Central Unit

This is a patented product!
The central unit of the intercom system is the result of more than 8 years of intercoms production experience and it is built in a very resistant case, with a special design.
The access is realised using a digital key.
A special feature is the infrared sensor - the names list is illuminated automatically when someone aproaches after dark.
The keys are touch type, with a very high fiability.
The central unit can control up to 144 interior units through a four wire link.
