Important notes
▪
Before connecting the device to the PBX system, switch off all required
components and those connected to the DoorLine (bell transformer, power
unit).
▪
When installing the wiring, ensure that the polarity (12 V DC voltage) of the
two wires in the terminals is correct.
▪
Do not insert the wall power supply into the socket until all wires are firmly
connected and there is no risk of a short circuit of wire pairs.
▪
A bell transformer (e.g. 12 V alternating voltage) must not be used as a
power supply for the device. This can result in destruction of the device!
▪
Both integrated relay contacts connect potential-free, i.e an additional bell
transformer is required to activate a door opener. Then connect the bell
transformer voltage via the respective relay switching output to the door
opener (see chapter Connection example for a door opener and a door
bell [
19]).
▪
Both switching relays can be loaded to a max. of 24 V AC / DC 1 A. Prior to
initial operation of the device, ensure that these values are not exceeded
by your door opener, door bell or other devices to be connected. Observe
the Operating Instructions of the respective products.
