Wiring
Using an entry confirm button
Where more than one door interface can pick up the hands free token, a 'push to make' button can be used
to select the required door. Where fitted, the LED on a confirm button will flash for 5 seconds after the hands
free token has been recognised and must be pressed to unlock the door.
Once an entry confirm button has been fitted to the interface PCB, perform the following sequence:
1. Power down the interface board.
2. Power up the interface board.
3. Press and hold the entry confirm button for a minumum of 3 seconds within 60 seconds of power up.
To disable the use of the button, repeat the above sequence.

Firmware download
Hands free firmware for the P series reader will be downloaded from the interface to the reader as soon as it is
powered up. This is indicated by flashing amber and red LED's on the reader. Once complete all LED's will be lit.
This may take up to 10 minutes to complete. Do NOT disconnect power during the firmware update.
If the firmware update is still taking place after 10 minutes then remove and then re-connect the ACU cable.
Listen to the reader, the reader should NOT beep. If the reader beeps within approximately 10 seconds of
power up it will not take the firmware update. Repeat the process until the reader does NOT 'beep' on power
up. Then leave for 10 mins to allow the update to take place.
Installation
No additional power supply is required for this installation. Power is supplied by the ACU reader port.
Complete the wiring between the P series reader, the hands free module and the ACU before powering up
the ACU. This will ensure that the reader firmware is reconfigured for hands free operation.
