connections to a Xantech connecting block,
power supply and emitters as shown in the
following illustration of a typical basic system:
While it is possible to make wired connections
without the connecting block, it is not recom-
mended. The connecting block reduces instal-
lation time, helps to eliminate errors, allows
easy troubleshooting and permits easy system
upgrades later, if needed.
Input connections must be made as illustrated.
To extend the Emitter wires to a more distant
location, you may splice in 2-conductor wire, in the wire gauges mentioned before, as needed.
The 780-10 may be connected to any of the Xantech Connecting Blocks, Controllers, Interface modules,
etc., that have +12 VDC, INPUT and GND terminals, such as the CB12, 789-44, 791-44, 795-20, 796-20,
794-00, etc. 780-10's may be connected in parallel to these terminals in any combination with other Xantech
3-conductor IR receivers or keypads (12 IR receivers max).
A more advanced system, using 780-10's and a variety of other Xantech IR receivers connected to a 791-
44 Amplified Connecting Block, is shown in
Fig.3
below:
Affix the Mini-Emitters, such as the 282, 284,
283 and 286 series, to the IR sensor win-
dows of the controlled equipment in accord
with the instructions that come with them.
Phantom Power Connections
Some existing installations may have only 2
wires (such as coax) going to a remote room.
The 780-10, when used with a 792-10 Power
Module, may be connected for 2-wire phan-
tom power operation as in
Fig. 4
.
Additional 780's may be wired in parallel at
the
IN
and
GND
terminals of the 792-10, up
to a maximum of three. More than this may
cause unreliable results.
CAUTION:
With any of these systems, be
sure the 781 power supply is plugged into an un-switched AC outlet. This maintains the IR system in
"standby" operation so that power-on commands can be sent to the controlled equipment.
