During hydrostatic testing of a sprinkler system, what is the minimum test pressure required per NFPA 13 when the system working pressure does not exceed 150 psi?
Answer: 200 psi for 2 hours
NFPA 13 requires hydrostatic testing at 200 psi for 2 hours when the system working pressure does not exceed 150 psi.
Which document serves as the primary reference for the inspection, testing, and maintenance of water-based fire protection systems in the US?
Answer: NFPA 25
NFPA 25 is the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems.
A fire inspector discovers that a sprinkler head has been painted over by building maintenance staff. What is the correct action?
Answer: Replace the sprinkler head immediately
Painted sprinkler heads must be replaced because paint can alter the thermal response characteristics and obstruct the deflector.
What frequency does NFPA 25 require for the inspection of wet pipe sprinkler system control valves in a supervised system?
Answer: Monthly
NFPA 25 requires monthly inspection of control valves in supervised systems to verify they are in the open position.
During acceptance testing of a fire alarm system, a technician performs a full-load test. Which condition must be verified?
Answer: Battery backup operates all devices for 24 hours in standby plus 5 minutes alarm
NFPA 72 requires secondary power capacity to support 24 hours of standby followed by 5 minutes of alarm for most systems.
An inspector finds that the main drain test flow on a wet pipe sprinkler system produces a residual pressure significantly lower than previous tests. What does this most likely indicate?
Answer: A partially closed control valve upstream
A significantly lower residual pressure during main drain testing compared to historical readings typically indicates a partially closed control valve restricting water supply.
Which of the following is NOT a required item on a sprinkler system hydraulic nameplate per NFPA 13?
Answer: Name of the installing contractor's field supervisor
NFPA 13 requires the hydraulic nameplate to include design area location, required flow and pressure, and density, but not the field supervisor's name.
