A commercial fire alarm should normally be tested every week. For a typical non-domestic fire alarm, the routine user test normally involves operating a manual call point, using a different call point on successive tests. The system should also be inspected and serviced periodically by a competent fire alarm specialist; government guidance commonly describes this as six-monthly servicing.
The weekly test and the engineer's service are different. The weekly test is a simple operational check. Professional servicing is a much more detailed inspection of the system, its condition and any faults.
In short: test the fire alarm weekly, record the result, investigate faults and unwanted alarms, and arrange competent periodic servicing. The exact regime should reflect the premises, fire risk assessment, system and applicable standards.
Fire alarm testing frequency at a glance
- Daily / routinely: check the control panel for unexpected fault indications as part of normal site management.
- Weekly: carry out the routine user test, normally using a manual call point and rotating the point used.
- After each test: record the result and any fault or follow-up action in the fire alarm logbook.
- Typically every six months: arrange inspection, testing and preventive maintenance by a competent fire alarm specialist.
- As faults or unwanted alarms occur: record and investigate them rather than waiting for the next planned service.
Why is a commercial fire alarm tested weekly?
A fire alarm can remain quiet for long periods, so routine testing provides a regular check that an alarm signal can be initiated and that the system responds as expected. Current government fire-safety guidance for non-domestic premises recommends weekly testing.
For an electrical system, this normally means operating a manual call point with the correct test key. A different call point should be used on successive weeks rather than repeatedly testing the same device.
Is weekly fire alarm testing a legal requirement?
The Regulatory Reform (Fire Safety) Order 2005 requires relevant fire-safety equipment to be subject to a suitable system of maintenance and kept in efficient working order and good repair. Government guidance then sets out recognised testing and maintenance arrangements, including weekly testing of fire-warning systems.
BS 5839-1:2025 is the current British Standard code of practice for fire detection and fire alarm systems in non-domestic premises. It superseded the 2017 edition in April 2025 and provides the detailed framework used for design, installation, commissioning and maintenance.
An existing system designed to an earlier edition does not automatically need replacing simply because the standard has been updated. Alterations, maintenance decisions and new work should, however, be assessed against the current requirements and the circumstances of the building.
How should the weekly fire alarm test be carried out?
Follow the system instructions and your site's fire-safety procedure. For a typical commercial system, a sensible routine is:
- Tell the relevant people. Staff, reception, security or tenants should know that a planned test is taking place.
- Check monitoring arrangements. If the alarm is connected to an Alarm Receiving Centre (ARC), follow the agreed test procedure so the test does not create an unwanted response.
- Operate a manual call point. Use the correct test key and rotate the call point used from week to week.
- Confirm the expected response. Check that the panel registers the activation and that the warning is received as expected.
- Reset the system. Make sure the panel returns to normal, any isolations are restored and monitoring is put back into service.
- Record the test. Note the date, time, call point, result, person carrying out the test and any fault or action required.
The weekly test is not intended to reproduce an engineer's service. It is a routine check that helps identify obvious problems between maintenance visits.
Who can carry out the weekly test?
The routine test does not normally require a fire alarm engineer. It can be carried out by a suitably instructed person who understands the test procedure, how to reset the system, any monitoring arrangements and what to do if something goes wrong.
Professional inspection, servicing and fault diagnosis should be undertaken by someone with the appropriate fire alarm competence.
How often should a commercial fire alarm be professionally serviced?
Government guidance commonly recommends six-monthly servicing and preventive maintenance by a competent person with specialist knowledge of fire-warning and automatic detection systems.
The appropriate maintenance programme can also depend on the premises, fire risk assessment, system condition, manufacturer's requirements, fault history and any specific insurer or authority requirements.
SPS Technical provides commercial fire alarm maintenance and is BAFE SP203-1 certificated for relevant fire detection and alarm work.
What should be recorded in the fire alarm logbook?
Keep the record useful rather than treating it as a tick-box exercise. It should show routine tests, service visits, faults, unwanted alarms, system isolations, repairs, alterations and outstanding actions.
Good records make patterns easier to spot. Three apparently minor faults over several months can look very different when they are viewed together rather than as separate engineer visits.
What if the weekly test fails?
Do not simply record a failure and wait until the next service visit. Record what happened and follow the site's fault and escalation procedure.
- If a call point does not activate the alarm, arrange appropriate investigation.
- If the warning cannot be heard or perceived in part of the premises, consider whether changes to layout, occupancy or background noise have affected the system.
- If the panel shows a persistent fault, do not allow it to become accepted as the normal condition.
- If a monitored signal is not received as expected, check the ARC test procedure and escalate the signalling issue.
Where a fault affects the building's fire precautions, the Responsible Person should consider whether temporary measures are required until the problem is resolved.
False alarms are part of the maintenance picture
Repeated unwanted alarms should be recorded and investigated. They may be associated with detector selection, steam or cooking fumes, dust, environmental contamination, building works, device condition, system faults or site processes.
Frequent false alarms are not only disruptive. They can be a useful warning that the system, its environment or its maintenance arrangements need attention. The answer is not automatically to reduce detection; the cause should be understood first.
What about monitored fire alarms?
If a fire alarm sends signals to an ARC or other monitoring facility, the weekly test needs an agreed procedure. The monitoring provider may need to place the connection on test before activation and confirm that normal monitoring has been restored afterwards.
A fire alarm that operates correctly inside the building and a signalling path that successfully reaches the monitoring centre are related but separate things. Both need to work as intended. See our guide to fire and security monitoring.
When should the wider fire alarm system be reviewed?
Routine servicing should not mean maintaining the same arrangement indefinitely without considering whether it still suits the building. A technical review is sensible when there are repeated faults or false alarms, incomplete service records, changes to the building or occupancy, obsolete equipment, difficulty obtaining parts, or significant remedial expenditure.
If you have inherited an existing system or are considering changing provider, a structured fire alarm takeover can establish the system condition, outstanding defects, monitoring arrangements and maintenance baseline before future work is agreed.
Commercial fire alarm testing: the essentials
- Test the fire alarm weekly.
- Rotate the manual call point used on successive tests.
- Record every test and any fault found.
- Follow the agreed procedure for monitored systems.
- Investigate repeated faults and unwanted alarms.
- Arrange competent periodic servicing, commonly at six-month intervals for commercial systems.
- Review the system when the building changes or reliability begins to deteriorate.
SPS Technical supports commercial organisations across Yorkshire, Lincolnshire and the Humber with fire alarm systems, planned maintenance, fault investigation, monitoring and system takeovers.
