As a building owner, facility manager, or landlord, preparing for a fire alarm system maintenance can sometimes feel daunting. Understanding what maintenance engineers assess during these visits can help you stay compliant, protect occupants, and ensure your fire safety systems remain fully operational.
Understanding the assessment process and knowing what maintenance engineers evaluate can help you prepare effectively, protect building occupants, and maintain compliance with your legal responsibilities.
In this blog, we'll walk through what happens during a fire alarm system assessment and the key areas maintenance engineers focus on.
The Paperwork
Before any physical checks begin, a maintenance engineer will review your fire safety documentation. Keeping accurate records is a legal requirement under the UK Regulatory Reform (Fire Safety) Order 2005 and demonstrates that your fire alarm system is being properly maintained.
Key documents include:
Fire Alarm Logbook: Records of weekly manual call point tests, routine checks, faults, and corrective actions.
Service Certificates: Evidence of your scheduled maintenance visits, typically carried out every six or twelve months depending on system requirements.
Fire Risk Assessment (FRA): A current assessment identifying fire hazards
within the building and the measures in place to manage them.
The Fire Alarm Control Panel (FACP)
The fire alarm control panel is the heart of the system, and maintenance engineers will assess it carefully.
Areas commonly checked include:
Fault and Warning Indicators: The panel should display a normal operating status. Any fault lights, warning indicators, or silenced buzzers may indicate unresolved issues that require attention.
Battery Back-Up Supply: Backup batteries must be fully operational to ensure the system remains functional during a mains power failure. Engineers will check battery age, condition, and test readings.
Power Supply Identification: Circuit breakers and isolators supplying the fire alarm system should be clearly labelled to prevent accidental shutdown.
General Panel Condition: The control panel should be clean, accessible, and free from signs of damage or tampering.

Initiating Devices (Detectors and Call Points)
Maintenance engineers must verify that the system can detect a fire and initiate an alarm without delay.
Checks typically include:
Accessible Manual Call Points: Break-glass call points must be clearly visible, unobstructed, and installed at the correct height.
Detector Condition: Smoke and heat detectors are checked for dust build-up, paint contamination, damage, or anything that could affect performance.
Detector Coverage: Engineers will assess whether changes to the building layout, such as new partition walls or room alterations, have impacted detector coverage.
Alarm Notification Devices
When a fire alarm activates, occupants must be alerted quickly and effectively throughout the building.
Maintenance engineers will assess:
Audibility: Alarm sounders must be audible above normal background noise in all occupied areas.
Visual Warning Devices: Where visual alarms are required, engineers will
check that beacons and strobes are clean, operational, and clearly visible.
System Interfaces and Safety Functions
Modern fire alarm systems often interact with other building systems to support a safe evacuation.
Maintenance engineers will test functions such as:
Magnetic Door Releases: Fire doors held open by magnetic retainers should automatically close when the alarm activates.
Access Control Systems: Security doors, gates, and turnstiles should release into a safe state to allow occupants to exit quickly.
Other Connected Systems: Depending on the building, engineers may also assess smoke-control systems, lift interfaces, and other fire-safety
integrations.
Stay Prepared with Routine Maintenance
The best way to approach any fire alarm system is with consistent maintenance and record-keeping throughout the year.
