Fire detection and alarm systems (United Kingdom)
A list of checks and obligations with their cadence, ready to add to your agenda.
For the responsible person and for whoever manages maintenance of the fire detection and alarm system: employers, facilities managers, managing agents of common parts. It covers the general maintenance duty in article 17 of the Fire Safety Order, the weekly rotating call point test, six-monthly professional servicing, the logbook, managing false alarms, standby batteries, and end of life for panel and detectors. The two headline intervals come from BS 5839-1, a paid standard we have not read: they are technical practice, not a numerical statutory duty. It does not cover designing the system category or connection to an alarm receiving centre.

Weekly test of a manual call point
Each week a different manual call point is operated in rotation, the sounders are checked to be audible throughout the building, and the logbook records which point was tested and what happened. The weekly interval comes from BS 5839-1, a paid standard we have not read; the deadline here is monthly because the agenda works in months, so several tests will be logged between deadlines. The test is run by the responsible person or someone they appoint, after warning occupants and any alarm receiving centre.

Manage false alarms
This is a control we set ourselves rather than a statutory duty: every quarter, count the false alarms in the period, look for the cause — kitchen steam, building dust, a badly placed detector, a fault — and decide on the action. It matters because a system that sounds often for no reason stops being believed by the people in the building, and that, rather than the fault itself, is what makes an evacuation dangerous. The analysis belongs to the responsible person, with the maintainer where the cause is technical.

Replacing the standby batteries
The batteries that keep the panel and the devices alive through a mains failure are replaced at the point the panel manufacturer specifies: there is no law and no single figure, so read the system documentation and record the installation date. The annual check suggested here exists to compare that date against the stated life and to plan the replacement before the fault announces itself. Replacement normally sits within the maintainer’s visit.

End of life of panel, detectors and batteries
What triggers this rule is the replacement of the panel, of a batch of detectors or of the battery pack. All of them are electrical and electronic equipment: they go to separate collection, never into general waste, and are passed to a registered carrier with the paperwork the waste duty of care requires. The burden sits with the business holding the waste. Before collection, ask the supplier whether the detectors installed contain sources needing a dedicated route: that check is made case by case.

Keep the system logbook
The logbook takes the weekly tests, the service visits, the faults, the real alarms and the false alarms, each with date, established cause and action taken, alongside the system design details. It is the document the responsible person shows to an inspector, and it is also the only place where a panel that keeps reporting faults becomes visible before someone quietly silences it. Keeping it falls to the responsible person or to the person they have nominated for the system.

Keep the fire alarm system in working order
The law asks the responsible person for a suitable system of maintenance and for an installation kept in an efficient state and in good repair: no numerical interval appears in the text of article 17. The yearly review suggested here is there to confirm that the maintenance contract covers every installed device, that the maintainer can be reached when something fails, and that the non-conformities from the last visit have been closed. The duty stays with the responsible person even where a contractor runs the system.

Six-monthly professional servicing
A competent person inspects and services the system at intervals BS 5839-1 puts at six months, with a five-to-seven-month tolerance window in the 2025 version of the standard: rotational detector testing, checks on the panel, the batteries, transmission paths and the alarm devices. The standard is paid-for and we have not read it: the interval is reported as industry practice while the legal duty remains article 17. The report signed by the maintainer should be kept and cross-referenced in the logbook.
