Feedback about local servicing and 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
Clear answers before you commit
What happens when the monitored fire alarm activates?
The agreed alarm signal is received through the professional monitoring route and handled using the nominated contacts and escalation procedure confirmed for the premises.
Can any existing fire alarm be monitored?
Not automatically. The panel, signalling options, system condition, records and maintenance arrangements need to be reviewed first.
Is fire-service attendance guaranteed?
No general attendance promise is made. The exact signalling and response arrangement is confirmed in writing for the specific system and premises.
How is professional monitoring different from an app alert?
An app alert depends on the user seeing and acting on a notification. Professional monitoring provides a defined signal-handling and escalation process using the agreed contacts.
Does monitoring replace fire alarm servicing?
No. Monitoring and planned servicing have different purposes and should work together where the system and premises are suitable.
