The telephone interface allows you to control the door phone installed in the house and thus divert the door phone calls to your mobile.
With this interface, in addition to being able to communicate, you can open the door from any landline and wireless phone. It is very useful when the owner is not at home.
Its DIN 10 format facilitates installation in electrical equipment boxes, it can also be screwed directly into the wall.
