Fire Alarm Maintenance & Security System Servicing
Planned maintenance for commercial fire alarm, CCTV, intruder alarm and access control systems. We can agree one contract for several disciplines, or focus the visit plan on a specific system.
A stronger maintenance page starts with the assets on site
Maintenance is not just a reminder in a diary. It is the planned inspection, testing and record trail that keeps fire and security systems usable for the people who rely on them.
Multi-system maintenance gives facilities teams one clear plan for planned visits, fault notes, records and follow-up work across the systems protecting the site.

Fire alarm servicing
Planned fire alarm servicing, testing support, fault notes and records for existing commercial fire alarm systems. Use this route when the site needs fire-specific servicing, remedial advice or a clearer logbook trail.

CCTV maintenance
Camera, recorder, storage, retention and image quality checks for commercial CCTV systems. This route keeps footage usable, retrieval practical and site teams clear on faults or remedial work.

Intruder alarm servicing
Servicing for intruder and burglar alarm systems, including detectors, control equipment and records. Use this route when alarm reliability, signalling, response records or fault history need a dedicated service plan.

Access control maintenance
Maintenance for readers, controllers, locks, door entry equipment and credential housekeeping. This route keeps doors secure, release behaviour tested and access records practical for the people managing the site.

How a maintenance contract is shaped
Asset list
We identify the systems, panels, cameras, doors and controls that need to sit inside the maintenance scope.
Condition check
Existing systems are reviewed before cover starts, so unsupported parts, defects and exclusions are not hidden.
Visit pattern
The planned visit pattern, reporting route and callout path are agreed around the premises and the systems covered.
Records and review
Service notes, remedial items and contract changes stay visible so the maintenance plan can keep pace with the site.
One maintenance plan can cover fire alarms, CCTV, intruder alarms and access control. Visit patterns, records and callout routes are agreed for each system before cover starts.
Contract types for different estates
The right maintenance plan depends on how many systems, doors, cameras and premises need attention. Scope, pricing and exclusions are confirmed in writing before cover starts.

Maintenance should leave the next action obvious
A good service visit does more than tick off a checklist. It tells the site team what was checked, what changed and what needs attention next.
Known scope
The contract names the systems covered, so maintenance responsibilities are clear.
Service notes
Visit records make faults, remedial items and recommendations visible.
Accreditation trail
Procurement teams can use the accreditations page to review current scheme details.
Frequently asked questions
How often should a commercial fire alarm be maintained?
Commercial fire alarm maintenance is commonly planned at least twice a year, with user checks between engineer visits. The final schedule should be confirmed against BS 5839-1, your fire risk assessment, insurer requirements and competent advice.
What is the difference between testing and maintenance?
Testing checks that the system operates as expected. Maintenance is the planned service work, fault review and documentation that keeps the system in working order. Weekly user checks and engineer maintenance should both be documented.
Do you maintain systems you did not install?
Yes, subject to survey. Centurion can review the existing system, identify obvious documentation or condition issues, advise on remedial work and agree whether it can be brought onto a maintenance contract.
Can one contract cover fire, intruder, CCTV and access control?
Yes, where the systems and site access arrangements allow it. A multi-system contract can cover several disciplines under one schedule and one contract route, with discipline-specific detail handled through the relevant maintenance page.
Do maintenance contracts include emergency callout?
Callout options can be agreed as part of the contract scope. Response targets should be confirmed in writing before any contract is issued.
How often should CCTV and access control be serviced?
The right interval depends on site risk, usage, environment and system condition. Many sites plan annual checks, while higher-use or higher-risk areas may need more frequent review. The schedule should be agreed after survey.
