AY-L23 and SA-23-B2/B4
Outdoor Long-Range RF Reader and Remote Controls
Installation and Operation Manual
1
1. Introduction
The AY-L23 is an outdoor long-range RF reader that acts as a receiver.
It is compatible with Rosslare’s SA-23 wireless remote control
transmitters:
SA-23-B2 – 2-Button Remote Control
SA-23-B4 – 4-Button Remote Control
The AY-L23 reader and the remote controls are available in both G
(433.92 MHz) and H (868.35 MHz) frequencies.
L23 is not compatible with old remote controls such as:
SA-26, SA-27, and SA- 28.
When the AY-L23 receives the a command signal from a SA-23-B2/B4
wireless transmitter, the AY-L23 outputs the ID to A_DATA0,A_DATA1
or B_DATA0,B_DATA1 to the attached controller and controls the
function of the relay (open drain FET) A or B according to the SA-23-B2
remote’s command.
The command signal consists of 3 parts:
ID (in Wiegand format)
ID output to A or B Wiegand Output according to the command in
SA-23-B2
Relay Function A or B according to command in the SA-23-B2

3. Mounting Instructions
Determine an appropriate mounting position for the receiver. Do not
mount the receiver near any source of wireless interference or on any
metal surface.
1. Peel off the back of the self-stick mounting label template included
with the unit and place at the desired mounting position.
2. Using the template as a guide, drill two holes (hole size is indicated
on mounting template) for mounting the receiver to the surface.
3. Drill a 7/16” (10-mm) hole for the cable.
4. Remove the front case from the receiver.
5. Attach the receiver to the controller. (See wiring instructions)
6. Screw the receiver’s rear case onto its mounting location and
return the front case onto the mounted rear case.
The receiver is to be used with control panels whose power supply is
UL Listed Class 2 or equivalent.

To connect the receiver to the controller:
1. Prepare the receiver cable by cutting the cable jacket back 1¼
inches and strip the wires ½ inch.
2. Prepare the controller cable by cutting the cable jacket back 1¼
inches and strip the wires ½ inch.
3. Splice the receiver’s pigtail wires to the corresponding controller
wires and cover each connection (see Table 1).
• The individual wires coming out of the receiver are color coded
according to the rec ommended Wiegan d standard.
• When using a separate power supply for the receiver, this supply and
the controller’s power supply must have a common ground.
• The cable shield wire on the receiver should be attached to an Earth
ground (best) or signal ground connection at the panel or power
supply end of the cable. This configuration is best for shielding the
receiver cable from external interference.

