[Request an Estimate](/contact-us) [07360 538643](tel:07360538643) Trusted by landlords, developers & letting agents across South Wales. 15+ Years on the tools BS 5839 Certified to standard 24–48h Typical callout window 100% Insured & DBS-checked Service overview ## Fire Alarm Maintenance, explained without the jargon ### What it is Repair, fault-finding, battery replacement, device replacement, panel reprogramming and planned preventative maintenance for fire alarm systems of any age or manufacturer. ### Who it's for Owners and managers of buildings with a fire alarm fault, a fault-light that won't clear, a system out of warranty, or a system inherited from another contractor. ### When it's needed Whenever the panel shows fault, fire, disablement or pre-alarm; after a power surge or water ingress; when batteries reach end-of-life; or as part of a planned refresh. ### Why professional matters An alarm in fault is not protecting anyone. Every hour the system is degraded is an hour of unmanaged risk and unfiled insurance paperwork. The cost of ignoring it ## What an unmaintained system actually does ### Risks if left unchecked - ● Silent detection failure, head still in the ceiling, electronics dead inside. - ● Battery sulphation that leaves the panel unable to ride out a 30-minute mains failure. - ● False activations that empty buildings, attract fire-and-rescue charges and erode trust. - ● Disabled zones quietly left off after a previous fault, entire floors unprotected. ### Common mistakes - ● Pressing 'silence' until the next service rather than logging the fault. - ● Replacing one detector with a non-compatible brand and breaking loop integrity. - ● Leaving an isolated zone isolated 'just until the contractor comes back'. - ● Assuming the alarm is fine because the green light is on. Maintenance is cheap. Replacing a system that has been allowed to corrode for five years is not. Most callouts we attend would have been a simple battery replacement on a planned visit. Our process ## A clear path from enquiry to certificate 1. Step 1 ### Call & triage You reach a real engineer, not a call centre. We triage the fault over the phone and tell you what is safe to do in the next 30 minutes. 2. Step 2 ### Attendance Same-day for contract clients, 24–48 hours otherwise. Van stocked with batteries, detectors and panels for the systems we cover most. 3. Step 3 ### Diagnosis Loop voltage, current draw, panel event log and device-by-device walk through. We tell you what failed and why. 4. Step 4 ### Repair or quote Minor work completed on the visit at our published hourly rate. Anything larger quoted in writing before we leave. 5. Step 5 ### Update certificate Maintenance record added to your log and emailed, your servicing chain stays intact. Why clients stay with us ## Specific, measurable benefits ### One contractor Install, service and maintenance under one accountable team, no finger-pointing. ### Real response times Published SLAs, not 'we'll get to you eventually'. ### Stock on the van Most contract jobs fixed first visit because the parts are already on board. ### Fixed pricing Hourly and per-device rates published up front. No after-hours mark-up shocks. ### Audit trail Every visit added to your digital log, useful when an inspector arrives. ### Brand-agnostic We maintain Hochiki, Apollo, Kentec, Advanced, Aico, Honeywell, Menvier and Texecom. Technical detail ## Everything that goes into a proper fire alarm maintenance Maintenance is where most fire alarm systems quietly fail. The work below is the bread and butter of what our engineers do across South Wales every week. ### Battery replacement Panel standby batteries should be load-tested annually and typically replaced at 4 years. Sealed lead-acid cells lose capacity silently; the panel still shows green right up to failure. We carry every common size on the van. ### Detector replacement Optical and multi-sensor detectors have a 10-year service life. Beyond that, sensitivity drift causes both missed detection and false alarms. We document the install date of every head we fit so end-of-life is never a surprise. ### Panel and loop fault-finding We diagnose addressable loops by current draw and event-log analysis, not by 'replace and see'. Conventional zones are traced with a meter and a plan, not by ripping out cable. ### Cause-and-effect reprogramming When a building's use changes, new partition walls, repurposed rooms, additional flats, the panel's cause-and-effect needs updating so the right zones sound on the right detection. We make those changes in writing. ### Water, dust and contamination Refurbishments, leaks and kitchen vapours kill detectors. We replace heads as needed and document the cause so insurance and landlord claims can be evidenced. ### End-of-life decisions When a system is uneconomic to maintain we say so, and quote a like-for-like replacement against a year of repair forecasts so the numbers are clear. Frequently asked ## Frequently asked questions How quickly can you attend a fire alarm fault? Contract clients: same-day across South Wales. Non-contract: typically 24–48 hours, sooner where possible. Do you charge a callout fee? Can you maintain a system you didn't install? Do you offer out-of-hours cover? What if a part is no longer manufactured? How do I know whether to repair or replace? Will my insurance cover a third-party maintainer? Do you cover Bristol as well as South Wales?
