Installation Sheet (Wiegand Interface)
UA-612 UHF Reader
Reader Description
The UA-612 Reader combines the technology of a UHF long-range reader for vehicle identification with small
size and easy mounting for access control. It reads the same UHF tags and cards that AWID’s LR-2000 reader
reads for automated vehicle identification. The polycarbonate enclosure contains both antenna and RF module.
The UA-612 Reader is mounted like a cover plate on a single-gang electrical utility box, or on any surface.

Installation Procedure
1. Install a single-gang utility box, or drill two no. 27 (0.144-inch) clearance holes for the reader screws and one hole
for the cable, at the desired location. Observe ADA height requirements.
2. Snap open the reader’s front cover by inserting a wide screwdriver blade into the slot at the bottom edge
of the cover, then twisting the blade gently (see Figure 1). Note: Do not remove screws inside the cover.
3. Clip off the white 10-pin in-line connector from the end of the reader’s cable. Keep the wires as long as possible.
4. Install the reader on the electrical box or other surface. Fasten the reader to the electrical box with supplied
screws (Parts Lists, item c). Hang the reader’s cover over the base reader, and snap the cover closed securely.
5. Prepare the cable to the system’s panel and power (see Figure 2). (See “Product Specifications”, below, for the
number of cable conductors.) Power and data may share the same shielded cable, or use separate shielded cables.
Use the black and red wires for the power supply. Use the black wire also for the panel’s common
or negative or ground terminal. For Wiegand data, use the green wire for Data-0, and the white wire for Data-1.
Connect the reader’s bare drain wire to the cable’s shield or drain wire; do not ground the shield anywhere – let it
float. Connect the reader’s brown wire if used for LED control, and the yellow wire if used for beeper control.
Do not connect the orange, blue and violet wires; tape or cap them separate.
6. Use an independent regulated DC power supply, 12 volts ± 10% (a battery-charging power supply is OK).
The current rating must be 1.0 ampere or more. Do not use the panel’s DC voltage terminals for reader power.
7. Apply power to the UA-612 reader. The beeper sounds, and the LED is steady red indicating standby.
8. Present an AWID UHF card or tag (same as used with the LR-2000 reader) to the UA-612 reader. The reader’s
beeper sounds with every tag read, and the LED changes to amber briefly, and then red. If the LED control wire
(brown) is connected to the panel’s terminal, the reader’s LED is green when the system authorizes door-unlock.
