5. INSTALLING THE DOOR UNIT
• Decide the best place for the installation of the door
unit. The attachment surface should be as flat as
possible; otherwise the unit will not fit properly onto
the wall plate.
• It is advisable not to install the unit onto a metal
surface or near other possible sources of interference,
which could have negative influence on the system.
• Mark the spots to drill holes at, by making use of
the holes in the plate, as shown in figure 4, and
attach the plate to the wall. You can use the supplied
screws and plug for the attachment of the plate.
5.1 Connecting the power supply to the door unit:
The door unit can be powered in two ways.
1. Using batteries.
2. Using external power adapter.
1. Using batteries:
Insert 4 AA-alkaline batteries, keep in mind the right polarity + and -, in relation to the
contact springs in the battery compartment. Use only new full alkaline batteries for reliable
function (do not use rechargeable batteries).
2. Using external power adapter:
It is also possible to connect the door unit to the supplied external power. Connect the
wires of the power adaptor to the connectors (terminals) at the backside of the door unit
(5), these are marked with the
door unit, then the batteries take over the function in case of power failure. Check the
condition of the batteries regularly. Replace old batteries immediately. When an external
power adapter is connected, the name illumination on the door unit will get activated
automatically when it gets dark outside.
5.2 Connecting an electric door opener (optional):
• It is necessary for the installation of the electric door opener, that the door unit will be
supplied with external power; otherwise the door-open function will not be active and
therefore not usable.
• There are different connectors (terminals) on the backside of the door unit, for the
installation of the door opener (maximum load 12V/1A). The voltage on these connectors is
the same as that of the connected power adapter.
1. Always closed contact. This contact is always closed, and when the door-open button
(11) on the handset is pressed, the contact shall be broken temporarily.
2. Always open contact. This contact is always open, and when the door-open button
(11) on the handset is pressed, the contact will temporarily close.
