The A22 is a 2-door controller using the ATRIUM technology. The flexibility of the ATRIUM system allows it to control up to 500 doors, thanks to its free software.
The A22 has a built in web browser, an integral power supply and includes an RS485 communication bus with automatic detection (no risk of errors due to lack of jumpers or DIP switches). The "quick start-up" programming cards allow for easy and quick programming.
The A22 is delivered and built in a metal case for security while giving ample room to make connections.
