Fire Alarm Testing & Servicing in Surrey | SurreySec
How often should a business fire alarm be tested and serviced? A Surrey fire alarm engineer explains what to check, what to record and when to book a service.
Fire Alarm Testing vs Servicing in Surrey: What Businesses Need to Know
When did someone last test your fire alarm? And when did an engineer last service it?
These are two different questions. A weekly test checks that a selected call point can trigger the panel and alarm warning. It does not establish whether every detector, standby battery and linked function is working correctly.
I service fire alarm systems in offices, shops, clinics and blocks of flats across Surrey and South West London. A common problem I see is a system that passes its weekly test while other issues remain unnoticed.
This guide focuses on commercial fire alarm systems. It explains what each check does, what we find on service visits and how to prepare for an engineer.
How often should a commercial fire alarm be tested?
Government guidance for offices and shops recommends daily panel checks, weekly user tests and six-monthly specialist servicing.
Panel check
Timing: Daily.
Purpose: Look for fault indications, disablements or any abnormal status on the panel.
User test
Timing: Weekly.
Purpose: Operate a manual call point and check that the panel and alarm warning respond.
Professional inspection and servicing
Timing: Normally every six months.
Purpose: Inspect and test the system under a planned maintenance programme, with every detector functionally tested over a 12-month period.
Your fire risk assessment, the equipment and conditions on site may call for more frequent attention. The service provider should explain the schedule for your building and which checks are carried out at each visit.
What does the weekly fire alarm test involve?
A trained, authorised and competent person normally operates a different manual call point each week, checks the alarm response and records the result. Follow the manufacturer's instructions and the building's agreed testing procedure.
For a straightforward routine:
- Tell occupants when the planned test will take place and keep to a regular time.
- If the system is monitored, agree testing arrangements with the monitoring centre beforehand.
- Use a different call point each week and record which one was tested.
- Follow the system instructions to complete the test and reset the alarm.
- Check that the panel has returned to normal and that no unintended disablements remain.
- Confirm normal monitoring has been restored after the test, where applicable.
A successful call point test does not individually test your smoke or heat detectors. It also does not establish whether the standby batteries can provide the required backup during a power cut.
Your panel's user manual provides model-specific instructions. For example, C-TEC's XFP user manual and log book explains routine user checks and distinguishes them from specialist maintenance.
What happens during professional fire alarm servicing?
Professional servicing combines inspection with the tests scheduled under the system's maintenance programme. It should cover more than simply sounding the alarm and recording a pass.
On a typical visit, we:
- Review the log book, previous reports and false alarm history.
- Check the control panel, power supplies and standby batteries.
- Carry out the detector, call point and alarm device tests scheduled for that visit.
- Look for damaged, covered, obstructed or contaminated equipment.
- Check relevant linked functions, such as door releases, lift recall and remote monitoring, where fitted and included in the testing programme.
- Record findings, identify outstanding issues and explain any repairs needed.
Tests involving lifts or other specialist building equipment may need coordination with the relevant contractor.
The maintenance programme should ensure every detector is functionally tested over a 12-month period. The Fire Industry Association's guidance on detector testing explains this principle. The work may be organised across the scheduled visits; the report should make clear what was completed and what remains due.
Testing and cleaning must also follow the equipment manufacturer's instructions. C-TEC's detector maintenance guidance explains the role of inspection, cleaning and functional testing.
At the end of a visit, ask your engineer to explain any faults, outstanding tests or recommended work. You should know what needs attention and who is arranging the next step.
What we often find on service visits
These examples show why routine checks and professional servicing both matter:
- Standby batteries approaching or beyond their recommended replacement date. The system may operate normally on mains power while the batteries can no longer provide the required backup. Replacement should follow the manufacturer's guidance and the findings of the service checks.
- Detectors still covered by dust caps or bags after decorating or building work.
- Zones or devices left isolated after an earlier incident. These should normally produce a panel indication and be picked up during routine checks.
- New shelving, partitions or ceiling changes obstructing detection or affecting coverage.
- Detectors no longer suited to how a room is used, such as a smoke detector affected by cooking after a room becomes a kitchen.
- Repeated false alarms from the same area, recorded without the cause being investigated.
Some problems can be corrected during the visit. Others need further investigation or separately quoted remedial work. Finding the issue is the first step; arranging and recording the necessary action matters just as much.
Is fire alarm servicing a legal requirement?
Where a fire alarm is provided to meet fire safety duties in England, it must be kept in effective working order and good repair through suitable inspection, testing and maintenance.
The Home Office guide for people with fire safety duties explains the need for competent people to carry out this work and for defects to be repaired as soon as practicable.
BS 5839-1:2025 is the current British Standard for fire detection and alarm systems in non-domestic buildings. It is a code of practice rather than legislation itself. It is widely used by enforcing authorities and insurers when assessing fire safety provisions. BSI's overview explains its scope.
A fire alarm service report records the work completed on the system. It does not replace your fire risk assessment or confirm that every aspect of the building's fire safety is satisfactory.
What records should you keep?
Keep the fire alarm log book in a known, accessible location, with previous service reports available to the engineer. Record:
- The date, time and name of the person carrying out each weekly test.
- Which call point was tested and whether the expected response occurred.
- Faults, disablements, false alarms or damage reported.
- Engineer visits, repairs and outstanding work.
- The action taken to resolve each problem and when it was completed.
Specific entries are more useful than vague descriptions. For example, "Three false alarms from the second-floor kitchen in May" gives an engineer a clearer starting point than "The alarm sometimes goes off."
Name a person responsible for following up faults and outstanding work, so a problem written in the log book also results in action.
What if the panel shows a fault between services?
Report it promptly to the person responsible for the building and your fire alarm service provider. Give them the exact panel message, the location and when the problem started. A photograph of the display can help.
A fault may affect protection. Get competent advice on what it means for the building and whether temporary measures are needed while repairs are arranged.
Do not repeatedly reset the panel or isolate devices simply to stop a warning. The underlying problem still needs investigation.
If there are signs of fire, follow the building's emergency procedure and call 999 from a safe place.