5. 4BOperation
The AY-L23 works with any SA-23 remote and can operate two
Wiegand data outputs connected to the reader’s inputs at the access
control panel.
The AY-L23 LED is red in Operation mode.
5.1 8BReader Mode
When pressing 1 on the SA-23-B2/B4, the AY-L23 sends Wiegand
data-A. The LED changes to green for a short time with a beep.
When pressing 2 on the SA-23-B2, the AY-L23 sends Wiegand data-B.
The LED changes to orange for a short time with a beep.
When pressing 2 on the SA-23-B4, the AY-L23 sends ID+1 on Data A
line to the controller. The LED changes to green for a short time with a
beep.
5.2 9BController and Reader Mode
The AY-L23 can operate two OC outputs A/B with the SA-23-B2.
To activate the output from SA-23-B2, the remote button’s ID should
be registered first (Section 5.3).
In Controller and Reader mode, SA-23-B4 is not in use as it
does not activate any output of the AY-L23.
When pressing 1 on the SA-23-B2, the AY-L23 sends Wiegand data-A
and activates out-A for 5 seconds.
When pressing 2 on the SA-23-B2, the AY-L23 sends Wiegand data-B
and activates out-B for 5 seconds.
5.3 10BRegistering an ID
The AY-L23 can register up to 48 IDs with an SA-23-B2.
1. Connect the orange and brown wires to GND.
2. Power on at Vin and GND.
After buzzer sounds 3 times, the LED turns green.
The AY-L23 is now in Register mode for 15 seconds.
3. Press 1 on the SA-23-B2 remote.
If the registration is successful, you hear 2 short beeps.
If the ID was previously registered, you hear 2 long beeps.
If the limit of IDs (48) is reached, you hear have 3 long beeps.
4. Press 2 on the SA-23-B2 remote.
If the registration is successful, you hear 2 short beeps.
If the ID was previously registered, you hear 2 long beeps.
If the limit of IDs (48) is reached, you hear have 3 long beeps.
Once the AY-L23 exits Register mode (after 15 seconds), you hear
a long beep.
Each of the 4 buttons of the B4 remote control is preprogrammed with an ID that cannot be changed.
5.4 11BDeleting all IDs
1. Connect the orange wire to GND.
2. Power on at Vin and GND.
After buzzer sounds 3 times, the LED turns orange for 2 seconds
and then turns green.
The AY-L23 is now in Delete mode for 5 seconds.
3. When the LED turns green, disconnect the orange wire from GND.
The LED changes from green to orange.
4. Re-connect the orange wire to GND within 5 seconds.
If all the IDs in reader are deleted successfully, the alarm
sounds 2 times and then you hear 3 short beeps.
If the deletions fails (times out), the reader outputs a long
beep.

6. Using the SA-23
The AY-L23 is used along with either the SA-23 2-button or 4-button
remote control.
The SA-23-B2 remote is programmed to:
Button 1 – Wiegand output to A DATA0/1 with A FET(relay)ON 5S
Button 2 – Wiegand output to B DATA0/1 with B FET(relay)ON 5S
The SA-23-B4 remote is programmed to:
Button 1 – Wiegand output to A DATA0/1 [ID number]
Button 2 – Wiegand output to A DATA0/1 [ID number+1]
Button 3 – Wiegand output to A DATA0/1 [ID number+2]
Button 4 – Wiegand output to A DATA0/1 [ID number+3]
6.1 Initial Setup
To set up the remote for use:
1. Install the battery.
The red LED turns on for 1 second, turns off 1 second and then
turns on for 1 second.
2. Check the distance range of the remote:
If the distance is set to long range (70 m), LED flashes on and
off 0.5 seconds 3 times.
If the distance is set to short range (15 m), LED flashes on and
off 0.1 seconds 6 times.
By default, the remote distance is set to 70 m.
6.2 Changing the Remote Distance Range
You can set the remote range to either 15 or 70 m.
To set the remote distance:
1. Remove the battery from the remote.
2. Press any button to reset the remote.
Any time you remove the battery from the SA-23, you must reset
the remote control by pressin g any key to discharge the internal
capacitors.
3. Install the battery.
4. Press 1 and 2 together before the LED flashes for a second time.
The remote toggles to the other remote distance range.
If the distance is set to long range (70 m), LED flashes on and
off 0.5 seconds 3 times.
If the distance is set to short range (15 m), LED flashes on and
off 0.1 seconds 6 times.
6.3 Changing the ID of Button 2 (for SA23B2 only)
You can set Button 2 to transmit the same ID as Button 1 or to
transmit a unique ID. By default, Buttons 1 and 2 transmit the same ID
number.
To change the ID of Button 2 to be unique:
1. Remove the battery from the remote.
2. Press any button to reset the remote.
3. Press 2 and install the battery until the red LED flashes quickly 5
times for 0.1 seconds.
Button 2 will now use transmit a unique ID (ID of Button 1 +1)
4. Close the cover.
To change the ID of Button 2 to use ID of Button 1:
1. Remove the battery from the remote.
2. Press any button to reset the remote.
3. Press 1 and install the battery until the red LED flashes quickly 5
times for 0.1 seconds.
Button 2 will now transmit the same ID as Button 1.
4. Close the cover.
