BS 5839-1
Fire alarm maintenance — the schedule
Fire alarm systems don't look after themselves. BS 5839-1 — the British Standard governing fire detection and alarm systems in commercial premises — sets out a clear routine of checks across the year. Miss them, and you're not just non-compliant: your insurance can be invalidated and the Responsible Person under the Regulatory Reform (Fire Safety) Order 2005 can be held personally liable. Here's what a compliant system actually requires.
Daily
By the Responsible Person (you or your team)
Check the panel shows normal status with no faults or warnings displayed. Takes seconds. Any fault investigated and logged.
Weekly
By the Responsible Person
Test one manual call point, rotating to a different one each week so every call point is tested over time. Confirm the alarm sounds and the panel registers the activation. Record it in the fire logbook. This is a legal requirement and one of the first things a fire officer or insurer will ask to see.
Monthly
By the Responsible Person
Test any standby generator or back-up power supply where fitted, and check batteries on systems that require it.
Every six months
By a competent engineer (us)
A professional inspection and test of the system. Roughly half the devices are tested at each visit, so across two visits a year every detector and device is checked. The engineer inspects the panel, batteries, cause-and-effect programming and all field devices, then issues a certificate.
Annually
By a competent engineer (us)
A full inspection and test of the entire system — every detector, call point, sounder and interface — verifying the system performs exactly as designed. Full certification issued for your compliance records and insurers.
The bottom line
A commercial fire alarm system needs a minimum of two professional service visits per year, on top of the in-house weekly testing. Most buildings we survey are either overdue or have no documented testing regime at all — which is exactly the gap we close.
