NSTALLATION
The ABAX two-way wireless system should be installed so as to ensure a suitable
level of radio signal from devices working together with the controller. This will allow
the communication problems to be avoided.
All electrical connections may only be made with power supply disconnected.
Before proceeding to the system installation you should plan the arrangement of all the
devices. The installation place for the controller should be chosen so that all devices to be
supervised by it are within its range. It is recommended that the controller and the wireless
devices be mounted at a high position, which will enable a better range of radio
communication to be reached, while avoiding a risk of incidental masking of the controller
and devices by people moving around the facility.
Before permanently mounting the system components, you should check the level of signal
received by the controller from individual devices. If the signal level from a particular unit is
too low (less than 40%), a change of the device position will be necessary. At times, it is
sufficient to move the device some ten to twenty centimeters to get a significant improvement
of the signal quality. Having reached the optimal level of radio signal from all devices, you
can proceed to permanently mounting them in position.
The ABAX system radio communication has been designed so as to enable several ACU-100
controllers to work within each other's range. Synchronization with the wireless systems
already in use is always performed when the controller is switched on, and after each
operation of addition/removal of supported devices. The synchronization is performed
automatically. The number of wireless devices already working within the range of each other
depends on the R
ESPONSE PERIOD
(see D

OPTIONS AND COMMANDS
)
and can vary from 150 to 450. The higher the response frequency, the lower the number of
devices that can work within each other's range.

NSTALLATION OF
ACU-100
WIRELESS SYSTEM CONTROLLER
The ACU-100 controller should be installed indoors, in spaces with normal air humidity. Its
electronics board is mounted in the
OPU-1 A
plastic housing. Before fastening the controller
to the wall, make inlets/outlets in the rear wall of the housing for cables to connect the
controller to the control panel or ACX-100 expansion modules.
Caution:
The cables should not be laid in the close vicinity of the antenna, as this may cause
radio communication interference.
If the controller is not used together with the INTEGRA series control panels, it requires the
LCD or computer to be connected for registration of the wireless devices and software. Such
connections are temporary, for the time of programming or diagnostics.

KEYPAD TO THE CONTROLLER
If the ACU-100 controller is to be programmed by means of LCD keypad, the keypad must be
connected to the RJ-11 socket with four-wire cable. Connection of the keypad communication
bus to the RJ-11 socket is shown in Fig. 3.
Address of the keypad to be connected to the ACU-100 controller must be set as 0.
