1. Introduction

The AY-x20 is a family of RFID proximity card readers to be installed for
use with access control systems. The AY-x20 family reads the proximity
card and transmits its data to the access control system, using common
multi-format Wiegand outputs.

3. Installation

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-x20 Reader

Before mounting, you should determine the best location for the
reader.

To mount 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 to the controller 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.

Card readers are to be used with control panels whose power
supply is UL Lis ted Class 2 or equivalent.

4. Wiring

The AY-x20 is supplied with a 10-conductor 18” pigtail.

To connect the reader to the controller:

9. 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").

10. Prepare the controller cable by cutting its jacket back 3 cm (1¼")
and strip the insulation from the wires about 1.2 cm (½").

11. Splice the reader’s pigtail wires to the corresponding controller
wires (as indicated in Table 1) and cover each joint with insulating
tape.

12. If the tamper output is being utilized, connect the purple wire to
the correct input on the controller.

13. 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

5.1 Testing

Once the reader is wired to a power supply and to the controller, you
should test the reader.

To test the reader:

1. Power up the reader.

The LED and beeper activate one time. This indicates that the
reader is working properly.

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.

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.

5.2 Output Selection

 For Wiegand 26-bit operation, the grey wire should be held not

connected.

 For Clock & Data operation, the grey wire should be connected to

the ground

 For Serial RS-232 operation, the grey wire should be held to +DC

(VIN).

5.3 LED Control

If the LED control wires (orange and brown) are not used (open), the
reader LED remains red continuously, and flashes green momentarily
when successfully reading a card.

The bi-color LED color can be controlled using the orange and brown
wires.

 When the orange wire is grounded, the LED is green
 When the brown wire is grounded, the LED is red

 When both the brown and orange wires are grounded, the LED is

amber.

5.4 Buzzer Control

If the buzzer control wire (yellow) is not used (open), the buzzer beeps
only when a card is read successfully. The buzzer can also be controlled
using the yellow wire. When the yellow wire is grounded, the buzzer
sounds.

5.5 Hold Control

The reading of cards can be disabled using the hold wire (blue). If the
blue wire is grounded, the reader ignores all cards placed in its field. If
the blue wire is open, the reader reads cards normally.

5.6 Tamper Output

This reader has an optical tamper sensor.

 When the sensor detects light, the tamper output is grounded.

 When the sensor does not detect light, the tamper output is held

to the high open collector.
