How Often Should a Fire Alarm Be Serviced?
Commercial and non-domestic fire alarm systems are normally serviced by a competent fire alarm engineer at least every six months, with regular user tests carried out between engineer visits.
Short answer
For most commercial and non-domestic fire alarm systems, professional inspection and servicing is normally carried out at least every six months by a competent fire alarm engineer.
This is separate from the regular user tests that should be carried out by the responsible person or someone acting on their behalf. User tests help identify obvious problems between engineer visits, but they do not replace proper inspection and servicing.
The exact maintenance arrangement should take account of the building, fire risk assessment, system type, occupancy, insurer requirements, logbook records and any recommendations from the installer or maintenance provider. If you are responsible for a building, you should make sure the fire alarm is properly maintained and records are kept.
Sanders Secure provides fire alarm servicing and maintenance for commercial and managed premises across Plymouth and the surrounding area.
Why fire alarm servicing matters
A fire alarm is a life safety system. It is there to warn people early, support safe evacuation and alert the responsible person to a possible fire condition.
A system can look normal from the outside while still having issues. Detectors can become contaminated, call points can be damaged, sounders can fail, batteries can weaken, zones can be disabled, and fault messages can be missed or left unresolved.
Routine servicing helps confirm the system is still suitable, operational and being looked after properly. It also gives the responsible person a record that the fire alarm has been checked by a competent person.
How often should different fire alarms be checked?
The correct arrangement depends on the premises and the system. These are sensible general guidelines.
Weekly user tests
A regular user test helps confirm that the alarm can be operated and that the sounders activate. These checks should be recorded in the fire alarm logbook.
Engineer servicing
For many commercial fire alarm systems, professional inspection and servicing is normally carried out at least every six months by a competent fire alarm engineer.
Higher-risk or complex sites
Some sites may need more frequent checks, depending on the risk assessment, building use, system complexity, faults, false alarm history or insurer requirements.
Important: This is general guidance. The responsible person should follow the fire risk assessment, logbook requirements, insurer requirements, maintenance recommendations and any formal advice given for the specific premises.
What is checked during a fire alarm service?
The exact checks depend on the fire alarm system, the building and the agreed maintenance arrangement. A proper service should look at the operation, condition and records of the system.
- Checking the fire alarm control panel.
- Reviewing faults, disablements and warning messages.
- Checking the fire alarm logbook where available.
- Testing a suitable proportion of call points and detectors.
- Checking sounder operation where appropriate.
- Checking visual alarm devices where fitted.
- Checking battery condition and charging where applicable.
- Checking manual call points for damage or obstruction.
- Checking detector condition and obvious contamination issues.
- Checking zones, labelling and basic system operation.
- Checking interfaces where applicable and safe to test.
- Identifying faults, defects or recommendations.
- Recording the visit and advising the responsible person.
- Confirming whether further remedial work is needed.
Some tests may need to be planned carefully so they do not cause unnecessary disruption, especially where alarms are linked to other systems, monitoring, access control, plant, lifts, smoke control or other building services.
User testing and servicing are not the same thing
User testing is normally a simple routine check carried out by the responsible person, site manager or nominated person. It helps confirm that the alarm operates and that people in the building can hear it.
Professional servicing is more detailed. It involves a competent fire alarm engineer inspecting and testing the system, checking faults, reviewing parts of the installation and advising on any defects or maintenance issues.
Both are important. A weekly test does not replace periodic servicing, and periodic servicing does not remove the need for regular user checks between visits.
Signs your fire alarm needs attention
Do not wait for the next planned service if the fire alarm is showing signs of a problem.
The panel is showing a fault
A fault light or fault message should be investigated. It may relate to a zone, detector, sounder circuit, battery, mains supply, earth fault or other system issue.
Call points or detectors are damaged
Damaged, obstructed or missing devices should be addressed promptly, especially in escape routes and higher-risk areas.
False alarms keep happening
Repeated false alarms should be investigated. They can lead to complacency, disruption and loss of confidence in the system.
The system has been altered
Building work, layout changes, new rooms, tenant changes or changes in use may affect whether the fire alarm remains suitable.
Records are missing
Missing service records, logbook entries or unclear maintenance history can make it harder to demonstrate that the system has been looked after.
The last service date is unknown
If nobody knows when the system was last serviced, it is sensible to arrange an inspection and restart proper maintenance records.
Who is responsible for arranging fire alarm servicing?
In many commercial or managed buildings, the responsible person, duty holder, landlord, managing agent or business owner will need to make sure fire safety systems are maintained appropriately.
The exact responsibility can depend on the building, lease, management arrangement and fire safety duties. If you are unsure who is responsible, check your fire risk assessment, lease or management documents and seek competent advice where needed.
From a practical point of view, someone should be clearly responsible for arranging maintenance, keeping records, dealing with faults and making sure remedial actions are not ignored.
