Call button with four buttons on a half module
Four call buttons on a half module for the VTO4202 series: four homes in half the space.
What you can count on
- Four buttons on a half module: the most compact layout for small numbers
- 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 VTO4202 series, which works on IP with PoE or 2-wire. For the VTO4103 series there is a separate version with the same function. So first check 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
Do the buttons remain easy to use?
Yes, but they sit closer together than on a full module. For a location where many older visitors are expected, a more spacious layout is more comfortable.
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.
