Perimeter Alarm Protection for an Industrial Site near Dronfield
Five Ajax outdoor detectors and an external warning siren creating an earlier perimeter alarm layer around a working industrial site near Dronfield.
What the property or business required
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.
Create dependable earlier warning around the exposed approaches to the working industrial site while accounting for stored timber, covered areas, vehicles and normal staff movement.
NOX installed five Ajax outdoor detectors and an external warning siren, configured the relevant perimeter zones, checked communication and detection around the selected routes, and completed a practical site handover.

How NOX approached this industrial perimeter protection project
The installed equipment matters, but the positions, property layout, operating routine and handover determine whether the finished system is genuinely useful.
Coverage and requirement
Create warning around the exposed external approaches before an intruder reaches the building, rather than relying only on internal detection after entry.
Installation planning
Position the detectors around actual routes, stored materials and working areas so the perimeter layer supports normal site activity instead of generating avoidable alarms.
Control and handover
Use a clear external warning point and complete a practical handover so the perimeter system works as one layer alongside the building security, site procedures and physical protection.
What was delivered at Dronfield, Derbyshire
The industrial site received five tested Ajax outdoor detection zones and an external NOX warning siren, creating a dedicated earlier-warning layer across the key exposed approaches, covered stock areas and working routes near Dronfield.
Industrial and yard security around Dronfield often involves open boundaries, stored stock, vehicles, covered areas and regular daily movement. External detection needs to be surveyed around the layout, vegetation, wildlife, communication range and staff routines to remain useful in practice.

Can Ajax outdoor detectors protect a commercial yard?
Yes, where the survey confirms suitable positions, communication range and detection routes. External detection should be designed as a separate layer and tested around the way the yard operates.
Does perimeter detection replace CCTV or physical security?
No. It adds earlier warning. CCTV, lighting, gates, locks, fencing, response procedures and internal detection may still be required as part of the wider site strategy.
How are false alarms reduced on an industrial perimeter system?
The survey should consider detector height, direction, vegetation, wildlife, vehicles, stored materials and normal staff movement. The final settings then need to be tested around real site conditions.
