SP-6820 Low-Frequency Card R Low
Installation Sheet (Wiegand Interface)
SP-6820 Low-Frequency Card Reader
These instructions are for AWID’s Model SP-6820 reader, using compatible proximity credentials from AWID.
Parts List
(a) 1 Installation Sheet for SP-6820
(b) 1 Model SP-6820 Reader
(c) 2 #6-32 × 1” machine screw (for single-gang utility box)
Reader Location: Select the reader’s mounting location. The SP-6820 Reader may be screwed to a singlegang utility box like a cover plate, or to a wall or other surface. On a metal surface, read range is reduced about
20%. The SP-6820 may be installed indoors or outdoors, but it needs protection from direct rain or snow.
DC Power Supply: DC power for this reader is usually supplied from the +DC and Ground terminals of the
Wiegand reader port on the system’s panel. If this is not possible, use an independent power supply. Power
may be shared with other readers if the supply has sufficient current capacity. The power supply should be
close to +12 volts DC (as low as +5 volts is OK), 1 ampere capacity, linear-rated, regulated DC output.
Cable to Controller and Power Supply: 4 to 7 conductors from the reader to the system (2 wires for DC power,
2 wires for Wiegand data, and 1 to 3 wires for external LED, Beeper/Alarm, and Hold control, if used).
22-gauge stranded wires. Overall 100% shield for both power and data. 500 feet maximum length.
 If the DC power supply is separated from the panel’s reader port, the reader’s black wire must be
connected to both the DC power supply’s Negative terminal and the panel reader port’s Ground terminal.
 If the separate DC power supply is close to the reader, run two 22-gauge cables – 2 wires for DC power,
and 3 to 6 wires for Wiegand data (including Ground) and for the external control lines, if used.
Both cables must be overall-shielded and earth-grounded (at the end far from the reader).
 Conduit: If cables are pulled through metal conduit, the conduit should be earth-grounded (like the cables).
1. Connector – Cut off the 10-pin in-line connector from the end of the reader’s cable. Discard the connector.
2. Open the Reader – Snap open the reader’s front cover by inserting a wide screwdriver blade in the slot at
the bottom edge of the cover. Twist the blade gently.
3. Wire Connections – Connect the reader’s wires to the cable(s) for power and data.
a. First, connect black to the panel port’s Ground terminal, and, if separate, to the power supply Negative.
b. Connect green to the Data-0 terminal. Connect white to the Data-1 terminal.
c. Connect the gray drain wire to the shield of the connecting cable.
If power and data are in separate cables, connect all three drains/shields together near the reader.
d. If the LED, Beeper/Alarm and/or Hold features are used, connect the brown, yellow and/or blue wires.
e. At the end of the cable(s) near the panel (and near the power supply, if separate), connect the shield to a
verified earth-ground.
f. Last, connect red to the DC Positive terminal.

4. Reader Mounting – Feed the reader’s cable through the utility box or the wall’s cable opening. Fasten the
reader to the utility box or the wall, with screws through the holes inside the open reader. Use the supplied
screws for mounting on a utility box. When mounting is finished, snap the cover on the reader.
5. Reader Test – When power is applied to the SP-6820, the LED initializes to steady-red for standby, and the
beeper sounds. With every presentation of an AWID UHF card to the reader, the LED changes color
momentarily, and the beeper sounds briefly. Read range with a compatible AWID card is up to 8 inches.
6. System Test – Wire the reader to the system’s controller. Program the code for the AWID proximity card
or tag into the host system, with full priority, all doors groups, and all time zones. Present the card or tag
to the reader. Observe door unlock or gate opening, indicating “Access Granted” by the system.
