Installation Instructions
BUS-SYSTEM
Line network
Two common weak current
telecommunication lines may be used for
the CTC-Duo Plus Bus system, such as
J-Y (St) Y.
The power lines have to be routed in
accordance with the standing specifications.
Heavy and weak current line need to be
routed separately.
A minimum distance of 10 cm has to be
maintained from the heavy current lines.
The power supply to the Bus- guidance
board passes through the VT 12 network
transformer.
The VT 12 transformer has to be connected
by means of a separate 10 A safety switch.
The installation of electronic appliances
should only be performed by a specialised
electrician.
Caution:
When installation of the CTC-Duo-PLUS Bus
system is effected on an existing line network
(e.g. installation of door bells), it will have to
ensured that the lines are free from any
foreign voltage.
Line resistance should not exceed 600 Ohm.
The theoretic line length values resulting for
a mean copper cable thickness of 0,6 mm
exceed 4,5 km.
A BTU Bus entry selector, a BSP 16
central unit and a VT 12 network
transformer will be required for each
additional substation.
Programming and operation
Programming is basically taking place through the transposition of
the jumpers at the HT 522 inphone.
The BSP 16 Bus central unit offers the ability to change the
duration of response of the door opening switch from 3 to 5
seconds.
(1) Set in operation in 5 seconds.
The TLR 550M Bus loudspeaker module is installed within the
keypad box (2).
Bus line (3) is installed at terminals a+b.
The entry substations are installed at the BR terminals (4)
Accordingly to the needs, where the busy indication may be guided
over the terminal (5) to the exterior (optional).
The contacts of the door opening and additional function switches
should not be connected to the 230V network voltage
Maximum connection output 30 Watt or 60 VA at 12 V=/~.
As an option, you may install the MDK 12-key keypad
(connection 10).
The only thing remaining is to program the HT 522 Bus
inphones according to the binary code, through the
installation of the jumpers.
Following the call from the doorstation, the call receiver has
approximately 30 seconds to lift the receiver, otherwise the call
will have to be repeated.
Communication is interrupted automatically after 45 seconds
approximately.
