ABAX 2 wireless system controller

ACU-220 uses the 868 MHz (or 915 MHz*) radio band, in which 4 channels have been allocated. Communication between components of the ABAX 2 system is encrypted (AES standard) and two-way, all transmissions being acknowledged. The controller works together with the INTEGRA, INTEGRA Plus, VERSA and PERFECTA 64 M control panels (connection via communication bus), making expansion of the alarm system possible by adding wireless devices. It can also interact with any other alarm control panel, automation controller (when using programmable zones and outputs of the module), or work in stand-alone mode.

ACU-220 meets the high EN 50131 requirements for Grade 2.

An advantage of the controller is its excellent transmission range, which can be up to 2000 m in the open area, depending on the device working with the controller and their operating conditions. Such good communication parameters are obtained thanks to the use of a modern radio system and antenna diversity. Depending on the level of received radio signal, ACU-220 automatically selects the optimal antenna to be used to receive the transmission.

The system settings are configured in the ABAX 2 Soft program, which is installed on the computer and has also extensive diagnostic capabilities. When working with the INTEGRA, INTEGRA Plus, VERSA or PERFECTA 64 M control panels, the DLOADX or PERFECTA Soft program or a keypad are used for the configuration. The settings can be changed and the firmware of enrolled wireless devices can be updated by radio, without having to demount them.
