1. Introduction
The AY-x25B is a family of MIFARE ID read-only proximity readers that
are intended primarily for use in access control system applications. The
AY-x25B family reads the MIFARE Card Identification Number and
transmits it to the access control system, using common multi-format
Wiegand outputs.

Installation of an RFID reader adjacent to metallic surfaces
might alter the reader’s specifications. To diminish this
interference, use a plastic spacer when mounting the reader.
3.1 Installation Kit
The installation kit consists of the following items to be used during
the installation procedure:
One mounting template
Two pan head screws and wall plugs
One L-shaped security screw tool
One security screw
3.2 Mounting the AY-x25B Reader
Before mounting, you should determine the best location for the
reader.
1. Peel off the back of the self-adhesive mounting label template and
place it at the required mounting location.
2. Using the template as a guide, drill two holes (sizes indicated on
the template) used for mounting the reader onto the surface,
3. Insert a suitable wall plug into each hole.
4. Drill a 10-mm (7/16”) hole for the cable. If mounting on metal,
place a grommet or electrical tape around the edge of the hole.
5. Wire the reader as described in Section 4. A linear type power
supply is recommended.
6. Remove the reader's snap-off front cover to reveal the two screw
holes (see Figure 2 ).
Figure 2: Removing the Top Cover
7. Align the two holes of the reader with those drilled in the wall and
firmly attach the reader to the wall with two screws, whose size is
indicated on the template.
8. Relocate the front cover onto the reader.
The reader can also be mounted using strong epoxy glue. After
application, the reader should be firmly held in place until the
glue dries.
4. Wiring
The AY-x25B is supplied with a 6-conductor 46-cm (18”) pigtail.
To connect the reader to the controller:
1. Prepare the reader cable by cutting its jacket back about 3 cm
(1¼") and strip the insulation from the wires about 1.2 cm (½").
2. Prepare the controller cable by cutting its jacket back 3 cm (1¼")
and strip the insulation from the wires about 1.2 cm (½").
3. Splice the reader’s pigtail wires to the corresponding controller
wires (as indicated in Table 1) and cover each joint with insulating
tape.

Black Ground
White Data 1/Clock
Green Data 0/Data
Brown LED/buzzer control
Purple Tamper
4. If the tamper output is being utilized, connect the purple wire to
the correct input on the controller.
The LED control may be configured by the factory to function
either as a LED control or as buzzer control. When connecting the
wire to “Ground” it will activate the function continuously, either
continuous LED or continuous buzzer.
5. Trim and cover all unused conductors.
• The individual wires from the reader are color-coded according the
Wiegand standard.
• When using a separate power supply for the reader, this supply
and that of the controller must have a common ground.
• The reader’s cable shield wire should be preferably 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
5. Operation Instructions
Once the reader is wired to a power supply and to the controller, you
should test the reader.
1. Power up the reader.
The LED flashes green and the beeper sounds three times
indicating that the reader is working properly. The LED returns to
its idle state (red).
2. Present the appropriate type of proximity card to the reader.
The LED momentarily flashes green and a short beep is emitted
indicating that the card was read properly by the reader.
The reader transmits the card's data to the controller. The
controller checks the data. If it is valid, the LED changes
momentarily to green and then returns to its idle state (red).
