Fire Alarm Servicing: What Checks Are Done?

Regular servicing keeps a fire alarm system reliable and helps meet the requirements of BS 5839. Here is what typically happens at each stage.

Weekly user test

The responsible person on site should test the system every week by operating a different manual call point and checking that the alarm sounds and the panel shows the correct zone. This confirms the system is working between engineer visits.

Six-monthly service

A competent engineer carries out a more thorough inspection. Typical checks include:

• Testing a proportion of detectors, call points and sounders
• Checking the control panel for faults and battery condition
• Verifying that the system still matches the building layout
• Inspecting cabling and devices for damage or obstruction
• Confirming that the log book is up to date

Any faults found are recorded and rectified or reported for further work.

Annual inspection

Once a year the engineer aims to test all devices over the course of the service programme. This includes:

• Full functional test of detectors and call points
• Battery capacity check and replacement if needed
• Verification of cause-and-effect programming (for example, which sounders activate)
• Review of the system against current building use
• Issue of a service certificate

Why it matters

A serviced system is more likely to work when needed, reduces false alarms, and provides evidence for insurers, fire risk assessments and enforcing authorities. BAFE registered companies follow recognised schemes for maintenance, which gives building owners extra assurance.

Maintenance contracts

Most commercial buildings use a maintenance contract so that visits are planned, certificates are issued on time, and out-of-hours support is available if the system develops a fault. View our fire alarm maintenance service or request a quote.
