A thorough annual inspection isn’t just a paperwork exercise — it’s the difference between a building that passes Reg-4 on first walk and one that gets tagged. After 30 years and ten thousand-plus inspections, here’s the checklist BEC’s senior techs follow.

-
Documentation prep
Before the truck rolls, pull the as-builts, the last inspection report, the riser diagram, and the device inventory. Half the inspection failures we see come from missing documentation, not failed devices.
-
Visual inspection walk
Walk every floor. Look for blocked devices, painted-over smokes, missing covers, water damage on horns, and signage that doesn’t match the riser. Photograph anything questionable — the AHJ will ask.
-
Battery and power test
Verify standby battery capacity against the load calc. NFPA 72 requires 24 hours standby + 5/15 minutes alarm. If the batteries are over 4 years old, replace them — don’t argue with chemistry.
-
Functional device test
Every initiating device, sensor by sensor. Smoke detectors with canned smoke, heat detectors with the right test instrument, manual stations with the correct key, duct detectors with a remote test switch.
“If you’re testing more than 10 devices an hour, you’re not testing — you’re checking boxes.”

Notification appliance test
dB readings at every audibility-required location, strobe sync verification, voice intelligibility (STI) checks where required.
-
Smoke detector sensitivity
NFPA 72 §14 requires sensitivity testing on every smoke detector at intervals defined by manufacturer. Edwards Signature/Optica detectors self-report drift — read the trouble log, don’t just trust the panel.
-
Sprinkler & flow switch interface
Trip every flow switch and tamper. Verify the panel shows the right zone, with the right device address, and that the central station receives the signal within 90 seconds.
-
Smoke control interface
If the building has smoke control, run the matrix test. This is where buildings most often fail Reg-4 — the fans run, but the dampers don’t position correctly under fault.
-
ERRCS check
Verify BDA status, donor antenna integrity, battery backup, and signal strength at the same grid points used at acceptance.
-
Reporting & AHJ filing
The report has to match the AHJ’s preferred format on the first submittal. LAFD, OCFD, and SDFD all want slightly different things — get this right and you don’t make a second trip.
