Extended Passive RFID Coverage for Equipment with Multiple Detection Zones
The SCAN~LINK Dual Node Detection System pairs two passive RFID antennas with a single in-cab display, providing extended detection coverage across multiple zones without the cost of two complete systems. When a tagged ground worker enters the danger zone, the operator receives an immediate visual and audible alert while an external alarm warns the worker on the ground.
Why Choose a Dual Node System?
Some applications require more coverage than a single antenna can provide on its own. Whether equipment has multiple blind spots, operates across a wider area, or requires detection on more than one side, the Dual Node Detection System is a cost-saving way to extend coverage where a single antenna is not enough.
A master antenna and an auxiliary antenna work together and report to one in-cab display, so operators get a single, clear alert source instead of managing multiple screens. Each system ships pre-paired, which means your team can install and test it without extra configuration.
Any machine fitted with a SCAN~LINK Armour Antenna can detect any worker wearing Armour-equipped apparel. Tags don't need batteries or charging, so workers simply wear their PPE as usual.
Extended Coverage
Two antennas create a wider detection zone around your equipment, each with a typical range of 20 feet / 6 metres. This is a practical fit for any equipment that benefits from extended coverage or requires detection across more than one zone.
User-Configurable with RapidPair™
Adjust operating parameters to suit your machine and site using RapidPair™ software and a USB dongle. Fine-tune the system without specialized equipment.
Create Multiple Detection Zones
Use two antennas to cover separate high-risk areas on the same machine. This helps tailor detection coverage to equipment layouts where one antenna alone may not provide the right zone placement.
Rugged, Weatherproof Build
The ABS/aluminum casing stands up to dust, moisture, vibration, and the daily demands of industrial worksites.
Dual Node Components & Specifications
Master Antenna Unit
The Master Antenna Unit allows both antennas to communicate wirelessly with a single In-Cab Display. It is designed to detect SCAN~LINK Safety PPE with passive RFID tags.
Specifications

IP Rating: IP56
Auxiliary Antenna Unit
The Auxiliary Antenna connects to the Master Antenna by RF cable to extend the detection zone. It is designed to detect SCAN~LINK Safety Apparel with passive RFID tags.
Specifications
Typical Range: 20 feet / 6 meters
Temperature Range: -20°C – +85°C / -4°F – +185°F
Frequencies Available: 902.3 – 927.7MHz, 920 – 926MHz, 865.7 – 867.5MHz
IP Rating: IP56
Display Unit
The compact, durable Display Unit alerts the operator with bright LEDs and an adjustable audible alarm when Armour apparel is detected. Self-diagnostic checks confirm the link to the antenna is present and the system is running normally.
Specifications
Temperature Range: -20°C – +85°C / -4°F – +185°F
Volume Controls: Pushbutton Select
Power Consumption: 1W
RF Cable
The RF Cable connects the Master Antenna to the Auxiliary Antenna. Both antennas must be connected for the Dual Node system to function properly.
Specifications
Length: 10 feet / 3 metres
Connector: Coaxial Type N
External Alarm
Mounted on the outside of the equipment, the External Alarm sounds a staccato warning so workers nearby know they are in the danger zone.
Specifications
Operating Voltage: +6VDC – +28VDC
Temperature Range: -20°C – +65°C / -4°F – + 149°F
Sound Pressure: 95±5db(S) at 6VDC at 25°C / 77°F, 109±5dB(A) at 28VDC at 25°C / 77°F
Mounting Bracket
The adjustable antenna bracket includes mounting holes on either side for securing the External Alarm, keeping installation clean and simple.
Specifications
Maximum Angle: 90º
Finish: Heavy Duty Powder Coating
FAQs
Find answers to common questions about the SCAN~LINK Armour System™ Dual Node Detection System.
How do I know if I need a Dual Node system instead of a Single Node system?
The Single Node system suits equipment where one detection zone covers the main blind spot. If your application requires extended coverage or detection across more than one zone — whether due to machine size, operating configuration, or multiple high-risk areas — the Dual Node system adds that second antenna while keeping a single in-cab display.
Does the Dual Node Detection System require complex setup?
No. Each Dual Node antenna and display set comes pre-paired, so the system can be installed and tested without extra configuration. Wireless communication between the master antenna and display reduces cabling, and low power consumption means no dedicated supply circuit is needed. If you want to adjust operating parameters, you can do so with RapidPair™ software and a USB dongle.
What is the detection range of each Antenna?
The Master Antenna and Auxiliary Antenna each have a typical range of 20 feet / 6 metres. Together, they create a wider detection zone around your equipment. Our team can help you plan Antenna placement based on your machine and site conditions.
Can the Dual Node system detect workers wearing Armour-equipped apparel from another crew or site?
Yes. Any equipment fitted with an Armour antenna can detect any worker wearing Armour-equipped apparel, regardless of crew, contractor, or site. Dual Node and Single Node systems detect the same passive RFID vests, hard hats, and marker tags.
