Extra bell for surface mounting

The extra bell can be added to an internal audio or video unit, so that calls never go unheard. There is a ring tone distinction between a floor call, a door call and an internal call. The ring signal can be deactivated by using the switch at the bottom of the bell. The ring volume can be adjusted during the installation. The bell will be connected to the bus system, and can be programmed in parallel with two internal audio or video units or directly to a bell push button. It is not necessary to add an extra contact or transformer.
