires investigation to identify and correct the problem before it compromises system reliability.

Question 3

Which type of fire alarm initiating device is MOST appropriate for detecting slow, smoldering fires in an office environment?

Accepted Answer

Photoelectric smoke detector

Answer

Photoelectric smoke detectors respond more effectively to the large smoke particles produced by slow, smoldering fires than ionization detectors.

Question 4

What does a 'supervisory' signal on a fire alarm panel indicate?

Accepted Answer

An off-normal condition exists in a supervised system

Answer

A supervisory signal indicates that a protected system (such as a sprinkler valve) is in an off-normal condition that requires attention but is not yet an alarm.

Question 5

In a high-rise building, voice evacuation systems are required to provide instructions to occupants. Which area must receive intelligible voice messages FIRST during a fire alarm?

Accepted Answer

The fire floor and the floors immediately above and below

Answer

NFPA 72 and NYC high-rise codes require that voice evacuation messages be directed first to the fire floor and the floors immediately above and below to prioritize those in greatest danger.
