Annual ITM Interval Conflict at a Mixed-Occupancy Building
A mixed-use building has a fire alarm system installed in 2015. The property manager's maintenance contract specifies annual testing of all initiating devices and notification appliances. The AHJ's records show that the last inspection was 14 months ago. During a walkthrough, the AHJ finds: two smoke detectors with no test record, one notification appliance circuit with a failed appliance, and a panel with a silences audible-only trouble that was never logged. The manager argues the annual contract satisfies the code and that the failed appliance is a minor cosmetic issue. The building contains a daycare on floor 1 and offices above.
1. Identify the ITM deficiencies and their significance.
Read the worked answer
Deficiencies: (1) Interval - the last inspection was 14 months ago, exceeding the required annual interval; the contract's annual schedule does not cure the missed inspection. (2) Two smoke detectors lack test records, so their operability is unverified; they must be tested and documented. (3) A failed notification appliance is not cosmetic - it reduces the audibility/visibility coverage of the evacuation signal in an occupied area, which is a life-safety deficiency. (4) An unlogged trouble indicates the system was not monitored and records were not maintained; trouble signals must be investigated and documented.
The daycare occupancy raises the stakes: occupants may need assistance to evacuate, so notification coverage and reliable detection are critical. The AHJ should treat the failed appliance and untested detectors as deficiencies requiring correction, not deferrals.
2. What should the AHJ require, and by when?
Read the worked answer
Require a written correction plan with dates: immediate testing and documentation of the two detectors; repair or replacement of the failed notification appliance and a verification test of the affected circuit; investigation and logging of the trouble condition; and a complete inspection and test of the system to bring it back into the required interval. The AHJ should require the missed annual inspection to be completed promptly and the records submitted. Because of the daycare, the failed appliance and any impaired notification should be addressed first, with interim measures (such as a fire watch or temporary notification) if the impairment cannot be corrected immediately. Final acceptance should be conditioned on submitted test records signed by the tester.
