System visuals

Project and product detail

Relevant visuals that help show how the system is planned and used.

Site requirement

The alarm must reflect how the premises opens, closes and operates

Staff routes, delivery doors, offices, stock, workshops, yards, pets, machinery, shift patterns and out-of-hours access all affect detection, arming areas, user control and the response plan.

  • Door and window protection
  • Internal movement detection
  • Photo verification where suitable
  • External and perimeter detection
  • Keypads, tags and user permissions
  • App control and event history
  • Professional monitoring options
  • Maintenance and takeover support
Products and system options

Commercial Ajax protection designed around the site

The same Ajax platform used for high-quality residential systems can be configured for shops, offices, hospitality, warehouses and industrial premises. Device choice, areas, permissions, signalling and external protection are planned around how the business operates.

Door and window protection

Opening detectors protect entrance doors, staff doors, stock rooms, offices and other access points that matter to the business.

Ajax touchscreen keypad with clear commercial controls

Touchscreen keypad control

Clear visual controls, areas and individual permissions make opening, closing and managing several parts of the site easier for authorised staff.

Ajax outdoor detector with photo verification

Outdoor and perimeter detection

Suitable external detectors can add earlier warning around yards, approaches, loading areas or exposed routes after environmental risks are assessed.

A professionally positioned external siren provides visible deterrence and a clear local warning as part of the wider intruder alarm design.

Project process

Survey, design, installation and ongoing support

01

Operational survey

We review access, staff use, valuable areas, external routes, current systems and the required response.

02

Detection and control design

Zones, devices, arming areas, user permissions, communication and monitoring are planned together.

03

Installation and configuration

Devices are positioned, commissioned and tested around realistic opening, closing and occupied conditions.

04

Handover and annual support

Users, keyholders, apps, event history, monitoring and maintenance are explained clearly.

What the design needs to solve

System decisions linked to the operational requirement

01

Internal protection

Doors, movement routes, offices, stock and vulnerable areas are protected around the way the premises is occupied.

02

External detection

Suitable perimeter devices can provide earlier warning around approaches, yards or exposed external areas after false-alarm risks are assessed.

03

Monitoring

Professional monitoring is different from an app notification. Suitable maintained systems can signal agreed events through a confirmed route.

04

Takeovers and upgrades

Existing wired, wireless and hybrid systems can be inspected for access, faults, parts availability and a practical maintenance plan.

Pricing factors

What affects the commercial quotation

The final price reflects the site, system, access and operational requirements confirmed during the survey.

  • Number of doors, areas and devices
  • Internal, external and perimeter detection
  • Building construction and radio coverage
  • User, partition and access requirements
  • Monitoring and communication equipment
  • Existing system and cabling
  • Several buildings or sites
  • Out-of-hours installation

Telesis industrial premises with Fire and intruder systems installed by NOX
Industrial Fire & Security · Derbyshire

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.

NOX Fire and Security van at a Dronfield industrial site protected with Ajax perimeter detection
Industrial perimeter protection · Dronfield, Derbyshire

Perimeter Alarm Protection for an Industrial Site near Dronfield

The Dronfield site contained open approaches, working areas and stored materials that could be reached before an intruder entered the main building. Internal alarm detection alone would therefore have provided warning too late in the sequence. NOX surveyed the genuine routes into the site, selected positions around the yard and covered areas, installed five Ajax outdoor detectors and an external warning siren, then tested the individual perimeter zones around the way the industrial premises operates each day.

Industrial CCTV and intruder protection installed at a commercial unit in Chesterfield
Industrial CCTV · Chesterfield, Derbyshire

Industrial CCTV and Intruder Protection in Chesterfield

This Chesterfield industrial unit required a joined-up security system that could provide useful recorded coverage around the building while also strengthening the premises with modern intruder protection. The camera design was based on the shape of the unit, the roller-door elevation, parking and vehicle movement, exposed corners and the external approaches used during normal operation. NOX combined the CCTV and alarm work into one coordinated industrial-security project, with the finished positions selected for practical evidence rather than simply adding cameras wherever access was easiest.

Banana Industries premises with the NOX van and installed external security equipment
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

Professional planning, installation and local support

★★★★★
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.

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.

Common questions

Answers before a commercial survey

Can a commercial alarm be monitored?

Suitable systems can use professional monitoring, subject to compatibility, communication, maintenance and the agreed keyholder response process.

Can an alarm protect a yard or external area?

Yes, where suitable external detection can be positioned around the site and normal movement, animals, vehicles and boundaries have been considered.

Can staff have different access permissions?

Suitable systems can use individual users, tags, app permissions and partitions so access and event history are clearer.

Can NOX take over an existing commercial alarm?

Often yes, subject to system make, access, condition, documentation, compatibility and parts availability.

Do commercial alarms need servicing?

Planned servicing helps check devices, batteries, communication, sirens, event history and system condition. Monitoring arrangements may also require an agreed maintenance route.

Can the alarm and CCTV be designed together?

Yes. The systems remain separate in function but can be surveyed and planned together around the same site priorities.
