Procedures for Restoring a System to Service Flashcards

After a sprinkler system is restored following an impairment, what must the impairment coordinator do with the out-of-service tag?

Answer: Remove the tag and file it with the impairment documentation as a record of the completed impairment

After restoration, the out-of-service tag must be removed and filed with the impairment documentation as a permanent record. Leaving the tag in place would create false impairment status.

During restoration of a fire alarm system following a planned impairment, a smoke detector in the affected zone fails its functional test. What must happen before the system can be declared restored?

Answer: Replace or repair the failed detector, retest it, and confirm the system passes all zone tests before declaring the system fully restored

Any device that fails functional testing must be repaired or replaced and retested before the system can be declared fully restored. Leaving a failed detector creates a detection gap.

How should the F-01 fireguard document the termination of the fire watch in the logbook?

Answer: Record the exact time of fire watch termination, confirmation received from the impairment coordinator, system restoration status, and the fireguard's signature with CoF number

The final logbook entry must include: exact termination time, confirmation of system restoration from the impairment coordinator, system status at time of termination, and the fireguard's signature and CoF number.

What is the purpose of a 'main drain test' following restoration of a wet pipe sprinkler system?

Answer: To verify adequate water supply pressure and flow to the system by opening the main drain and measuring residual pressure

A main drain test verifies that the water supply can deliver adequate pressure and flow to the sprinkler system. The test measures static and residual pressure to confirm the supply is unimpaired.

After restoring a fire alarm system, the monitoring company reports that signals from the restored zone are coming through with an incorrect zone identifier. What does this indicate and what must be done?

Answer: There is a programming or wiring error in the alarm system that must be corrected before the system can be declared fully restored

Incorrect zone identifiers at the monitoring company indicate a programming or wiring error. This means FDNY would be given wrong location information during an emergency — the error must be corrected before restoration is complete.

A building manager asks the F-01 fireguard to confirm that the fire watch is terminated and to sign the final logbook entry, but the impairment coordinator has not yet confirmed system restoration. What should the fireguard do?

Answer: Refuse to sign a restoration confirmation without explicit confirmation from the impairment coordinator that the system is fully restored

The fireguard must refuse to sign a restoration confirmation without direct confirmation from the impairment coordinator. Signing prematurely would falsely document a system as restored when it may not be.
