Apartment phones
If apartment phones are to be connected, they should be
placed in a suitable place in the apartment (wall or table
mounting). The apartment phones are connected to the central
unit with a 4-core cable (4x0,5mm or equivalent). Instructions
on how to address and connect the apartment phones are on
page 17.
Before starting to install the system
At the back of the user manual are four charts. Make copies of
the charts and ask the system manager to fill them in
according to the instructions in the
Preparations
chapter in the
user manual. Also check that this person gets a copy of the
user manual.
Connecting-up
To connect the different components in the entrance phone
system proceed as follows:
1 Wire a 4-core cable between the central unit and each entrance
phone*. Use a 2-core cable between the entrance phone and
the electric release. This cable should be rated according to the
current of the electric release.
2 Connect the transformer to the central unit (see the wiring
diagram on page 16).
3 Connect the plug to the central unit (see the wiring diagram on
page 16).
* On installation in environments with excessive electrical
disturbances, a screened 4-core cable is adviseable to ensure
the best sound quality.
