What a fire alarm system includes
A fire alarm system is a set of interconnected components working together to detect fire and warn occupants. At the centre sits the control panel, which monitors every device on the system and triggers the warning when a fire is detected. Automatic detectors (smoke, heat or multi-sensor) watch for fire around the building. Manual call points give occupants a way to raise the alarm themselves. Sounders, bells and beacons broadcast the warning across the site. Fire-resistant cabling holds the whole thing together and keeps signals moving even as a fire develops.
Conventional or addressable?
Conventional fire alarm systems divide the building into zones. When a device on a zone activates, the panel knows the zone but not the specific device. That is fine for smaller premises where you can quickly investigate a zone in person.
Addressable fire alarm systems give every device a unique digital identity, so the panel reports the exact location of the activated device. That level of detail matters in larger, more complex buildings where "which alarm went off?" needs an instant, specific answer.
Standards and compliance
BS 5839-1 is the British Standard code of practice for fire detection and fire alarm systems in non-domestic premises. It covers design, installation, commissioning and maintenance, and defines system categories from L1 (full protection covering every part of the building) through L2, L3, L4 and L5 (life protection at various levels), P1 and P2 (property protection), to M (manual call points only).
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for non-domestic premises in England and Wales must make suitable arrangements for detecting fire and warning occupants, based on the findings of the fire risk assessment. A system installed and maintained to BS 5839-1 provides a defensible basis for meeting that duty.
Suitable building types
Fire alarm systems are typically installed in offices, factories, warehouses, retail units, care homes, schools, hospitals, and any building where the size, layout or occupancy makes a single standalone alarm inadequate. For domestic properties and small standalone premises, our standalone fire alarm range and smoke alarm range will be a better starting point.
For specifiers and installers, our range covers panels, detectors, call points, sounders and fire-rated cable from established UK manufacturers.
