Safety Notice

Figure 28 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

29):

(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.

Communicator

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 5 on

Figure 2). Figure 30 shows how to fit the

filter.
