A fire alarm system is only as reliable as the maintenance behind it. HRB Mech provides commercial fire alarm maintenance for businesses across the UK, from planned preventative servicing and commercial fire alarm testing through to reactive callouts and 24/7 monitoring. Every visit is carried out by qualified engineers to BS 5839-1, so your system stays compliant, your documentation stays current, and your building stays protected.
Commercial fire alarm maintenance is the planned and reactive servicing of fire detection and alarm systems in non-domestic premises. It covers routine device testing, control panel inspections, fault diagnosis, component replacement, and compliance documentation.
It is also a legal requirement. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has a duty to keep all fire safety equipment in efficient working order. BS 5839-1 defines what that maintenance must involve, how often it needs to happen, and how it should be documented. HRB Mech handles all of it on your behalf.
BS 5839-1 requires commercial fire alarm systems to be professionally serviced every six months by a competent person. At each visit, our engineers test every device, inspect the control panel, check power supplies and backup batteries, update your fire log book, and issue a full service certificate on completion.
We use specialist equipment to functionally test every component on your system, including smoke detectors, heat detectors, manual call points, sounders, and beacons. Each device is verified for correct activation and response. Any device that underperforms is flagged immediately, before it becomes a compliance issue or a gap in your protection.
Commercial fire alarm monitoring connects your system to a 24-hour Alarm Receiving Centre (ARC), providing a response to any activation, whether your building is occupied or not. HRB Mech can advise on the right commercial fire alarm monitoring service for your building and integrate it with your existing system.
Panel warnings, amber fault lights, and intermittent beeping cannot be left unattended. HRB Mech provides reactive callout support with qualified engineers available to diagnose faults, replace failed components, and restore your system to full operation, with a written record of all work carried out.
Moving away from a previous contractor? We carry out a full system audit before any agreement begins, identifying outstanding faults, documentation gaps, and anything that falls short of current BS 5839-1 requirements. You get a clear, honest picture of where things stand before we start.
Weekly (user checks)The responsible person should activate a single manual call point each week, rotating through all call points over time, and record the result in the fire log book.
A full professional service by a competent engineer, covering all devices, panel diagnostics, battery testing, and compliance certification. HRB Mech schedules these in advance so nothing gets missed.
Combined with the six-monthly visit, the annual inspection ensures 100% of devices have been tested within any 12-month period. Sounder audibility, ARC monitoring connections, and system compliance are all reviewed and documented.
We check your fire log book and previous service records before starting, so any reported faults or outstanding items are picked up from the outset.
Every detector, call point, sounder, beacon, and panel is checked for damage, obstruction, dust build-up, and environmental factors that could affect performance.
Each detection device is individually tested using calibrated equipment. Smoke detectors, heat detectors, and manual call points are all verified for correct activation and response, with results recorded.
We review fault indicators, zone configurations, programming settings, the panel clock, and all peripheral connections to confirm everything is operating as designed.
Mains supply, power units, and standby batteries are tested at every visit. Batteries that are degrading are replaced before they fail.
Where your fire alarm integrates with door releases, emergency lighting, or access control, we test those connections to confirm correct operation.
All work is recorded in your fire log book. You receive a BS 5839-1 compliant service certificate on completion, plus a clear written report of any remedial works identified.
