If you want to switch on lights when a (doorbell) key is pressed, control your existing door bell, or inform your intrusion detection system about visitors at the door, then you need additional switch contacts.

 

As an exclusive connection option, you may use a/b Switching Modules which can easily be switched to any location on the signal line between the door terminal system and PBX, and initiate the switching operation when a key is pressed.
