DESCRIPTION
RJ45 jack to connect a standard Network cable Cat.5 or better, coming from the Internet
Router/PoE-Switch/PoE-Injector.
Do not power the device simultaneously via the power supply from the power
NOTIC E
supply unit (mains adaptor) and the power supply via PoE.
Bi-stable latching relay #1, max. 24 V DC/ AC, 1 Ampere. Security feature: The relay keeps
its state even in the case of loss of power. You can configure the default state of the relay
(open/close) via the DoorBird App. These ports can be used to connect e.g. an electric door
opener. The device does not supply power to the connected device. The power supply for
the electric door opener must be installed separately.
When wiring an electric door opener directly to a door station, there is a risk that
the electric door opener could be tampered by unauthorized third parties (e. g. by
breaking the door station and short-circuiting the wiring of the door opener).
Therefore, we generally recommend the use of a remote safety relay mounted
indoors (e. g. DoorBird I/O Door Controller A1081) for wiring an electric door
opener for a more secure installation in your home.
