The Multi Tenant Module for D21x IP Video Door Stations allows you to connect up to 14 third-party call buttons from almost any call button manufacturer.
Call buttons connected to the digital inputs of the MTM14E for button switches (“E, E“) must be potential-free.
In case the call button does have illumination, only LED illumination is supported since light bulbs with filament consume too much power to the module.
If you want to connect a door chime, please use the DoorBird IP Door Chime A1061W or DoorBird IP Video Indoor Station A1101. Connecting an analog door chime to the digital inputs for the button switches (“E, E“) is not supported.
