Doorbell module with two buttons
A call button module with two buttons for the modular door station from the VTO4103 series, for two dwellings behind the same front door.
What you can count on
- Two doorbell buttons: each with a window for the resident's name
- Power supply via the main module: 5 volts, supplied by the adjacent module, so no connection of its own
- Aluminium: silver finish, IK07 and IP65
What to look out for
This module belongs to the VTO4103 series, which works on 2-wire hybrid. For the VTO4202 series there is a separate version with the same function. Check first which main module you have or are choosing.
The IP65 rating only applies once the housing has been sealed with silicone sealant during installation.

Frequently asked questions
Can I fit more modules next to it?
Yes. For more dwellings, you place several doorbell modules next to each other, until the housing is full. Make sure that you choose a housing that suits that number.
Does this module need its own power supply?
No. The modules receive 5 volts from the main module via the small cables between them. You only connect the main module.
Is an enclosure included?
No. You choose the housing based on the total number of modules in your setup, and you order it separately. Let us know how many modules you have and we will find the matching one.
