Understanding Fire Alarm Systems

Fire alarm systems detect smoke, heat or flames and alert you to act fast. There are several types: conventional, addressable, wireless. Your choice depends on the size and complexity of your property.

UK law requires suitable detection and warning systems in nearly all premises. BS 5839 is the standard that guides proper installation and testing.

Fire Alarm Installation Process

Site Evaluation

We carry out a full site survey. We identify risk areas, building layout, escape routes and occupancy types.

System Design

We design to BS 5839 Part 1 (commercial) or Part 6 (residential). Systems are categorised by purpose: L (life protection) or P (property protection).

Installation

Once approved, we install detectors, sounders, panels and call points. All equipment complies with EN 54 standards.

Handover

After setup, we commission and test every element. You get documentation and training for daily checks.

Servicing & Maintenance

Regular Testing

Weekly tests ensure that call points and alarms work. You or your staff carry these out and record in your fire logbook.

Scheduled Servicing

Twice a year, our engineers inspect your fire alarm systems. We clean detectors, test batteries and confirm zone functions.

Fault Repairs

We resolve system faults quickly. Response time matters, and unresolved issues risk compliance failures.

Documentation

Servicing must be recorded. Without a log, insurers or regulators may raise issues during audits or investigations.

Legal Compliance

Failing to install and maintain fire alarms can result in prosecution. The Regulatory Reform (Fire Safety) Order 2005 places legal duties on you as the responsible person.

More on your responsibilities can be found at UK Government Fire Safety Advice.

Frequent false alarms reduce trust in the system. We help you prevent this through correct detector placement, regular cleaning and appropriate system selection.
