An inspector performing a quarterly inspection of a fire pump notices the jockey pump is cycling on and off repeatedly. What does this indicate?
Answer: There is a leak in the fire protection system piping
A jockey pump that cycles on and off repeatedly indicates a leak in the fire protection system that is causing pressure loss.
Which sprinkler listing organization is recognized by NFPA 13 for listing and labeling fire sprinklers used in the United States?
Answer: Any nationally recognized testing laboratory (NRTL)
NFPA 13 requires sprinklers to be listed by a nationally recognized testing laboratory (NRTL), which includes UL, FM Approvals, and others.
During a fire alarm system inspection per NFPA 72, which device requires functional testing every 6 months rather than annually?
Answer: Duct smoke detectors
NFPA 72 requires duct smoke detectors to be tested semi-annually (every 6 months) due to their critical role in HVAC shutdown.
A fire protection inspector finds that a standpipe system's hose valve outlets have been blocked by stored materials. Under NFPA 25, this is classified as what type of deficiency?
Answer: Critical deficiency requiring immediate correction
Blocked hose valve outlets that prevent fire department or occupant use represent a critical deficiency requiring immediate correction under NFPA 25.
What is the maximum permitted pressure drop across a backflow preventer installed in a fire sprinkler system water supply per NFPA 13?
Answer: The actual pressure drop must be included in hydraulic calculations
NFPA 13 requires that the actual pressure loss through a backflow preventer be included in the hydraulic calculations rather than using a fixed maximum.
When reviewing as-built drawings for a completed sprinkler installation, what is the primary purpose of verifying the hydraulic design area location?
Answer: To confirm adequate water supply for the most demanding sprinkler area
The hydraulic design area represents the most hydraulically demanding zone, and verifying it confirms the water supply can meet demand under worst-case conditions.
During an NFPA 25 five-year obstruction investigation, a technician flushes a sprinkler system main and finds significant debris including scale and biological growth. What must occur before the system is returned to service?
Answer: An internal pipe inspection and obstruction removal must be completed
When significant obstruction material is found, NFPA 25 requires a complete internal investigation and removal of all obstruction material before returning the system to service.
