Annual Inspection Deficiencies at an Occupied School
A 60,000 sq ft middle school in Greensboro, North Carolina, has a 15-year-old addressable fire alarm system with 36 spot-type smoke detectors, 12 duct smoke detectors, and a central station connection. During the annual inspection, four spot-type smoke detectors fail the manufacturer’s sensitivity test; one duct detector shows a dirty-chamber trouble; and the panel logs an intermittent ground fault on a signaling line circuit. The maintenance log is missing the previous two annual inspection records, and the school says it cannot afford repairs until summer, about 10 weeks away. The building is occupied for classes, after-school programs, and weekend community events. The AHJ has not been notified of any impairment. The contractor must decide what can be scheduled and what cannot wait, and how to document the findings.
1. Rank the deficiencies by urgency and state which cannot wait until summer. Explain the life-safety reasoning.

The intermittent ground fault should be investigated first because it can indicate damaged or wet wiring on a signaling line circuit and can escalate to loss of a circuit or the whole system. The four out-of-range smoke detectors come next because they may not respond within the listed sensitivity range; they must be cleaned, recalibrated, or replaced and retested. The dirty duct detector is also urgent because it can cause false alarms or fail to sample air, and it may be interlocked to shut down air handling. The missing records are a documentation deficiency but do not by themselves create an immediate impairment. A blanket 10-week delay is risky because the school is occupied for classes and weekend events. If any portion of the system is impaired, the contractor should notify the AHJ and owner in writing, tag the panel, and recommend a fire watch or other approved mitigation until repairs are complete. The AHJ may permit staged repairs, but the contractor should not decide unilaterally to leave life-safety deficiencies open.
2. What impairment procedures apply if repairs require disabling the system during school hours?
Read the worked answer
Before disabling anything, notify the AHJ, the building owner or school official, and the central station. Place the central station account on test to prevent a false dispatch. Provide occupant notification and post signs at entrances. Implement a fire watch with trained personnel if the system or a protected area will be out of service, and document the times, areas, and personnel. Tag the panel and any out-of-service devices. Restore the system as soon as possible, then perform a functional test of the affected circuits and devices and confirm signals at the central station. Notify the AHJ when protection is restored. The contractor should not allow the school to continue using an impaired system without an approved mitigation plan. Document all notifications and restoration tests in the inspection record.
3. What records must be kept, and what should appear on the inspection report for these findings?
Read the worked answer
The inspection report should list each deficiency, the device or circuit involved, the test method, the measured sensitivity or trouble condition, and the recommended correction. It should identify the four out-of-range smoke detectors and the dirty duct detector, describe the ground fault symptoms and panel history, and note that the previous two annual records were unavailable. The contractor should provide the owner with a signed report, a list of devices tested, and the test results. Records of completion, inspection and testing, sensitivity testing, battery tests, and central station tests should be retained and made available to the AHJ for the required period. Missing prior records should be treated as a finding, not ignored. The final documentation should show that corrections were made and retested, with dates and signatures.
