Types of Alarm We Maintain & Service
We maintain all types of fire alarm system, helping to ensure your site and staff stay protected.
Conventional Fire Alarm Systems
Older zone-based systems that still protect thousands of buildings. We test every call point, check all sounders, and verify detection zones. Just because it’s older tech doesn’t mean it can’t work perfectly with proper care.
Analogue Addressable Systems
Modern systems that pinpoint exactly which device activated — but only if they’re looked after properly. We test each detector individually, make sure everything’s talking to each other, and check the panel programming.
Wireless Systems
Cable-free systems perfect for listed buildings or temporary sites. We check signal strength, test battery life, and verify all devices communicate reliably. Wireless systems need extra care to keep working properly.
Networked Fire Alarm Systems
Networked systems link multiple buildings and floors. One central panel controls everything, making these systems perfect for schools, offices, and industrial sites.
Preventative Maintenance
Stop problems before they start.
Visual Inspection
Device Testing
Detectors, call points, sounders and beacons are tested in line with standards to confirm correct activation and response.
Control Panel Checks
The fire alarm control panel is checked for faults, warnings, correct configuration and time/date accuracy.
Power & Batteries
Mains supplies, power units and standby batteries are tested to ensure continuous operation during power failure.
Fire Interface Testing
Interfaces with door releases, access control, lifts and other life-safety systems are tested for correct operation.
Log Book Review
System logs and site log books are reviewed to confirm events, tests and actions are correctly recorded.
Zone Verification
Zones are verified to ensure activations display the correct location and description on the control panel.
Cause & Effect
Cause-and-effect programming is checked to confirm the system responds correctly to fire events.
Sounder Levels
Audible alarm devices are assessed to ensure adequate coverage and audibility throughout the premises.
Manual Call Points
Break glass call points are tested and reset to confirm reliable operation.
Fault Monitoring
We check fault reporting and monitoring connections to ensure alerts are transmitted correctly where applicable.
Compliance Review
The system is checked against relevant standards, with advice provided on any remedial actions required.

Robert the engineer arrived on time. He was very polite, courteous and professional. He carried out the service checking each point doing any necessary repairs showing us on his laptop the state of each point.
He did a full test before departing.

The engineer, Jamie, fitted new equipment for us and carried out our regular service/maintenance visit as well. He was very systematic and accurate in everything he did, and was charmingly courteous to us.

FAQs
Quick answers to common questions about fire alarm system maintenance, repairs and upgrades.
How often should my fire alarm system be serviced?
British Standard BS 5839 recommends different intervals based on your system type and risk level. Most commercial systems need quarterly or six-monthly servicing. High-risk sites need monthly checks.
What does a fire alarm service include?
Complete system testing following BS 5839 guidelines. We test detectors, sounders, call points, and panels. Check batteries and power supplies, clean sensors, verify programming. Update logbooks and upload reports to an online portal for reference.
Can you service systems installed by other providers?
Yes. We take over maintenance of any fire alarm system, regardless of who installed it. We start with a thorough audit bring everything up to standard, then maintain it properly going forward. Many customers come to us after poor service elsewhere.
Why is regular fire alarm maintenance important?
Three reasons: compliance, reliability, and cost. Regular maintenance is legally required and keeps insurance valid, it prevents false alarms, and catches small issues before they become expensive failures. Proper maintenance saves money long-term.
Are there legal requirements for fire alarm maintenance?
The Regulatory Reform (Fire Safety) Order 2005 requires “appropriate maintenance” of fire detection systems. British Standard BS 5839 defines this as regular testing, servicing, and documentation.
Can you service VESDA systems?
Yes. We service any Xtralis or Honeywell VESDA model. This will include visual inspections, cleaning debris and dust from sampling holes and pipes, testing how quickly the VESDA registers smoke, and reviewing fault logs.
