A. PURPOSE
While preparing to install AWID’s UHF long-range readers and credentials, the steps below will guide the installers.
To start a new project, see AWID’s “Support 1 –Getting Started”. It helps to assure that the correct products are ordered
and collected for the client’s application.
B. GUIDELINES
1. First thing –Know the client’s goals and desires. Know what will work, and what needs to be changed.
2. Study the site’s layout. Make plan drawings. Get architect’s prints. Take photographs.
3. Define the roadway so that all vehicles follow the same path –one lane wide. Mark the lane if necessary.
4. A vehicle-length between the reader and the gate may allow the gate to open before vehicles roll up to the gate.
5. Ideal vehicle speed may be 15 miles per hour. This should assure time for reliable reading of all tags.
6. If possible, select a reader location where the vehicles travel in a straight line as the tags are read.
7. Know where to mount the reader –at the side of the roadway, or above the roadway, or facing turning vehicles.
8. Plan on reader height that relates to the physical structure, vehicle types, tag type and location on vehicles.
9. Assure that there is open space between the reader and the tags –no fence, bushes, structure to block the UHF.
10. If vehicles will have access to more than one gate, the arrangement of reader and tag locations must be consistent.
11. Mount the reader using an adjustable-head bracket. The reader must be aimed at the location of tags for reading.
12. At the reading distance, have the reader and tags aligned with each other –facing each other, in parallel planes.
13. Watch for conditions that may require the “HiLo”dual-antenna reader set, or a protective housing for readers.
14. Scan the site for radiation that might affect reading. Use the Installation Kit’s “ProHunter”RF Signal Detector.

C. GOOD PRACTICES FOR ALL UHF READER INSTALLATIONS
1. Use only overall shielded cable (100% rated) for reader’s power and data, and for door locks and gate operators.
2. A reader’s power and data may share the same cable, or run in separate cables. Use AWID’s cable specifications.
3. Use a separate shielded cable for each reader. This helps to prevent cross-talk in long cable runs.
4. Never connect 2 or more readers in parallel into the same power wires or data wires of the cable.
5. Never connect 2 or more reader cables in parallel into the same port on the panel, or into the same power supply.
6. When making power connections, connect negative DC first and positive DC last. Disconnect in reverse order.
7. Remove DC power before cutting wires and before making data wire connections. Never bunch-cut hot wires.
8. Feed Wiegand Data-0 and Data-1 wires in different pairs of twisted-pair cables, to prevent data crosstalk.
9. UHF readers have no audible or visible indicators. Use the Installation Kit’s test unit for beeper and LED.
10. UHF readers are wired differently from proximity readers with the same Wiegand interface. Use the diagrams!
11. UHF readers must not be grounded or tied together. Let DC power, drains and shields float.
12. Unused wires must be taped or capped separately at the reader, insulated from ground and from other wires.
D. TOOLS AND SUPPLIES
For installing and trouble-shooting the AWID UHF readers, the following tools and devices are always very useful.
·AWID’s LR-KIT-0-0 Installation Kit –a required first-time, one-time purchase for every installing company.
·Back-up battery, 12 volts, 7.5 ampere-hours, fully charged (to substitute for DC power supply and power cable).
·Proximity reader and compatible card (to substitute for the UHF long-range reader and data cable into the panel).
·Spare tags or cards from the client’s supply for users (with codes programmed into the system).
·Digital DC meter with ranges for 20 volts or more, and 5 amperes or more.
·Camera tripod, with camera seating pad (1/4”-20 screw).
·Common hand tools and wiring supplies.
·If available –dual-trace oscilloscope, and UHF spectrum analyzer with directional and 360-degree antennas.
E. DOCUMENTS FOR REFERENCE
·Quick Installation Guide for the AWID UHF long-range reader model to be installed.
·“Installation & Operation Manual”for the AWID UHF long-range reader model (available on AWID’s Web site).
·Technical Reference issues describing special conditions for this application –installing the reader inside a
protective housing, tags on big trucks or forklifts, and others. See Technical References in AWID’s Web site.
·Instructions for the UHF tags and cards.
·Quick Installation Guide and product sheet for the LR-KIT-0-0 Installation Kit.

F. TESTING THE INSTALLATION SITE
The LR-KIT-0-0 Installation Kit supplies the means of testing and evaluating the environment into which the UHF
long-range reader will be installed. These tests can be run without interface to any access control system or controller.
1. With the “ProHunter”RF Signal Detector from the Kit held in your fingers, scan the area around the planned site
for the reader. Watch for indications of spurious RF radiation from a neighboring source. This may be a cell
phone tower, communications antenna, another UHF reader, arc-type lighting fixture (including fluorescent),
buried loop sensor, or security camera. (Such extraneous radiation may not interfere with the AWID readers.)
2. Set up the Kit’s “EVAL”reader. Clip the Kit’s Test Unit to the EVAL reader. Clip the Kit’s plug-in DC power
module, or a back-up battery, to the EVAL reader’s wires. To arm the EVAL reader, connect its yellow wire
to the black wire. (A camera tripod is very convenient for supporting the reader during testing, hands-free, up to
a height of 6 feet.) See Figure 1 (page 4) for clip connections –black, red, orange and yellow wires.
3. Read a single tag or card from the Kit, or from the client’s supply. Measure how far that tag can be read in front
of the EVAL reader. Hold the tag or card as instructed. Have all other UHF tags far behind the EVAL reader
to prevent inadvertent reading of other tags.
4. If the tests indicate less than rated reading distance for the reader and credential models –
(a) Move the EVAL reader around to other locations at the installation site. Find an alternative RF-quiet area.
(b) Remove power from all other devices that may generate interfering radiation. Look for improved tag reading.
(c) To test the Kit’s components without interference, carry the test gear to a remote location free of RF sources.
5. To test-read a credential in or on a vehicle, secure a tag temporarily by tape. For a WS-UHF windshield tag, press
it inside the windshield glass using a fist-size block of plastic foam. This flattens the WS tag against the glass.
6. Invite the client to observe these tests, for confidence in good performance of the products before installation.
G. SHOP-TESTING AWID’S PRODUCTS
When the AWID products arrive, open the packages, account for all items, and know the purpose of each item.
Before taking them to the site for installation, use the Installation Kit to see the reader, the tags, the power supply,
and other system components working in the friendly environment of your own shop.
1. Hang the reader on a wall or shelf, about 6 feet high, with plenty of clear space in front of the reader. If possible,
use a driveway or parking lot. A ¼”-20 screw inserted in the reader’s back surface is convenient for quick testing.
2. Follow the same procedure as in Section F, except substitute the reader that will be installed, in place of the Kit’s
“EVAL”reader.
3. To see the reader’s data in an access control system, connect the reader’s 3Wiegand data lines (green, white
and blue) to the reader input port on your shop’s controller panel. Use the wiring diagram. Observe code inputs
for a test tag, with the tag held in your fingertips, far to the side of your body, out to the rated reading distance.
4. Use this procedure to build confidence in the operation and performance of the products, and in your own ability
to install the products quickly and correctly at the site. Call AWID with questions.
H. CLUES FOR GOOD TESTING
1. Hold the test tag or card in your fingertips, at arm’s length beside you, with a flat side facing the reader.
2. Have just one tag or card in front of the reader. Move all other tags far behind the reader.
3. Start by holding the tag or card close to the reader. Gradually move the tag away from the reader, in
front of the reader, moving the tag up and down, back and forth, to map the extent of the working field.
