What makes this hard
Hazardous areas with routine traffic
Tank farms, manifold areas and process zones are entered constantly by operators, inspectors, contractors and maintenance crews. A boundary that alarms on every entry is useless; one that alarms on none is pointless.
Unmanned areas that still matter
Remote tank farms and valve stations are visited periodically. Between visits, an unauthorised entry or a lone-working incident is entirely undetected.
Toxic zones where overstay is the danger
In areas where the hazard is exposure rather than mechanical injury, the risk is duration of stay rather than entry itself, which requires monitoring over time rather than at a gate.
Guarding by person is expensive and incomplete
A guard at a boundary covers one approach for one shift. Most sites have several approaches and most budgets have one guard.
What we deploy
On a petrochemical site, the areas that need protecting are also the areas people have legitimate reasons to enter — which is why the boundary has to know who is allowed through it.
- EF1000 radar fence units at zone boundaries and approaches, battery powered with no wiring
- Bluetooth authorised-tag whitelist matched to permit-to-work and entry authorisation
- 360° detection to 6 m with adjustable range for small exclusion zones or wider approaches
- Attendant-absence and worker-overtime alerting for lone working and long-duration tasks
- Optional vital-sign monitoring with a wristband for entrants in toxic zones
- Explosion-proof certified models for classified areas — confirm zone rating at enquiry
What changes on site
Authorised entry stops being an alarm
Because access is verified by tag, legitimate traffic passes silently and the alarm retains its meaning. A boundary that alarms constantly is a boundary that is switched off.
Unmanned periods are still protected
The fence operates continuously and reports remotely, which extends supervision to the hours when nobody is on site.
Duration is monitored, not just entry
Where the hazard is exposure, the alert that matters is the overstay alert rather than the intrusion alert, and both are supported.
A cheaper boundary than a person
One unit covers a full 360° to 6 m from a magnetic base on battery power, which makes protecting several approaches affordable rather than a staffing question.
Frequently asked questions
Can it be used in a classified area?
Explosion-proof certified configurations are available, and the standard unit is IP65 for outdoor use. Tell us the zone classification and we will confirm the suitable model before you order.
How does it handle constant legitimate traffic?
Access is verified by Bluetooth tag against an authorised list. Personnel who are permitted to be in the area pass without alarming; anyone without a tag at the boundary triggers the alarm. This is what keeps the alarm meaningful in a busy zone.
What about long-duration exposure hazards?
Working-hours statistics and overtime alerting are supported, along with attendant-absence alerts and optional heart rate and blood oxygen monitoring for entrants in toxic zones, so duration of exposure is managed as well as entry.
Does it need a network to protect the area?
No. Detection and local alarm run on the device. The network carries the remote notification and configuration.
How is it deployed across a site with several zones?
Each zone boundary gets the units it needs, and all report to the same platform, so the safety function sees one site picture regardless of how many discrete areas are protected.
