Fire Alarm Installation in High Wycombe: Commercial Systems to BS 5839-1

False alarms are the local pressure point

Buckinghamshire Fire and Rescue Service says it targets premises with many false alarms.

The service's business safety team runs a risk-based inspection programme. Its own page lists premises with a high number of false fire alarms among its targets, along with high-risk premises and those with fire safety concerns.

That changes what a good installation looks like. A system that goes off every fortnight draws attention and wastes occupants' time. Most false alarms come from detector choice and siting, not from faulty panels. A kitchen smoke detector, a heat source below an optical head, or dust in a workshop will do it every time.

When we design a system we pick detector types for the room, not one type for the building. If you already have a system that keeps going off, see why a fire alarm keeps going off and false alarm charges.

Which category does the building need?

The category decides the coverage. It comes from the fire risk assessment, not from us guessing.

Our category guide explains each one, and what BS 5839 is gives the background. The standard we design to is BS 5839-1:2017.

Systems by building type

Different High Wycombe premises need different answers.

Offices and converted period buildings. Thick old walls and many small rooms make wireless a sensible choice in some, and wired right in others. See wired versus wireless and fire alarms for a small office.

Shops and restaurants. Kitchens need the right detector type, and a shop may share its escape route with a flat above. See fire alarms for kitchens.

Industrial and warehouse units. High ceilings and dust. Beam or aspirating detection can suit. See warehouse fire alarms.

Communal areas of flat blocks. A communal system protects the stair and corridors, and sits alongside the fire doors. See do flats need fire alarms in communal areas.

What the install includes

Design, install, commission, hand over.

1. 1Design. We work from the category in your risk assessment, floor plans and a site visit, then issue a design with detector positions and zones.
2. 2Install. Fire-resisting cable where the design needs it, call points at exits, sounders to reach every room, and a panel in a sensible spot.
3. 3Fire stopping. Every hole we cut through a fire wall is sealed. See fire stopping in High Wycombe.
4. 4Commission and test. Every device is tested. Cause and effect is checked against the design.
5. 5Handover. You get a logbook, zone plan and a training run-through for whoever tests weekly.

Testing continues after install. See how often a fire alarm should be tested and maintenance contract cost.

Alarms alongside doors and the risk assessment

An alarm does not protect people if the doors and compartment walls fail.

An alarm tells people to leave. Fire doors and fire stopping give them time to. These are separate checks. A fire risk assessment is separate from a fire door inspection, and neither replaces the other.

If you want the assessment first, see our Buckinghamshire fire risk assessments. The national page for fire alarms covers the service in full.
