CFPS Detection and Alarm Systems 5

Question 1

A mass notification system (MNS) integrated with a fire alarm system must give priority to:

Accepted Answer

Fire alarm signals over all other MNS messages

Answer

NFPA 72 requires that life-safety fire alarm signals take priority over MNS messages to ensure occupants always receive fire evacuation instructions first.

Question 2

The Common Indicating Circuit (CIC) in a multiplex fire alarm system is used to:

Accepted Answer

Carry multiple alarm signals over a single pair of conductors using time-division or frequency-division multiplexing

Answer

A multiplex or signaling line circuit (SLC) transmits data from many devices over shared conductors by assigning each device a unique address and using multiplexing protocols.

Question 3

In the context of NFPA 72, a 'protected premises' fire alarm system is one that:

Accepted Answer

Is located at and serves the property where the protected area exists

Answer

A protected premises system (formerly local system) is installed at and serves the property itself, as opposed to supervising station or public emergency alarm reporting systems.

Question 4

Which detector type is BEST suited for detecting a fast-flaming fire involving flammable liquids in an open outdoor environment?

Accepted Answer

UV/IR flame detector

Answer

UV/IR flame detectors respond directly to the radiant energy spectrum of open flames and are not confused by wind or ambient dilution of smoke, making them ideal for outdoor flammable liquid hazards.

Question 5

An end-of-line (EOL) resistor in a conventional fire alarm initiating device circuit provides which function?

Accepted Answer

Allows the panel to supervise the circuit for open-circuit faults

Answer

The EOL resistor creates a known current flow that the panel monitors; if the circuit opens (wire break or device removed), the current changes and the panel generates a trouble signal.
