Power Supplies, Relays and other Accessories
The power supplies are used to provide the current and voltage necessary to operate the different elements of an intercom or video intercom installation. Each feeder is used in a specific place in the installation.
A relay allows you to perform additional functions such as opening a second door or garage door and activating stair or courtesy lights.
Video changers are used when there are two video entrances, for example a main door and a second portal door.
Decoders are used in systems that combine several panels, for example in urbanizations with VDS panels in interior blocks and MDS panels in general entrances.
