Step 6. Fit a Plug-By
Communicator
The control unit can be connected to a
separate communicator or speech dialler
(for example, the Scantronic 8400, 8440,
660 or RedCare STU). Figure 20 shows the
connections provided by the
communications wiring harness.

Note: Comms O/P4 will be active when the
system is unset. This is normal.
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. Make any necessary connections from
the communicator to the communication
wiring harness. The default is a 12V
positive voltage when the output is
inactive.
Refer to the next section if you are
using a dual-path communicator.
3. Plug the Communication Wiring Harness
onto the communications connector on
the main PCB.
If the system has already been installed:
4. Re-connect the battery.
5. Fit the case lid.
6. Apply mains power.
7. Test communicator operation.
Line Monitoring for a Dual-Path
Communicator
If a standalone dual-path (landline and
mobile) communication device, such as a
RedCARE STU, is connected to the plug-by
connector, you need to do the following to
obtain correct line fault reporting (this is
not necessary if you are using a plug-on
module):
1. Wire a panel output programmed as
type "ATS Test" to the ATS Test input of
the communicator.
2. Wire the Line Fault output of the
communicator to the Line Fault input of
the plug-by connector. The
communicator must provide +12Vdc to
indicate a line fault (for example, if the
Line Fault output at the communicator
uses a relay, connect the common
terminal of the relay to +12Vdc and the
normally-open terminal to the Line Fault
input of the plug-by connector).
The panel will generate an "ATE L.F. Single"
alert if only one of the networks is not
available, or "ATE L.F. All" if both networks
are not available.
Step 7. Fit and Connect
Battery
Fit a 7Ah Lead Acid battery into the battery
compartment in the bottom of the control
unit, see Figure 21.
Make sure that you secure the battery to
the case with the strap provided. Connect
the battery leads, red to the positive, black
to the negative terminals of the battery.
