Access Control Kit CA-2 Mini and ATF-12 4+N by Auta
Audio Switch Kit 730180 + Source 715503
This kit is made up of references 730180 (CA-2 Audio Switch) and 715503 (ATF-12 Power Supply).
The switch allows you to connect up to 2 access doors with Auta analog panels in 4+N systems. It has 2 different operating modes: the factory default, in which a call ends if another one enters; and a second mode of operation, in which if a second call comes in, the switch remains on the original one until it ends.
The ATF power supply is 12V and its mounting is on a DIN rail or surface.
