What is hands free?
The hands free system increases the effective read range of a standard Paxton P or KP series reader.
The system comprises of a hands free interface, a compatible reader (see specication table) and hands free
tokens (keycard or keyfob). The system operates by using the eld being transmitted by the P series reader to
wake up the token which then communicates with the interface which contains a long range receiver.
Existing P and KP readers can be used without modication. The hands free interface takes its power from the
control unit and therefore does not require a power supply.
Hands free tokens also include a standard EM4100 proximity ID chip and can therefore be presented to any
compatible proximity reader whether they are using the hands free interface or not.

Before you install
Positioning readers
Readers should not be positioned so that their active elds overlap.
(see table on back page for typical hands free read ranges)
For example, the minimum distance between a P200 and a P50 reader should
be 3.6 m (P200 hands free range = 2.5 m + P50 hands free range = 1.1 m)
For maximum read range the hands free reader eld should not be overlapped by the eld from other
interference sources at or around 125 kHz. These include Loop readers, OEM readers, etc.
For optimum keyfob battery life please choose your reader location carefully to avoid placing it within hands
free range of work stations, rest or smoking areas.
Read in, read out
When using in and out readers, users may be picked up by both readers as they move through the door which
will reduce the reliability of any roll call or anti-passback application. Ensure that sufcient spacing is provided
between these readers for optimum range and reliability.
Positioning the interface
The interface should be positioned as close as practical to the reader. A distance from interface to reader of
10 to 15 meters can be achieved but wireless technology is susceptible to environmental factors and so if
problems are experienced it may be necessary to move the interface closer to the reader.
The hands free interface should not be housed in a metal enclosure as it contains the main receiver aerial.
Sticky feet allow the interface to be stuck to the ACU wiring label in a PSU plastic housing.

Firmware download
Hands free rmware 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 ashing 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 rmware update.
If the rmware 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 rmware 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.
Using an entry conrmation button
Where two door readers may pick up the same hands free token, a push to make button can be used to conrm
an entry request for the specic door. Where tted, the button LED will ash for 5 seconds after the hands free
token has been recognised and must be pressed to unlock the door.
To enable the use of an entry conrmation button do the following steps:
1. Power down the interface board
2. Power up the interface board
3. Press and hold the entry conrmation button for a minumum of 3 seconds within 60 seconds of power up.
To disable the use of the button, repeat the above process.
