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
- ✓ Maintenance takeover route
- ✓ Emergency-lighting coordination where relevant

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
“Brilliant service from NOX. Super professional, knowledgeable, and they went out of their way to be helpful. Everything was explained clearly and in detail. The install was tidy, and the whole process was smooth from start to finish. We were thinking about getting a security system for a while and now we're so glad we went with NOX. Would 100% recommend to anyone.”Ryan HargreavesAjax Alarm System
“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
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.
