4.6 Connecting device
4.6.1 Important notes
▪ Before connecting the device to the PBX system, switch off all required
components (PBX system, device, bell transformer).
▪ When wiring, ensure that the input voltage is correct (9-24 V). The polarity
can be ignored.
▪ Do not insert the wall power supply into the socket until all cables 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 [
} 16]).
▪ 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.
4.6.2 Wiring
Use commercially available telecommunication cables for the installation wir-
ing.
Please note that in order to meet general safety provisions and to avoid inter-
ference influences, the low-current telephone lines must be routed separately
from power lines.
Observe a minimum distance of 10 cm between both types of lines. If one of
the connected lines is routed out-of-doors, you will have to provide sufficient
lightning protection.
