Annual Inspection & Semiannual Visual

Code-anchored ERCES inspections — QR-verifiable reports your AHJ can trust.

Any building with installed BDA/ERCES equipment must be annually operational-tested per NFPA 1225 §20.3.10 and IFC §510.6, plus a semiannual visual inspection under §20.3.10.2. Zion delivers both on a predictable calendar with a certified, QR-verifiable inspection report.

What triggers annual inspection?

Any installed BDA/ERCES equipment, in any state, in any building type.

The obligation is universal

NFPA 1225 §20.3.10.2.3 requires an annual operational test of every installed ERCES/BDA system — regardless of when the system was installed, whether the current building code would newly require it, or which of the §510.1 exceptions the building might qualify for today. Installed = inspected annually.

Seven required test elements

Coverage grid re-demonstration at signal threshold (≥ –95 dBm typical)
Donor amplifier gain within ± 3 dB tolerance
Isolation ≥ 20 dB above gain
Monitored fault supervision to the FACP
Battery load test for the rated hours (typically 12 hr)
Spectrum verification (no unwanted intermod, hostile RF)
Semiannual visual inspection (V-1..V-16 items)

And it's a code default

Every recent IFC edition (2015 onward), 47 CFR §90.219 with Appendix J for FCC signal-booster compliance, and NFPA 72 Ch. 10 all mandate ongoing operational testing of installed ERCES. Missing annual inspection can trigger AHJ notice, permit hold, or Certificate-of-Occupancy revocation in aggressive jurisdictions.

The Program

A scheduled annual signal-survey, not a fire drill.

Most building owners only think about ERCES when the AHJ flags a missed inspection — and by then it's a scramble. Our annual program flips that. We pre-schedule your test on a 12-month cycle, mobilize a PCTEL-instrumented crew, and submit the AHJ-ready report before your tag expires.

For multi-building portfolios, we coordinate testing windows across all sites and consolidate reporting into a single owner deliverable.

What you receive

Pre-scheduled annual test, calendar-locked 90 days out
20-grid signal survey per IFC §510.5.3 with PCTEL instrumentation
DAQ measurements per NFPA 1225 §18.5
Battery-backup capacity test (12 / 24 hr per AHJ)
Donor antenna alignment + RSSI verification
Visual / mechanical inspection of BDA, antennas, cabling, NEMA enclosures
AHJ-ready PDF report, electronically submitted to your Fire Marshal portal
New annual inspection tag posted in your fire-control room
Deficiency report with photos, locations, and corrective recommendations
