INSTALLATION
Four-port decoders Ref. 826/23 must be installed as shown below.
The four-port decoder must be connected:
•
To the system riser cable on one side, and
•
To the apartment stations (4 max.) on the other side.
When making four-port decoder connections to apartment stations, the
following rules must be observed:
•
Use cable with a cross-section over 0.50 mm
2
.
•
NEVER connect several conductors in parallel in order to reach
the required cross-section (e.g., multi-core telephone cable). A
single, and preferably stranded-core, conductor of appropriate cross-
section must be used.
•
Branch lines from decoder units to doorphones must not exceed 20
meters in length
•
The six connected wires must be routed at a suitable distance from
power lines (over 30 cm, where possible).
All terminal blocks are removable to facilitate maintenance operations
and are provided with fi ns to separate conductors. Terminal blocks
are removed upwards. If necessary, a screwdriver may be used as
shown.
WARNING: Removing the protective plastic cover from the
electronic circuit board will automatically void product warranty.
