Which document governs the inspection, testing, and maintenance of water-based fire protection systems?
Answer: NFPA 25
NFPA 25 is the standard for the inspection, testing, and maintenance of water-based fire protection systems.
A dry pipe valve is designed to hold back water until:
Answer: Air or nitrogen pressure in the system drops due to sprinkler activation
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.
What is the purpose of a main drain test on a sprinkler system?
Answer: Verify adequate water supply pressure and detect obstructions
The main drain test verifies that the water supply has adequate pressure and flow, and can indicate potential obstructions in the supply piping.
In a pre-action sprinkler system, water enters the pipes when:
Answer: The detection system activates the pre-action valve
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.
Which sprinkler classification has the highest heat-responsive element temperature rating?
Answer: Extra high (325-375°F)
Extra high temperature-rated sprinklers (325-375°F) are used in areas with normally high ambient temperatures such as near heating equipment.
What is the minimum required flow rate for a fire hose standpipe Class III system outlet?
Answer: 250 gpm
NFPA 14 requires a minimum 250 gpm flow at the hydraulically most remote Class III standpipe outlet.
