F80 F80 Fire Safety Systems 5

Question 1

A voice evacuation system is required in which type of building under NFPA 72?

Accepted Answer

High-rise buildings over 75 feet in height

Answer

NFPA 72 and IBC require voice/alarm communication systems in high-rise buildings exceeding 75 feet in height.

Question 2

What is the primary difference between a smoke control system and a smoke exhaust system?

Accepted Answer

Smoke control maintains pressure differentials; exhaust mechanically removes smoke from a space

Answer

Smoke control systems use pressurization to prevent smoke migration, while exhaust systems mechanically remove smoke from a specific area.

Question 3

In a fire alarm system, what does the term 'initiating device circuit' (IDC) refer to?

Accepted Answer

The circuit that connects detectors, pull stations, and other input devices to the FACP

Answer

An IDC is the wiring circuit that carries signals from initiating devices (detectors, pull stations) to the fire alarm control panel.

Question 4

Which NFPA standard specifically covers the inspection, testing, and maintenance of water-based fire protection systems?

Accepted Answer

NFPA 25

Answer

NFPA 25 is the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems.

Question 5

What is the purpose of an 'end-of-line' (EOL) resistor in a supervised fire alarm circuit?

Accepted Answer

To allow the FACP to detect open or short circuits on the initiating device circuit

Answer

An EOL resistor completes the circuit at a specific resistance so the FACP can continuously monitor for wiring faults.
