Day 364: the AHJ is on the calendar, the battery passed last year's one-hour test, the donor antenna might be drifting, and nobody has opened the BDA logs in eight weeks. ERRCS portfolios that prove their own NFPA 1221 compliance — donor signal health, battery 1-hour runtime, BDA telemetry and sealed evidence packets ready for the AHJ on day 364, every year.
Indicative benchmarks from ERRCS operator interviews — your portfolio's numbers will differ. Methodology on request.
Drop in next to your existing BDA RMS and battery management — read-only at first, write-scope when the runbooks earn it.
Downlink reception level sampled per band, alarmed on threshold drift, correlated against external RF events.
Continuous battery profiling, runtime projection, capacity drift alarms — alerts before AHJ visit, not after.
Grid tests, battery logs, donor signal continuity and BDA configuration audits — assembled live, dated, signed.
Give the AHJ inspector a direct view, scoped to one building and one inspection window. Revoke instantly.
ObservOne picks up a sustained −3 dB drop on the public-safety band donor signal — three consecutive 5-minute samples below threshold, not a single-reading blip.
Donor antenna alignment delta detected against last week's sweep. Battery cycle nominal. Runtime projection still well above the one-hour rule. Annual test due in 14 days — schedule the alignment fix this week.
Annual test packet now drafted with the corrected sweep included. Battery log appended. Change-of-condition affidavit signed and dated for SF-AHJ Q3 submission.
30 minutes with a solutions engineer. We'll load a sandbox tenant with anonymised buildings that match your portfolio — BDA vendors, battery mix, AHJ jurisdictions. NDA-friendly.
