During inspection of a clean agent suppression system, the technician finds the agent cylinder weight is 5% below the listed weight. What action is required?
Answer: Recharge or replace the cylinder immediately
NFPA 2001 requires cylinders with agent loss exceeding 5% of net weight or a pressure loss of more than 10% to be recharged or replaced.
What is a 'four-year internal inspection' requirement under NFPA 25, and to which system does it primarily apply?
Answer: Internal pipe inspection of dry and preaction systems for microbiologically influenced corrosion
NFPA 25 requires internal inspection of dry and preaction system piping every 4 years to check for corrosion, scale, and microbiologically influenced corrosion (MIC).
A technician performing a semi-annual fire pump test records a churn (no-flow) pressure reading. What is the acceptable variance from the original acceptance test data?
Answer: Up to 10% variation is acceptable
NFPA 25 allows up to a 10% decrease in pump pressure from the original acceptance test before requiring corrective action.
When is a 'witnessed test' by the AHJ typically required for a fire protection system?
Answer: During installation acceptance testing and after major modifications
The AHJ typically witnesses acceptance tests after new installation or major modifications to verify the system meets code requirements before occupancy.
A technician inspects a fire department connection (FDC) and finds the swivel coupling is seized and will not rotate. What is the correct action?
Answer: Tag the FDC out of service and arrange for repair
A seized FDC swivel prevents firefighters from quickly connecting their hose, making it a critical deficiency requiring immediate repair.
Under NFPA 72, which test is used to verify that a manual pull station sends a correct alarm signal to the fire alarm control unit?
Answer: Functional test
A functional test of a manual pull station requires actually operating the device to confirm it transmits a valid alarm signal to the control unit.
When a fire sprinkler system is taken out of service for more than 10 hours in a 24-hour period, what must the technician ensure is in place?
Answer: An approved fire watch and notification to the AHJ and insurance carrier
NFPA 25 and most codes require a fire watch and notification to the AHJ and insurance carrier when a system is impaired for more than 10 hours in a 24-hour period.
