Exclusive from Auerswald: the a/b Switching Modules
If you want to switch on lights when pressing a (bell) button or activate your existing door bell you will need additional switching contacts. Auerswald is offering the a/b Switching Modules as an exclusive solution for the TFS-Dialog 200. They can be fitted anywhere within the wiring between door phone and telephone system and will be activated upon pressing one of the buttons. Six of these a/b Switching Modules can be attached to one door phone TFS-Dialog 200; despite only one single two-wire cable is necessary. Each button of the door phone can control one or more switching modules with free selectable allocation. The modules fit easily into e.g. existing flush-mounting junction boxes.
Communication and switching using the mobile phone
Assuming you are out of the house for an errand. If the door call is forwarded to your mobile phone you can inform the person in front of the door that you will be back in a second. Or you can tell the postman where to leave the parcel. If it is a family member who has forgotten the key you can open the door with your mobile phone, switch on the light or activate other switching tasks via the connected a/b Switching Modules.
