Question 1

Per NFPA 13, what is the maximum allowable coverage area per sprinkler head in an Ordinary Hazard occupancy?

Accepted Answer

130 sq ft

Answer

NFPA 13 limits Ordinary Hazard occupancy sprinkler coverage to 130 sq ft per head due to the higher fire potential compared to Light Hazard.

Question 2

What is the primary function of a water motor gong (mechanical alarm) on a wet pipe sprinkler system?

Accepted Answer

Provide a local audible alarm driven by water flow through the alarm valve

Answer

A water motor gong is driven by water flowing through a restricted orifice at the alarm valve, producing a loud local audible alarm without electricity.

Question 3

Which NFPA standard governs the installation of standpipe and hose systems?

Accepted Answer

NFPA 14

Answer

NFPA 14, Standard for the Installation of Standpipe and Hose Systems, covers design, installation, and maintenance requirements for these systems.

Question 4

Per NFPA 20, what performance criterion must a listed fire pump meet at churn (no-flow, shutoff) condition?

Accepted Answer

Pressure must not exceed 140% of rated pressure

Answer

NFPA 20 requires that a fire pump's pressure at churn (shutoff) shall not exceed 140% of its rated pressure to prevent overpressurizing the system.

Question 5

What substance fills the distribution piping between the dry pipe valve and the sprinkler heads in a dry pipe system under normal (standby) conditions?

Accepted Answer

Pressurized air or nitrogen

Answer

Dry pipe systems maintain pressurized air or nitrogen in the distribution piping to hold the dry pipe valve clapper closed until a sprinkler head opens.
