NICET Water-Based Fire Protection 3

Question 1

Which document governs 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 2

A dry pipe valve is designed to hold back water until:

Accepted Answer

Air or nitrogen pressure in the system drops due to sprinkler activation

Answer

The dry pipe valve is held closed by air or nitrogen pressure in the system piping; when a sprinkler activates and pressure drops, the valve opens to allow water flow.

Question 3

What is the purpose of a main drain test on a sprinkler system?

Accepted Answer

Verify adequate water supply pressure and detect obstructions

Answer

The main drain test verifies that the water supply has adequate pressure and flow, and can indicate potential obstructions in the supply piping.

Question 4

In a pre-action sprinkler system, water enters the pipes when:

Accepted Answer

The detection system activates the pre-action valve

Answer

In a pre-action system, the detection system must first activate the pre-action valve to fill pipes with water before any sprinkler can discharge.

Question 5

Which sprinkler classification has the highest heat-responsive element temperature rating?

Accepted Answer

Extra high (325-375°F)

Answer

Extra high temperature-rated sprinklers (325-375°F) are used in areas with normally high ambient temperatures such as near heating equipment.
