Safety Notice
Figure 34 identifies connectors for Safety
Extra-Low Voltage (SELV) and
Telecommunications Network Voltage (TNV)
circuits on the control unit's main PCB.
These terms are used in accordance with
the definitions in Safety Standard EN60
950.
The Installer must ensure that TNV
terminals are connected
only to other
circuits designated as TNV circuits (for
example, the PTSN) and that SELV
terminals are connected
only to other
circuits designated as SELV circuits. Strict
adherence to the installation instructions
will ensure that the equipment continues to
comply with the safety regulations to which
it was approved.
TNV - Telephone line connector.
SELV
– All other connectors.

Connecting the Telephone Line
Connecting the telephone line directly to
the terminals on the internal communicator,
or indirectly through other apparatus, can
produce hazardous conditions on the
telephone network. Always seek advice
from a competent telephone engineer if in
any doubt about connecting to these
terminals.
Example – connecting a line in the UK:
The internal communicator must be
connected to the telephone network by:
a) If the wiring is owned by British
Telecom:
British Telecom.
b) If the wiring is not owned by British
Telecom, one of:
(i) British Telecom.
(ii) The authorised maintainer.
(iii) A professional Installer, after 14
days written notice to the authorised
maintainer.
To connect the telephone line (see Figure
35):
(i) Using a two-core telephone cable,
strip off 5mm and feed the cable
through one of the entries (marked
“10” in Fig. 2) in the rear of the
control unit. Connect the two cores
to terminals A and B on the main
PCB.
(ii) Connect the other end of the two
cores to the corresponding terminals
on the BT master box.

Fit ADSL Filter
If the telephone line is being shared by a
broadband service then you should fit a
broadband filter to the line. Cooper Security
provide the ADSL01 filter that plugs onto
pins provided for the purpose on the main
circuit board of the control unit (see 21 on
Figure 3). Figure 36 shows how to fit the
filter.
