Operation 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 ACUs own relay. A 12V DC power supply is required for the remote module. This may also be used for lock power. The typical range in an office 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) ACU module 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) 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. LED indications Blue Amber Green Net2Air network activity (Transmit or Receive) Mode - The system is unlocked to allow a remote module to be registered. A token has been presented at the remote module. Remote Module 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. Cable extensions Readers can be extended using Belden CR9540 10-core overall screened cable. The maximum length is 100 yards.

LABEL HERE 0889 Network Fail closed release Reader Wireless reader module 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 fitted across 12V and COM (Silver end to 12V ) to protect the relay contacts. Installation Power up the remote unit and the 3 LEDs 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 flash 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 flash, 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 LEDs 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. 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 The system uses a 5 second heartbeat to confirm 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. Loss of power 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. 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. Wireless limitations All wireless communication will be influenced by the Multi path effect. In essence it is one radio signal being split into several signals each time it is reflected by an object. These signals arrive at slightly different times at the receiver which then has difficulty in determining the content of the original data. Floors, ceilings, desks, shelving etc will all contribute to these reflections and so the following general rules should be adopted to reduce this effect to a minimum.
- In an office environment, you should mount the modules mid way between the desk height and the ceiling. This will minimise the reflections 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 traffic and also avoids surface reflections.
- Avoid corner or dead end locations as the signal will be reflected 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. Microwave ovens, bluetooth and wi-fi networks, halogen display lighting and other high enegy devices can all interfere with wireless communication. Try to mount these modules away from such sources. 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 traffic levels vary on a daily basis. Again we are trying to maintain a clear line of sight between the two radio modules. Radio frequency 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 difficulties in maintaining a reliable radio signal.
