Intercom system sets from COMELIT

Our mailbox systems are also available with pre-installed audio and/or video sets from COMELIT on request. Connection is very simple using two-wire technology, which means that existing cables from older systems can be used directly. No additional costs for new wiring and plastering or painting work! Instead, two wires are simply laid from the new power supply unit in the meter cupboard to the built-in loudspeaker in the function box, plus two wires from the power supply unit to the door station in the respective flat (if not already present).

Easy installation with the universal adapter
for intercom mounting

The GC-110, GC-120A and EBOX speech mesh are equipped with our self-adhesive universal adapter. It makes it possible to move the loudspeaker and microphone very close to the front of the system in order to avoid feedback and other transmission interference. The adapter is fitted on site by the electrician and is compatible with all commercially available built-in speakers.
