POWER SUPPLY OPTIONS
The device can be powered using the DoorBird power-supply unit (mains adaptor) (Option 1) or via PoE
(Power over Ethernet) using a network cable (Option 2). The device can be alternatively also be supplied with
power using a DIN-rail power supply unit that you can obtain direclty from us.
The device does not use battery power.
OPTION
Power supply using the power supply unit
(mains adaptor)
The power supply unit (mains adaptor) has a
cm long cable with two insulated wires.
Do not plug the power supply unit into the
N OT IC E
wall socket yet. Only use the original
DoorBird power supply unit or a DIN-rail
power supply unit that you can obtain from us
separately, since this has been specially
stabilized electrically and is equipped with
an integrated audio inter ference reduction
device. Other power supply units may
destroy the device or cause poor
transmission quality. The warranty expires
automatically if you use a different power
supply unit.
CONNECTING THE DEVICE
It is possible to connect the cables and wires to the device conveniently and safely via labelled connection ports.
You can connect all necessary cables and wires to the device now. Please remove any cables and wires from the
connection ports of the device that you do not need. Remove about 5 mm of insulation material at the end of
the wires that you would like to connect to the green screw connection terminal of the device.
Please take care when connecting the cables
N OT I C E
and wires. Connecting the cables and wires
the wrong way may damage the device.
Wires without insolation material must not
protrude out of the green screw connection
terminal, it may lead to electrical short and
damage the device.
The yellow, green, and red cables that lead
N OT I C E
out from the side of the Main Electrical Unit
must only be used to connect components
certified by Bird Home Automation.
OPTION
Power supply and network connection
using PoE (Power over Ethernet)
300 To power the device via a PoE-Switch (e.g. D-Link
DGS-1008P) or PoE-Injector (e.g. DoorBird Gigabit PoE
Injector A1091) in accordance with the PoE standard
IEEE 802.3af Mode A, the four wires bearing the
numbers 1, 2, 3 and 6 of a Cat.5 cable or better are
to be used. A Cat.5 cable or better must be used
as network signals can only be transmitted over
completely insulated, shielded and twisted cables.
If you use PoE as a source of power the four wires for
PoE then simultaneously form the data link.
The device won't start if your PoE-Switch/PoE-Injector
does not support the PoE Standard IEEE 802.3af
Mode A (see Diagnostic-LED and Diagnostic-Sounds).
1. Disconnect the PoE-Switch or PoE-Injector
from the power grid.
2. Run the network cable to the installation
location of the device.
Handle the front panel with care. The surface
of the front panel could be scratched or
otherwise damaged if handled without care.
You can use the nylon cord
to temporary fix the front
panel to the mounting
housing (backbox) while
connecting the cables and
wires to the device.
