Connecting the AC Mains Transformer

This product uses the 1361 Transformer in 110 VAC
markets. If you are using powerline carrier devices, use
the 4300 Transformer. In Australia, use the XF10 and
in Europe, use the XM10E in addition to the normal
16.5VAC/40VA output transformer.

Wiring the 1361 Transformer
Wire a 1361 110VAC Transformer (not supplied) to
terminals 1 and 2 on the control panel as shown in
Figure 3-37. In 220VAC regions, use a 16.5VAC/40VA
output transformer.
Wiring the 4300/XF10 Transformers
Wire the 4300 Transformer as follows:
1.
Connect terminals 1 and 3 (AC) and terminal 2
(Ground) of the 4300 transformer interface to
control panel terminals 1, 2, and 30, respectively,
see Figure 3-38.
2.
Run a 6-conductor cable between the 4300 and the
panel. Splice this cable to a 4142TR cable as shown
below. Note that the white and yellow wires of the
4142TR must be spliced together.

Earth Ground Connections

In order for the lightning transient protective devices in
this product to be effective, the designated earth ground
terminal (terminal 30), must be terminated in a good
earth ground. We recommend using 1.3mm diametre
copper wire run at a maximum length of 7.5m. The
following are examples of good earth grounds available
at most installations:

Calculating the Battery Size Needed

In the event of an AC power loss, the Control panel will
still operate for a period of time (time period varies
depending on size of battery used) because the control
has a back-up, rechargeable (sealed) lead acid battery.
ADEMCO 467 (12V, 4AH) and ADEMCO 712BNP 12V,
7AH batteries are recommended.

Section 3 – Installing the Control
In Australia, use the XF10 and in Europe, use the
XM10E in addition to the normal 16.5VAC/40VA output
transformer. See Figure 3-39.
X-10 Powerline Carrier devices are either plugged into
standard AC outlets or wired into the AC electrical
system by a licensed electrician, depending on the type
of device used. They respond to "on" and "off"
commands sent from the panel, through the
4300/XF10/XM10E, to the receiving devices.

Metal Cold Water Pipe: Use a non-corrosive
metal strap (copper is recommended) firmly
secured to the pipe to which the ground lead is
electrically connected and secured.
AC Power Outlet Ground: Available from 3-
prong power outlets only. To test the integrity of
the ground terminal, use a three-wire circuit tester
with neon lamp indicators.
The standby battery is automatically tested every 4
minutes for 13 seconds (or every 50 seconds for 1.5
seconds, as a function of program selection) and every
24 hours for 10 minutes, beginning 24 hours after
exiting programming mode.
Use the following worksheets to calculate the total
current drain on the control panel.
