Question 1

What is the minimum water supply duration required for a hydraulically designed wet-pipe sprinkler system in an Ordinary Hazard Group 2 occupancy per NFPA 13?

Accepted Answer

60 minutes

Answer

NFPA 13 requires a 60-minute water supply duration for Ordinary Hazard Group 2 occupancies with hydraulically designed systems.

Question 2

In a pre-action sprinkler system, what combination of events must occur before water discharges through an open sprinkler head?

Accepted Answer

Detector activates and pre-action valve opens

Answer

In a standard pre-action system, a detection device activates the pre-action valve to fill the piping with water, then the sprinkler fuses to discharge.

Question 3

Which NFPA standard governs the installation of foam-water sprinkler systems?

Accepted Answer

NFPA 16

Answer

NFPA 16 is the Standard for the Installation of Foam-Water Sprinkler and Foam-Water Spray Systems.

Question 4

A deluge system differs from a pre-action system primarily because a deluge system:

Accepted Answer

Has all sprinkler heads open and discharges immediately on valve opening

Answer

Deluge systems use open (unloaded) sprinkler heads so water discharges simultaneously from all heads when the deluge valve opens.

Question 5

For a clean agent fire suppression system using FK-5-1-12 (Novec 1230), what is the primary mechanism by which it suppresses fire?

Accepted Answer

Physical cooling and some chemical inhibition

Answer

FK-5-1-12 suppresses fire primarily through physical heat absorption (cooling) with a minor chemical inhibition contribution.
