It is the aim of the invention to provide a door intercom and bell system making it possible to provide additional functions besides the bell and largely avoid additional wiring. This aim is achieved in that the keypad and the call system in the dwelling are connected via a bus system to a microcontroller and electronically controlled indicators are fitted as identification plates. The invention relates to a door intercom and bell system with a keypad having at least one identification plate.
L'invention vise à mettre au point un système de portier et de sonnette qui permette d'intégrer d'autres fonctions que la sonnerie et d'éviter, dans une large mesure, des câblages supplémentaires. A cet effet, le clavier et le dispositif d'appel montés dans l'appartement sont reliés à un microcontrôleur par l'intermédiaire d'un système de bus et les plaques d'identification se présentent sous forme de voyants à commande électronique. L'invention concerne un système de portier et de sonnette comportant un clavier pourvu d'au moins une plaque d'identification.
