ABAX 2 wireless system controller

ACU-280 provides two-way, encrypted (AES standard) communication in the 868 MHz (or 915 MHz)* band - all radio transmissions between components of the ABAX 2 system are acknowledged. It works together with the INTEGRA, INTEGRA Plus, VERSA and PERFECTA 64 M control panels, enabling wireless devices to be added to the alarm system.

Because of its small size, it requires little space for installation.

The device meets the high EN 50131 requirements for Grade 2.

An advantage of the controller is its excellent transmission range, which can be up to 1600 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.

The controller can be programmed via the control panel, a keypad, or the DLOADX or PERFECTA Soft configuration programs. For advanced diagnostics of the wireless system operation, the ABAX 2 Soft program is used. Configuration, as well as firmware upgrade and testing of enrolled wireless devices are carried out by radio, without having to demount them.
