Assessment, repair and takeover support for existing fire alarm systems
NOX can assess suitable existing fire alarm systems where the history is unclear, faults are present or the customer wants to move maintenance from another provider. Acceptance depends on system condition, access, records, compatibility and parts availability.
What the service needs to solve
A takeover starts with understanding what is installed and what can be supported safely
Panel make, programming access, device types, zone information, service history, known faults, disabled equipment, documentation and parts availability all affect the route. NOX will separate the initial assessment, required remedials and future service agreement clearly.
- ✓ Existing-system assessment
- ✓ Panel, zones and fault-history review
- ✓ Access and documentation checks
- ✓ Device and warning-circuit assessment
- ✓ Repair or replacement options
- ✓ Remedial quotation

Commercial Fire & Security · Brimington, Chesterfield
Black CCTV and fire first-fix at The Tan Station
The Tan Station was being created as a modern customer-facing premises with a strong black interior and exterior finish. Leaving fire and security planning until the end would have risked exposed routes, awkward device positions and equipment that looked disconnected from the completed fit-out. NOX became involved during the project, completed the fire-alarm first fix and installed black internal and external CCTV in positions selected around the layout, finishes and intended use of each area.

Industrial Fire and Intruder Installation for a Derbyshire Warehouse
The Telesis Hitachi premises required modern fire protection and intruder security that could be installed around an operational industrial environment. The two systems needed to be coordinated as one project without confusing their separate life-safety and security functions. NOX installed the Ajax EN54 Fire Hub, manual call points and warning devices alongside the commercial intruder equipment, then tested normal operation, manual activation, alarm indication and evacuation functions before completing the handover with the responsible users.

Commercial Fire & Security · Sheffield, South Yorkshire
Commercial Fire and Intruder Installation for Banana Industries
Banana Industries had inherited older intruder controls that no longer provided the clear, modern user experience required by the business. The premises also had separate fire-protection needs, so the project had to be coordinated without treating the fire and intruder systems as one combined function. NOX assessed the existing arrangement, replaced the ageing alarm controls with Ajax equipment, introduced new detection and opening protection, installed the external NOX siren and completed a clear handover and future-support route for the Sheffield team.

Customer feedback
Advice, workmanship and local support
“We had NOX Fire & Security install our commercial fire alarm system alongside an intruder alarm, and the whole experience was spot on from start to finish. Clean, professional installation, everything clearly explained, and the system is easy to manage through the app with instant alerts. The fire system is clear, reliable and easy for the team to manage without overcomplicating things. No pushy sales, no unnecessary contracts — just honest advice and proper workmanship. You can tell they care about doing things right. Highly recommend NOX for any business looking for fire or security systems in Chesterfield / Sheffield.”Rory StirlandCommercial Fire Alarm & Intruder Alarm
“We recently had NOX install cameras, smoke screens, and alarms at our office and the whole experience has been spot on from start to finish. From the very first phone call with Isaac, everything felt straightforward and reassuring. He took the time to explain our options, answered all our questions, and helped design a system that made sense for our building and our budget. No pushy sales tactics at all, which was refreshing. The installation was smooth, the team were professional, and even after everything was fitted, Isaac has been on hand to help with any follow-up questions. A really great service and a company I'd happily recommend.”Nathan De La RosaCommercial CCTV, Alarms & Smoke Screens
“Professional, friendly and sensible pricing. From first contact to completion the process was smooth and stress-free. The team clearly know their stuff and the system is exactly what we needed. Would have no hesitation recommending NOX to other businesses.”Jez SCommercial CCTV
Common questions
Clear information before you enquire
Can NOX take over any fire alarm system?
No company can responsibly accept every system without assessment. Condition, access, documentation, compatibility and parts availability must be reviewed first.
What if the engineer code is missing?
The available access and manufacturer route need to be checked. In some cases access can be recovered; in others a panel or system change may be required.
Are fire alarm repairs included in a service?
Testing and servicing identify defects. Parts, additional labour and remedial work are normally quoted separately unless the written agreement says otherwise.
Can you repair a system that shows intermittent faults?
NOX can investigate the reported condition, event history, circuits and devices, but the required time and parts depend on the fault and system supportability.
Can emergency lighting be reviewed at the same visit?
It can be coordinated where the quotation includes both services and the site information is available.
