4. Wiring Instructions
The unit is supplied with a 22-inch pigtail, having a 6-conductor
cable. To connect the unit to the controller, perform the following:
Prepare the unit's cable by cutting the cable jacket back 1¼
inches and strip the wire ½ inch. Prepare the controller cable by
cutting the cable jacket back 1¼ inches and strip the wire ½ inch.
Splice the unit’s pigtail wires to the corresponding controller wires
and cover each connection.
Refer to the wire color table below, and to the wiring diagrams
provided on the following pages.

Tamper
If the tamper output is used, connect the purple wire to the
correct input on the controller when used as a reader, or to a
zone input of an intruder alarm system when used as a controller.
Trim and cover all unused conductors.
Note:
• The individual wires from the unit are color-coded according
the Wiegand standard.
• When using a separate Power Supply for the Reader, this
Power Supply and that of the Controller must have a
common ground.
• The Reader’s cable shield wire should preferably be
attached to an earth ground, or a signal ground connection
at the panel, or power supply end of the cable. This
configuration is best for shielding the Reader cable from
external interference
