The Net2Air wireless reader modules consist of two parts. The ACU module and the Remote module. The ACU
module is plugged into the reader port of the control unit. The Remote module is located at the distant location
and contains a reader port and a lock relay that replicates the switching of the ACU’s own relay.
A 12V DC power supply is required for the remote module. This may also be used for lock power.
This module repeats the basic input and output functions of the ACU.
The unit has a reader port (8 way plug and RJ45), power input and relay connection. Mount the unit and then
wire in the remote equipment (reader, lock, etc). A suitable 12V DC power supply is also required.

This module plugs directly into the reader port on the ACU. If the relay position is also to be repeated by the
remote module a VOLT FREE loop connection should be made between the relay condition input and the COM
and NO contacts on the controller relay. (See Wiring section)

Operation
NOTE: The module provides the power for this detection circuit. No voltage or diode should be connected at the
ACU control relay or either PCB may be damaged.
The typical range in an ofce environment is 5 yards. Where there is clear ‘line of sight’ across an open space,
(warehouse roof void, car park, etc) a range of 30 yards is possible. (See Wireless limitations)

Wire the relay condition input across the COM / NO of the relay
to be monitored. This will vary with ACU style.
NANO - Do NOT use the powered Lock connection on this ACU.
The module monitors volt free relay connections.
The lock is wired across 12V and COM. A 0V link is then required to complete the circuit. This will be wired from 0v
to NO or NC depending on lock type (Fail Open / Fail Closed)
A diode is supplied which should be tted across 12V and COM (Silver end to 12V ) to protect the relay contacts.

Radio Frequency Selector
Mode Button
Power up the remote unit and the 3 LED’s on the reader (repeated next to the reader port on the module) will
cycle showing that no ACU module is currently paired with this unit. The Blue network LED will ash indicating
that the module is looking for an ACU module to pair with.
Plug in the ACU module and power up the controller. the Blue LED will start to ash, indicating that it is searching
for remote modules.
Press the button on the ACU module to turn on the Mode LED (Amber). This unlocks the system to register any
remote module that is not already paired. When this is successful, the remote module reader LED’s will stop
cycling and display a steady indication.
To secure the system, the button on the ACU module should be pressed once again to turn off the Mode LED. This
will also happen automatically after 10 minutes.
Installation
Multiple unit installation
One ACU module is able to register up to 7 remote modules. Each module should be powered up in turn and will
be registered automatically by the ACU module, providing that you have set the Mode LED to be on.
DO NOT alter the rotary switch setting unless there is radio interference. (See later notes). This switch is used to
alter the radio frequency used by Net2Air and is NOT a unit selection switch.
Loss of signal
Loss of power
Wireless limitations
The system uses a 5 second heartbeat to conrm that the two modules are still paired successfully. If this check
fails, the reader LEDS will cycle while it tries to re-establish the link. If this is a regular occurrence, the modules
may need to be re-sited to rectify this situation.
If there is a power failure at either module, they will automatically re-establish communication once the power has
been restored. The relay in the remote module will RELOCK while there is no communication taking place.
All wireless communication will be inuenced by the ‘Multi path’ effect. In essence it is one radio signal being split
into several signals each time it is reected by an object. These signals arrive at slightly different times at the
receiver which then has difculty in determining the content of the original data.
Floors, ceilings, desks, shelving etc will all contribute to these reections and so the following general rules should
be adopted to reduce this effect to a minimum.
- In an ofce environment, you should mount the modules mid way between the desk height and the ceiling. This
will minimise the reections from either surface. With higher ceilings, mounting a module one arms length above
head height is a good guide. This keeps the signal above human trafc and also avoids surface reections.
- Avoid corner or ‘dead end’ locations as the signal will be reected by the multiple surfaces.
- Where possible, mount module pairs on walls that are facing each other as this maximises the ‘line of sight’ that
can be achieved.
Fixed obstructions. These will be walls, racking, cabinets, etc. They are often made of metal or have a metal
reinforcement that will block the data signal.
Moveable obstructions. These include storage bins, vehicles, people, etc. You need to be aware of this if trafc
levels vary on a daily basis. Again we are trying to maintain a clear line of sight between the two radio modules.
Compatible with hands free tokens
Where hands free operation is also required, the hands free interface must be installed between the P series
reader and the wireless remote module. (for wiring, see instructions included with the hands free interface)
During installation, allow the hands free interface to upgrade the P series reader to hands free operation. Once this
has been done, any further LED indications will be as per this document.
Microwave ovens, bluetooth and wi- networks, halogen display lighting and other high enegy devices can all
interfere with wireless communication. Try to mount these modules away from such sources.

The radio frequency channel used for the Net2Air transmissions can be changed on the ACU module by means
of a rotary switch. This does NOT need to be changed where multiple units are in use on the same site. It
provides alternative channels where RF interference is suspected as causing difculties in maintaining a reliable
radio signal.
