BS 5839-1

Fire Alarm Testing & Servicing

Periodic inspection and servicing of commercial fire detection and alarm systems by a competent person, to BS 5839-1, with weekly-test guidance for your own team.

What periodic servicing covers

BS 5839-1 sets out a routine of testing for commercial fire detection and alarm systems that sits alongside — not instead of — the weekly test your own staff carry out. A competent person visits to test detectors, call points, sounders and the control panel, check standby battery condition, and confirm the system still matches the current layout and use of the building.

Price depends on zone count and panel type — confirmed before booking.

What we check

  • Control and indicating panel condition and event log
  • Standby battery condition and charging circuit
  • A sample or full round of detectors and call points, tested on rotation
  • Sounders, beacons and any voice alarm equipment
  • Interfaces to door releases, lifts, plant shutdown and AOVs where fitted
  • Zone plan accuracy against the current building layout

Weekly testing — still your responsibility

Between our visits, BS 5839-1 expects a weekly test of one call point by a nominated person on site, logged in the fire logbook. We check this log at every visit and can talk your team through it if the system is new.

Who this is for

Offices, retail units, HMOs and blocks of flats with communal detection, warehouses, and any commercial premises where a fire risk assessment specifies an addressable or conventional detection system.

Frequently asked questions

How often does a fire alarm need professional servicing?

BS 5839-1 recommends a visit at least every six months for most commercial systems, with the interval and scope confirmed by your fire risk assessment and system design.

What's the difference between the weekly test and your service visit?

The weekly test — a single call point, done by someone on site — checks the alarm still sounds. Our visit is a fuller inspection: batteries, a rotating sample of detectors, panel diagnostics and confirming the zone plan still matches the building.

Do you issue a certificate?

Yes — a servicing certificate confirming what was tested, any faults found, and recommended remedial action, matched against the fire logbook.
