Figure 2.9. Connecting the Accord
XP
C to the PSTN
It is strongly recommended that the Accord xpC panel is the only device on the line.
If another device is to be connected to the line, connect PHONE terminals on the Accord
xpC PCB to the terminals 2 and 5 on the ADT BT Box.
The ADT socket is the customer master, which supplies all other telephone points in the
premises. All sockets must have the same polarity.
Using cable suitable for connection to 2.8 mm diameter screw terminals, strip back
approximately 20 mm of the outer sheath and then remove approximately 4 mm of the
insulation from the wires to be connected to the Accord xpC.
Connect terminals 2 and 5 on the BT Master socket across the A and B terminals (TB5)
on the Accord xpC, refer to Figure 2.9.
Example: The control panel enclosure must not be opened before isolating the mains
supply. Illumination of the green power LED indicates the presence of a.c.
mains supply. The cover of the Accord xpC enclosure must be replaced
whenever any connection to the BT master socket is completed to prevent
exposure to potentially lethal voltages from the PSTN.
If using the older type of BT socket (not NTE5), then connections should be made as
shown in Figure 2.10.
The Telecommunications Network Voltage (TNV) port (terminals A and B on TB5) is
connected to the BT master socket via the terminal block in the back of the ADT socket.
Note: Connection to the older type of master socket cannot be performed by an ADT
engineer and must be made by the network operator. A line jack and captive
locking bar are used to prevent the customer from unplugging the alarm from
the telephone.
