Legal foundation
What do the fire alarm regulations require?
Article 13 of the Fire Safety Order requires appropriate fire detectors and alarms where necessary to safeguard relevant people. What is appropriate depends on the premises, activities, hazards, dimensions, use, equipment, substances and maximum occupancy.
Government workplace guidance states that a fire detection and warning system is required. That does not mean every workplace needs identical automatic detection, sounders or monitoring. The FRA and fire strategy should establish the objective and suitable solution.
Design basis
Manual warning, automatic detection and alarm categories
In a small simple workplace, a manual method may be adequate if fire will be discovered quickly and the warning can be heard everywhere. Sleeping risk, hidden areas, lone working, vulnerable occupants, complex escape or property-protection objectives can require automatic detection or a more sophisticated system.
The category—such as L1 to L5 or P1 to P2—describes the protection objective and extent. It is not a quality grade or a shortcut for design. Record the category, variations, cause-and-effect, zoning and interfaces relied upon.
- Define life-safety, property or combined objectives
- Consider every normal and foreseeable occupancy
- Check audibility and accessibility, including people needing assistance
- Coordinate doors, lifts, smoke control, suppression and remote monitoring
- Record agreed variations and their justification
- Update documentation after extensions or modifications
Keeping it reliable
User testing and competent servicing
A user test confirms a selected part of the system operates and the signal is received as expected. It does not replace competent inspection, preventive maintenance or testing of all devices and functions.
GOV.UK requires regular checks and faults to be recorded. Recognised standards commonly support weekly user tests and competent inspection at intervals not exceeding six months for many non-domestic systems, but the exact regime should follow the current standard, system design, manufacturer information and FRA rather than being presented as a universal statutory timetable.
| Activity | Purpose |
|---|---|
| Routine panel check | Confirm normal condition and identify faults, disablements or power problems |
| User alarm test | Confirm an initiating device and warning path operate as expected |
| Competent inspection and service | Examine devices, power supplies, functions, records and maintenance needs |
| Cause-and-effect test | Verify linked systems and programmed responses where applicable |
| Post-change verification | Confirm extensions, modifications or building changes have not weakened coverage |
Evidence and faults
What records should be kept?
Keep system design and commissioning information, category, zoning, variations, user tests, services, faults, false alarms, disablements, changes and action closure. Records should show what protection was unavailable and what temporary measures were used.
Persistent unwanted alarms should be investigated, not solved by disabling detection without assessment. Serious faults may require immediate temporary warning arrangements, fire watch, restriction of use or other competent advice.
- System category, design basis and agreed variations
- Zone plan and current operating instructions
- Commissioning, acceptance and handover records
- User tests and competent service visits
- Faults, false alarms, disablements and interim controls
- Modifications and updated as-fitted information
