ENERAL
The ACU-100 controller allows communication between any alarm control panel and the
ABAX system wireless devices. It enables wire-operated security systems to be expanded by
addition of wireless devices. The ABAX system is based on two-way communication. All
messages sent by the devices are acknowledged, which ensures that the equipment status
information will reach the controller and allows online check of the devices for their presence
in the system. Configuration of parameters and testing of the wireless devices is performed
by radio, without the need to dismantle their housings. Coded communication between the
units takes place within the frequency band of 868.0MHz – 868.6MHz.

ACU-100
WIRELESS SYSTEM CONTROLLER
The ACU-100 controller supervises and coordinates operation of up to 48 wireless devices.
The status of devices is signaled on the OC type outputs. It can also be transmitted to the
control panel through the communication bus.
The controller settings and wireless equipment parameters are programmed by means of an
LCD keypad or a PC computer.
