Annual Inspection Findings at a Sprinklered Hotel
A six-story, 122-room hotel has a 12-year-old addressable system with full sprinkler protection. During today's annual inspection the following is recorded: the third-floor elevator lobby smoke detector is found inside a plastic bag left by painters three months ago; the waterflow switch at Riser 3 reports at 105 seconds; the tamper switch on the Riser 3 OS&Y valve does not report at all after a recent valve rebuild; a corridor horn/strobe measures 78 dBA where the average ambient is 74 dBA; one of four duct detectors produces no alarm and no unit shutdown; and the panel history shows three supervisory points bypassed for the past 60 days. The maintenance man says he can fix the tamper switch himself with a spare he has, and asks you to 'sign the report so we can close the permit.' The property manager wants to know which items are urgent.
1. Separate the findings into impairments and deficiencies, and state what must be done before you leave the site.

Impairments - the building is not being protected right now:
- The bagged elevator lobby detector is a defeated detection point, and if that detector participates in elevator recall, the recall function is dead as well.
- The tamper switch that does not report means the Riser 3 control valve can be shut with no indication anywhere; that is loss of sprinkler supervision.
- Three supervisory points bypassed for 60 days is a deliberate, undocumented defeat of supervision and should be treated as a management failure, not a device failure.
Deficiencies requiring correction:
- Waterflow at 105 seconds exceeds the 90-second maximum for a retard-type switch; adjust or replace, then retest.
- 78 dBA against 74 dBA ambient fails the roughly 15 dBA-above-average-ambient criterion for public mode (about 89 dBA here, and never below the 65 dBA floor). The device may be underpowered, mis-tapped, or the ambient may have risen since design.
- The failed duct detector means smoke can be distributed through the building and the associated unit's shutdown is gone; repair it, or take the unit out of service.
Before leaving: unbags and test the detector, restores tamper supervision and verifies it at the panel and the supervising station, clears and verifies every bypass, retests waterflow after adjustment, and documents what could not be corrected. Any function still impaired gets written notice to the owner and AHJ plus a discussion of a fire watch.
2. How should the impairment and the findings be documented and communicated?

Documentation is the deliverable that survives the job.
- Record of Inspection and Testing: device identifier, location, test method, result, and pass/fail for every item tested. Note explicitly what was not tested and why.
- Deficiency list with the code basis and a priority for each item, separate from cosmetic observations, so the owner can budget and the AHJ can triage.
- Impairment notice at the panel and at the affected riser, with date, time, system affected, and the person notified.
- Written notification to the owner and the AHJ for anything left impaired, including the recommendation for a fire watch or other compensating measure where the lost function is significant.
- Photographs of the bagged detector with the date visible - it is evidence of a condition you found, not one you created.
- Panel history export before the log rolls over, since the bypass history is the record of how long the system was degraded.
- Reinspection date for anything deferred.
Retain the records and keep them available to the AHJ on request. The purpose is not paperwork: it is proving what you found, what you fixed, and what the owner was told to fix, which is exactly the line that protects both the contractor and the guests.
3. The maintenance man offers to repair the tamper switch himself and asks you to sign the report so the permit can close. What is your response?
Read the worked answer
Decline, in writing, and explain why.
You can only certify testing you performed on work you can verify. Signing a report that closes out a repair you did not make or observe is a false statement to the AHJ, and it transfers the liability for the switch, the valve, and any loss that follows onto your signature.
What to do instead:
- Record the tamper switch as an open deficiency on today's report and leave the impairment documented.
- Tell the owner that a replacement switch installed by maintenance staff, without a licensed contractor, has no test record and no basis for certification.
- Offer the correct path: your firm (or another properly licensed and registered alarm contractor) replaces the switch, verifies the signal at the panel and at the supervising station, and issues a new test record for that point. Then the permit closes on real evidence.
- Note that in Illinois alarm work is licensed work - an agency license through the state and registration cards for the employees performing it - so the maintenance man doing the repair is also a licensing exposure for the owner.
- If the owner presses, restate the position in an email and copy the AHJ contact if the findings are serious.
Goodwill matters here: offer to schedule the repair quickly and to handle the paperwork, so the refusal reads as professional discipline rather than obstruction.
