Know When Workers Enter Your Equipment's Blind Spot
The SCAN~LINK Single Node Detection System uses passive RFID to alert operators when a tagged ground worker enters the danger zone behind or around mobile equipment. One antenna, one in-cab display, and one external alarm work together to give both the operator and the worker on the ground a clear warning, while every detection event is recorded for review.
Add a Dedicated Layer of Detection Around Your Heavy Equipment
Reversing machines and limited sightlines put ground workers at risk every shift. The Single Node Detection System adds detection where operators need it most, so they get an alert when a tagged worker is close and extra caution is required.

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.
Passive RFID Detection
The antenna continuously scans for passive RFID tags in SCAN~LINK vests, hard hats, and marker tags. No batteries on workers means nothing to charge, swap, or forget.
Dual-Sided Alerts
The in-cab display warns the operator with bright LEDs and an audible alarm. At the same time, the external alarm sounds outside the machine to warn the worker on the ground.
Automatic Event Logging
Every detection is recorded with the time, date, and apparel ID. That gives your safety team objective near-miss data to support training, reporting, and compliance.
Adjustable Detection Range
The beam-shaping antenna covers a typical range of around 20ft/6m. Detection range can be adjusted to match your machine and the way it operates on your site.
Single Node Components & Specifications

Antenna Unit
Housed in a rugged, sealed, weatherproof enclosure, the beam-shaping antenna monitors the area behind the equipment. It relays detections wirelessly to the in-cab display and stores event data for later retrieval.
Specifications
Input Voltage: +12VDC – +28VDC
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

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™ Single Node Detection System.
Do workers need to charge or maintain their tags?
No. SCAN~LINK uses passive RFID tags, which have no batteries and don't require any charging or maintenance. Workers just have to wear their Armour-equipped vest and/or hard hat like standard PPE.
Will the system detect workers from other crews or sites?
Yes, as long as they are wearing SCAN~LINK RFID-tagged PPE. Any equipment fitted with a SCAN~LINK Armour Antenna can detect any worker wearing Armour-equipped apparel, regardless of crew, contractor, or site.
When should I choose the Dual Node system instead?
The Single Node Detection System suits equipment where one detection zone covers the main blind spot. If your machine needs extended coverage from more than one antenna, the Dual Node system offers a cost-saving way to add that coverage with a single in-cab display.
Can detection data be sent to SCAN~VUE?
Learn More About SCAN~VUEYes. With a Telematics Interface Unit (TIU), detection events are transmitted to the SCAN~VUE™ platform, where you can view heat maps, run reports, and track trends from any device.
