F80 F80 Code Requirements 4

Question 1

According to NFPA 72, what type of detector is BEST suited for detecting slow, smoldering fires?

Accepted Answer

Photoelectric smoke detector

Answer

Photoelectric smoke detectors are more responsive to large-particle smoke from slow, smoldering fires, while ionization detectors react faster to fast-flaming fires.

Question 2

Under F80 code requirements, the maximum permitted sound pressure level of an audible alarm appliance in a public area is:

Accepted Answer

110 dB at 10 feet

Answer

NFPA 72 caps audible alarm output at 110 dB measured at 10 feet from the appliance to prevent hearing damage.

Question 3

When multiple fire alarm panels are networked together, NFPA 72 requires that each panel must be capable of:

Accepted Answer

Operating independently if the network connection is lost

Answer

Each networked FACU must operate independently and maintain full functionality if the network link to other panels fails.

Question 4

According to F80 code requirements, heat detectors in an unheated attic space must be rated for which temperature range?

Accepted Answer

High (250–330°F)

Answer

Unheated attic spaces can reach extreme temperatures in summer, so high-temperature rated detectors (250–330°F) are required to prevent false alarms.

Question 5

NFPA 72 defines a 'protected premises fire alarm system' as a system that:

Accepted Answer

Provides fire detection and alarm functions within a single building or complex

Answer

A protected premises fire alarm system provides detection, notification, and control functions within a specific building or campus.
