Connecting an external doorbell and / or an actuator (e.g. door opener)
To connect an existing doorbell or actuator via existing cabling you will need to have at least two
pairs of wires available. These might come from an additional power supply unit or from the bell
transformer (1). Use an ammeter to check whether there is sufficient voltage for the power supply.
Important!
Be careful not to exceed the maximum voltage for the relay
Connect the first pair of wires to the connector block V-/V+. When working with DC voltage, please
observe the correct polarity.
Connect one of the second pair of wires to the doorbell and / or actuator and the other to the connector
block (C1/B1). Connect a separate wire to the doorbell and / or actuator and the connector block (C2/B2).
Safety notice on use of a door opener
The relay (B2/B1) is a simple potential-free relay. It can be triggered manually by pulling
off the intercom and connecting the wires manually. We therefore advise you not to use
this relay for a door opener connected to the outside doors of your home. Should you still
wish to connect it, please ensure that your outside doors are locked whenever you leave
the house.
Connecting to an LAN network
In order to connect the intercom with a network cable, use either the network connector cable provided,
an existing cable, or another free network cable. Connect the cable to the network connector block
according to the colour-coding below.
