Fire System Maintenance

Inspection and Servicing

Regular fire alarm maintenance is crucial for ensuring the safety of your property and people. A well-maintained system can help detect issues early on and prevent false alarms. This may include replacing or servicing parts in order to ensure the system operates as intended to keep your and your building safe from fire damage.


We’ve included some general tests you should perform weekly and monthly to ensure your fire system is in top working conditions. This information provides general guidance of fire detection and fire alarm system users, based on the British Standards. For more detailed guidance and recommendations, consult the BS 5839 code.


We also offer professional servicing for more in-depth maintenance and inspection. These aren’t needed as frequently, but are just as important. Reach out to us to learn more!

Routine testing by the user

To maintain the safety of your premises, it’s crucial to conduct regular fire equipment maintenance. Depending on the type of product, the service interval may vary from weekly to monthly. Although certified checks are necessary, it is equally important to perform weekly self-checks to guarantee the batteries, wiring, and the overall condition of your equipment are in proper working order.

Each week test:

  • A different manual call point during working hours to cheek that the control panel and alarm sounders operate satisfactorily.
  • Voice alarm systems to ensure they are working correctly. If the system is connected to an Alarm Receiving Centre (ARC), alert them to when testing will take place.

Each Month Test:

  • Any automatically started generator used for the fire detection and fire alarm system should be tested.
  • Any vented batteries used as a standby power supply for the fire detection and fire alarm system should be inspected for corrosion or loss or power.

Inspection and test of a system over a 12 month period

  • The switch mechanism of every manual call point should be tested
  • Every automatic fire detector should be examined and functionally tested. This includes, but is not limited to; smoke detectors, resettable heat detectors, optical beam smoke detectors, aspirating fire detection systems, carbon monoxide fire detectors and flame detectors
  • All fire alarm devices (both visual and audible) should be tested
  • Certain filament lamps should be replaced
  • Radio fire detection and fire alarm system signal strengths should be checked
  • Visual inspection of readily accessible cable fixings should be undertaken
  • The cause and effect programme should be checked
  • The standby power supply capacity should be checked
  • Other annual checks and tests recommended by the system component manufacturers should be undertaken
  • Outstanding defects should be reported and the servicing certificate issued.

Quarterly inspection of vented batteries

  • Vented batteries should be examined and topped up if necessary

Non-routine attention

The arrangements in the above section, inspection and servicing are intended to maintain the system in operation under normal circumstances. However, from time to time, the fire alarm system is likely to require non-routine attention, including special maintenance.

Non-routine maintenance includes

  • special inspection of an existing fire alarm system when a new servicing organization takes over servicing the system;
  • repair of faults or damage;
  • modification to take account of extensions, alterations, changes in occupancy or false alarms;
  • action to address an unacceptable rate of false alarms;
  • inspection and test of the system following a fire.
