2N Floor Annunciator

System for Informing People in a Lift

The 2N Floor Annunciator is a simple communication device designed for installation in lift cabins. Its main function is to inform the people in the cabin of the current floor number every time the lift stops. In addition to announcing the floors, it also announces the subsequent direction of travel, and warns not only of closing and opening doors, but also overloading of the lift cabin.

Product highlights:

Our customers, e.g. the operators of shopping and business centres, regularly use floor annunciators to play advertising messages in a lift. It also allows them to announce the names of the companies on the current floor and greet visitors with a welcome message, e.g. from a specific tenant.
