If you're the Responsible Person for a business premises, one of the questions we get asked most often is simple: how often does the fire alarm actually need testing? The answer is set out in BS 5839-1, the British Standard covering fire detection and alarm systems in non-domestic premises, and it's more involved than most people expect. Get it wrong, and you're not just risking a fine, you're risking lives.
Here's what the standard actually requires, and how to stay compliant without it becoming a headache.
Weekly: a quick check anyone can do
Once a week, someone on site (usually the Responsible Person or a nominated member of staff) needs to test the system by activating one manual call point during normal working hours. It only takes a couple of minutes. The idea is simple: confirm the alarm still raises a signal at the control panel and sounds throughout the building.
Each week, use a different call point, working through the building on rotation so that every device gets tested over time. Note the date, the call point used, and the result in your fire safety log book. If the alarm doesn't sound as expected, that's a fault to report immediately, not something to leave until the next scheduled visit.
Monthly: emergency lighting
While it's a separate system, emergency lighting is usually checked alongside the fire alarm because the two go hand in hand. A monthly function test (a brief switch to battery power to confirm each luminaire operates) should be logged the same way as your weekly alarm checks.
Six-monthly: a professional service
This is the part that catches people out. BS 5839-1 requires a competent person, meaning a qualified fire alarm engineer or fire safety company, to inspect and service the system at intervals not exceeding six months. In practice, that means two visits a year, evenly spaced, rather than one annual service.
During a six-monthly visit, an engineer will typically:
- Check the condition of the control panel, detectors, call points and sounders
- Function-test a representative sample of devices (not every single one on every visit)
- Inspect standby (battery) power supplies
- Review your log book and flag any recurring faults or false alarms
- Check that any changes to the building haven't affected coverage
Over a full 12-month period, the two visits together should achieve complete functional coverage of the system, so nothing gets missed for longer than a year.
What you need to keep on record
Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must keep a fire safety log book on the premises at all times, available for inspection by a fire officer. For the fire alarm specifically, that log should show:
- Weekly call point tests, with dates and which call point was used
- Details of any false alarms, their cause, and what was done about it
- Records of every six-monthly service, including any faults found and remedial work carried out
- Any modifications made to the system
An empty or incomplete log book is one of the first things a fire officer will ask to see, and it's one of the easiest ways to fail an inspection even when the system itself is working perfectly.
Why this matters beyond compliance
A fire alarm that hasn't been properly tested is a fire alarm you can't rely on. Weekly checks catch the obvious faults; six-monthly servicing catches the ones that only show up under closer inspection, such as a battery that's losing capacity or a detector that's become less sensitive over time. Together, they're what stands between a fire alarm that works on paper and one that actually works when it matters.
