Commercial fire and integrated system work
Genuine project photography and confirmed scopes showing fire, intruder and wider site requirements.

Black CCTV and fire first-fix at The Tan Station
The Tan Station was developed around a modern, premium interior and exterior finish. NOX coordinated black CCTV equipment with the property design and completed fire-alarm first-fix work during the fit-out stage, helping the different systems sit naturally within the wider project.

Industrial Fire and Intruder Installation for a Derbyshire Warehouse
The Telesis Hitachi premises required a modern Fire and intruder solution suited to an operational industrial environment. NOX installed the system around the building, configured the Ajax EN54 Fire Hub, tested manual activation and evacuation functions, and completed the system handover.

Commercial Fire and Intruder Installation for Banana Industries
NOX delivered a coordinated intruder and fire project for Banana Industries, keeping the installation and handover within one local team.
Clear installation, handover 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
