input and ground) and the 4K7 resistor is used as the normal end-
of-line resistor.
The colour codes for the 12K and 4K7 resistors are as seen in

4. Connecting the Telephone Communicator

Refer to Figure 1.
The integral communicator has built in lightning protection to
protect it from lightning induced transients. For optimum
protection connect a low impedance earth to the communicator. A
poor earth will be ineffective and may result in damage to the
communicator and alarm panel.
Always connect the telephone communicator in the line seizure
mode. Never in parallel with the telephone i.e. connect the
telephone receiver to the communicator terminals marked "phone"
and the incoming line to the terminals marked "line".

5. Programmable Outputs

A relay board must be used when any device requiring a high current is
connected to a programmable output. The current sink and source
capability is the same for outputs 1, 2 and 3. The output circuitry
consists of a 12 volt source with a 56Ω series resistor. Current sink is
via a 1000Ω resistor to negative. The output circuitry is provided in
Figure 4 overleaf.
There is also an expansion board attached to the keypad bus which
provides for an additional two programmable outputs which function as
per outputs 1 - 3. See the connection diagram in Section 2 for further
details. See also Section 6: Expansion Board.
