Housed in a rugged and sealed weatherproof enclosure the Sensor Unit uses its integrated beam-shaping antenna to monitor the area behind the vehicle. The sensor unit is designed to detect authentic next-generation SCAN~LINK Safety Apparel and uses a reliable wireless link to relay its information to a display unit located near the equipment operator.
OPERATING VOLTAGE: 12VDC – 28VDC nominal POWER CONSUMPTION: 7.5W-36W POWER SOURCE: Ignition and reverse signal TEMPERATURE RANGE: -20°C to +85°C RFID FREQUENCY: 902.3MHz – 927.7MHz WIRELESS LINK: 2.4GHz TYPICAL RANGE: 5 meters RoHS COMPLIANT: Yes
The durable and compact Display Unit uses both a bright visual display (LEDs) and an audible alarm (adjustable volume) to alert the equipment operator when Armour safety apparel is detected. The visual display always remains active while the audible alarm is enabled only when the equipment is in reverse. The Display Unit is linked wirelessly to the sensor/antenna unit and regular self-diagnostic checks ensure that the link to the sensor is present and the system is functioning normally.

RFID Tagged Vest
Each Armour Safety Vest features a five-way, tear-away Velcro™ design with 14 strategically positioned RFID tags for reliable detection. These highly visible vests are a bright fluorescent yellow-green color and highlighted with reflective 3M Scotchlight™ markings. Other colors, sizes and configurations are also available. Made from a durable 100% polyester material the vests are comfortable, lightweight and meet both CSA Z96-02 Class 2 Level 2 and ANSI/ISEA 107–2004a standards.
RFID Tagged Hard Hat
Combine the vest with the Hard Hat Armour kit which provides another 10 RFID tags to further enhance detection of the wearer.
SCAN~LINK Technologies manufactures, sells and provides installation services for the SCAN~LINK Armour system.
The SCAN~LINK Armour System has been designed to reduce the probability of an industrial accident by increasing the probability that personnel
working in close proximity to industrial equipment will be detected. The SCAN~LINK Armour System scans for Radio Frequency Identification (RFID)
tags using an Ultra High Frequency (UHF) transceiver operating in the unlicensed 902MHz to 928MHz Industrial Scientific and Medical (ISM) frequency
band. Proper operation of the SCAN~LINK Armour System requires that the work site is free of interference-causing Radio Frequency (RF) devices.
Such interference-causing devices may include 2-way radios, wireless crane controllers and other RFID based scanning systems operating within or near
the 902MHz to 928MHz ISM frequency band. SCAN~LINK Technologies Inc. recommends that all potential customers perform a Wireless Site Survey to
ensure that the work site is free of interference-causing Radio Frequency (RF) devices before purchasing the SCAN~LINK Armour System.
The SCAN~LINK Armour system consists of the following components:
The SCAN~LINK Armour technology consists of a UHF Antenna Array comprised of individual SCAN~LINK Sensor units mounted at strategic locations around the periphery of the vehicle. A trigger wire is available on each Sensor unit that can be used to activate an aftermarket back-up alarm on detection of SCAN~LINK Safety Apparel. The SCAN~LINK Armour system is designed on a platform that is expandable. Single-sensor applications such as front-end loaders are supported, as well as custom applications that require multiple sensors for optimum circular coverage. The range of the detection can be adjusted to suit the needs of the application anywhere from 2 meters to 5 meters depending on customer requirements. The SCAN~LINK technology is typically used for the detection of people in the danger zone behind heavy mobile equipment, however, we are able to combine multiple sensor units to create a custom safe zone that extends around the side and front of the equipment as well.
The Display Unit is used to provide a visible and audible alert to the equipment operator that an RFID tag has been detected. Diagnostic information such as system health status is also reported to the operator through the Display Unit. The Display Unit contains a low power mesh network auxiliary transceiver that can be used to broadcast via dedicated wireless channel a detection signal directly to an alarm/indicator unit worn by the ground worker.
SCAN~LINK SAFETY APPAREL
The SCAN~LINK Armour system is able to differentiate between a person and an object using programmed, passive UHF RFID tags in the SCAN~LINK safety apparel. The passive RFID tags are located 360 degrees around the worker discreetly embedded in the safety apparel, increasing the probability of detection. Multiple RFID tags are distributed within the SCAN~LINK Armour safety apparel to improve the probability of detection. Using multiple tags means that detection of a worker becomes less dependent on their orientation as compared to a single tag style system. Personnel can be detected by the SCAN~LINK Armour System if they are wearing the SCAN~LINK Armour safety apparel and are within the detection range of the SCAN~LINK Sensor/Antenna unit. The ability of the SCAN~LINK Armour System to detect a tag will vary with tag orientation, movement, mounting surface, moisture content, line of sight and proximity to the human body.
Safety vests and hard hats are typically used for longer range 5 meter detection. The SCAN~LINK Armour system will only detect and read SCAN~LINK safety apparel and because of this the operator and worker will only be warned when a worker equipped with SCAN~LINK Armour apparel enters the detection zone and is detected. There are no “false alarms” with the Armour system.
SCAN~LINK Safety apparel should be tested regularly using a SCAN~LINK Tag Health Tester and should be kept dry and free of dirt, snow, ice and other contaminants. Proper tag mounting and orientation instructions should be followed when installing SCAN~LINK RFID Tags into Hard Hats. SCAN~LINK Safety Vests should be worn properly and fully fastened to improve front and back detection. Personnel wearing multiple articles of SCAN~LINK Safety apparel, such as a SCAN~LINK equipped Safety Vest and Hard Hat, will have a higher probability of being detected by the SCAN~LINK Armour System than those wearing only a single article of SCAN~LINK Safety apparel.
RFID cannot penetrate or “see” through steel but will also not “detect” it. The SCAN~LINK Armour system works on line-of-sight and can detect a person on the ground when he or she is in that line of sight. The SCAN~LINK Armour systems have primarily been installed on construction mobile heavy equipment operating on land development sites and road construction and have withstood these operational environments. The SCAN~LINK Armour system has been in operation in all of Canada’s harsh weather conditions with excellent results.
