About this service
A fire alarm system detects and warns occupants of fire using manual call points, automatic detectors, sounders, control equipment and sometimes interfaces to doors or other systems. The design must follow the building’s fire-risk assessment, occupancy and evacuation strategy.
Installing more detectors without a design does not automatically improve safety. Detector category, zoning, sound levels, false-alarm management, standby power and maintenance access all need consideration.
Common problems we help with
System no longer matches the building
Partitions, use and occupancy may change without zones or detector coverage being updated.
Persistent false alarms
Contamination, wrong detector type, poor siting or unmanaged building activities can create repeated unwanted signals.
Faults or disabled zones
Battery, wiring and device faults can reduce coverage if left unresolved.
No reliable records
Missing logbooks, drawings and service history make faults and compliance harder to manage.
How we carry out the work
Confirm the design basis
We review the fire-risk assessment, required category, evacuation arrangement and interfaces.
Install or alter the system
Devices, circuits, zones and controls are fitted to the agreed design with disruption coordinated.
Commission and hand over
Cause-and-effect, sounders, detection, standby supplies and controls are tested, then records are supplied.
What is normally included?
- Initial discussion about the property, symptoms, priorities and timescale
- Assessment of the relevant circuit, equipment, access and existing protection
- A written scope for the proposed fire alarm systems work
- The agreed installation or repair work, with disruption kept to a reasonable minimum
- Inspection, electrical testing and appropriate handover documentation
Before the work starts
- The building layout, escape routes and areas that genuinely need coverage
- Who uses the system and how alerts, entry or routine tests will be managed
- Cable routes, power supplies, networking and resilience during an outage
- Ongoing testing, maintenance and record-keeping requirements
What affects the price?
The price depends on the existing installation and the amount of work required. For fire alarm systems, the main factors normally include:
- Device and detection-point quantity
- Wired, wireless or hybrid infrastructure
- Access at height and containment requirements
- Monitoring, recording, integration and maintenance options
Testing, certificates and handover
Once the installation work is complete, we inspect and test it and provide the records that apply to the job.
- System demonstration for the people who will use it
- Device, zone or camera schedule as appropriate
- Test results and commissioning information
- Maintenance and routine-user-check guidance
Fire Alarm Systems questions
Can you design the system from a floor plan?
Plans help, but occupancy, fire strategy, compartmentation and site conditions must also be understood.
How often does a fire alarm need servicing?
The maintenance interval should follow the applicable system standard and fire-risk arrangements, with regular user tests between visits.
Can existing detectors be reused?
Only if they are compatible, in suitable condition, correctly positioned and within their service life.
Booking the work
What happens after you contact us
1. Discuss the job
Tell us about the property, the symptoms or the result you want. Photographs and model numbers are often helpful.
2. Inspect and quote
We check the relevant installation and give you a written quotation showing what is included.
3. Complete and test
We carry out the agreed work, verify it electrically and explain any controls, labels or certificates at handover.
