LY-8M BI intercom with lowered doorbell
The handset from the intercom has an established reason, so that it can be used as a replacement for old models without fear of visible traces of their installation. This button is illuminated by an LED indicating a call. The next button allows you to control an external source, for example, the drive of the entrance gate or the lighting of the stairwell. It is possible to install a push-button module to control another external device.
