Fire Alarm Testing
BS 5839 Certified Testing
Professional fire alarm testing and servicing by BAFE registered engineers in accordance with BS 5839-1. Compliance certificate included with every visit.
What is Fire Alarm Testing?
Fire alarm testing is a structured inspection and service of your fire detection and alarm system. We check every part of your system — detectors, call points, sounders, wiring, and the control panel. If a fire starts, your alarm needs to detect it and warn everyone in the building. Testing confirms that it will.
All fire alarm testing in the UK must follow BS 5839-1:2017, the British Standard for fire detection and alarm systems. The Regulatory Reform (Fire Safety) Order 2005 makes this a legal duty for the responsible person.
What Our Fire Alarm Testing Includes
- Control panel inspection — full functional test of zone indicators, fault conditions, and communication with all connected devices
- Detector and call point testing — every detector and manual call point individually tested for correct activation and response
- Sounder and visual alarm verification — all sounders, bells, and visual alarm devices checked across their coverage area
- Battery backup testing — standby batteries tested under load to verify they can power the system during mains failure
- Log book completion — fire alarm log book completed on-site, recording all tests and faults found
- Fault identification and reporting — any faults documented with clear recommendations and priority levels
- Certificate of compliance — confirming your system has been tested to BS 5839-1:2017

Fire Alarm Categories (BS 5839-1)
BS 5839-1 classifies fire alarm systems into categories based on their purpose:
- Category M — Manual-only systems. No automatic detection. Only suitable for very small, simple premises.
- Category L (Life Protection) — L1 (full building detection), L2 (defined high-risk areas), L3 (escape routes only), L4 (escape routes in dwellings), L5 (specific locations per fire risk assessment).
- Category P (Property Protection) — P1 (full building detection), P2 (defined high-risk areas).
Most commercial buildings need at least a Category L2 or L3 system. HMOs and care homes typically require L1.
System Types
- Conventional — Zone-based systems dividing a building into numbered areas. Common in smaller buildings.
- Addressable — Each device has a unique digital address for precise identification. Standard for larger buildings.
- Wireless — Radio frequency systems for listed buildings and premises where cabling is impractical.
