Miniature ABAX wireless system controller

The ACU-270 controller can be used with the control panels of INTEGRA and VERSA families, allowing expansion of the system by adding wireless devices. It provides two-way communication with confirmation of all transmissions. It also allows the alarm system to be operated by means of wireless keypads as well as remote control keyfobs of the ABAX bidirectional system.

The advantage of the ACU-270 controller is its excellent range - up to 500 m in open area, obtained through the use of an advanced radio system. In addition, the ACU-270 is installed in a compact enclosure. This makes the controller practically invisible.

  • interfacing with the control panels of INTEGRA and VERSA families (connection through the communication bus)
  • support for up to 48 wireless devices of the ABAX system:
  • support for up to 8 wireless keypads within the ABAX system (depending on the control panel)
  • support for up to 248 APT-100 keyfobs (depending on the control panel)
  • two-way encrypted radio communication in the 868 MHz frequency band
  • up-to-date radio system
  • programming the controller via the control panel by using:
    • keypad in the service mode
    • DLOADX program
