MOUNTING INSTRUCTIONS
To mount the Reader, perform the following:
1.
Determine an appropriate mounting position for the Reader.
2.

3.
Using the template as a guide, drill two holes (hole size is
4.
indicated on mounting template) for mounting the Reader
to the surface.
5.
Drill a 7/16" (10mm) hole for the cable. If mounting on metal,
place a grommet or electrical tape around the edge of the
hole.
6.
Route the interface cable from the Reader to the Controller.
A linear type power supply is recommended.
Note: The prox reader can also be mounted using epoxy glue.
After application, the reader should be firmly held in place
until the glue dries.
Note: Card Readers are to be used with control panels whose power
supply is UL Listed Class 2 or equivalent.
WIRING INSTRUCTIONS

OPERATION INSTRUCTIONS
TESTING THE READER AND CARD READING
The Reader should be tested after wiring it to a power supply and
the Controller. Do this by performing the following steps:
1.
Power up the Reader. The LED and Beeper will activate one
time. This indicates that the Reader is working properly.
2.
Present the appropriate type of proximity card to the
Reader. The LED will momentarily flash green and a short
beep will be emitted. This indicates that the card was read
properly by the Prox Reader.
3.
After the card data is processed by the Controller, the
Controller can then turn the LED green. Refer to the
Controller description of the LED operation if the Reader LED
is controlled by the Controller.
OUTPUT SELECTION
ForWiegand 26-bit operation the grey wire should be connected
to the ground, for Wiegand 37-Bit operation the grey wire should
be held not connected, for Serial RS232 operation the grey wire
should be held to +DC (VIN).
LED CONTROL
If the LED control wires (orange and brown) are not used (open)
the reader LED will remain red continuously and when successfully
reading a card the reader will flash the LED green momentarily.
The Bi-Color LED color can be controlled using the orange and
brown wires. When the orange wire is held to ground the LED will
be green; when the brown wire is held to ground the LED will be
red; when both the brown and orange wires are held to ground
the LED will be amber.
BUZZER CONTROL
If the buzzer control wire (yellow) is not used (open) the buzzer will
beep only when a card is read successfully. The buzzer can also
be controlled using the yellow wire. When the yellow wire is held
to ground the buzzer will sound.
HOLD CONTROL
The reading of cards can be disabled using the hold wire (blue). If
the blue wire is held to ground the reader will ignore all cards
placed in its field. If the blue wire is open the reader will read
cards normally.
