Fitting a Plug-by Communicator (all models)

The control unit can be fitted with a communicator or speech dialler (for

example, the Scantronic 8400, 8440, 660 or RedCare STU). To fit a

communicator, follow the instructions below.

Caution: Follow the instructions in the order shown, or you may damage

the control unit and/or communicator.

1. Disconnect mains and battery power from the control unit and remove

the case lid, if the system has already been installed.

2. On the 9751:

a) Detach the main PCB from the support pillars in the control unit

case, and lift the PCB carefully to the left.

b) Fit the communicator between the PCB support pillars, making sure

that the main PCB can fit back into position (see Figure 31).

3. Make any necessary connections from the communicator to the

Communication Wiring Harness. Figure 32 shows the outputs available

on the free ends of the Communication Wiring Harness. The default is a

positive voltage when the output is inactive but this can be inverted if

required using Command 159 (see page 109).
