12. Plug the power cords from 6 of the Source Components into the Current Sensors of the GCM1
GATEKEEP-IR modules. In turn, plug the Current Sensor units into unswitched 120 VAC outlets. Also,
plug the two SAT receivers into 120 VAC unswitched AC outlets.
In this particular setup, the SAT
receivers use the GVM1 video sensing modules rather than current sensing. Refer to the GATEKEEP-
IR Installation Instructions for all GATEKEEP-IR programming procedures.
13. Set all power switches on the PA640's to the OFF MANUAL (REMOTE ON/OFF) position.
14. Plug all remaining power cords into unswitched 120V AC outlets.
CAUTION: When configuring your own particular system, be sure to take into consideration the power
demands of all keypads, IR receivers, etc. See POWER SUPPLY CONSIDERATIONS on the following
page. When you have done this and completed all connections, the ZPR68-10 system would then be ready
for the Setup and Operating Procedures.
POWER SUPPLY CONSIDERATIONS
The total current available from the
+12V
, the
STATUS
and
CO
(control out) terminals on the ZPR68-10
to power keypads, infrared receivers, switching devices, etc., is
1.8 A
. In addition, each of the zone
STATUS
terminals and the
CO
terminal have a current limit of
90 mA
each max. These currents are enough to power
all but the most unusual installations.
However, if you have a system where the total current demand
does exceed 1.8 A, then an external power supply(s) must be used to power the extra devices to
prevent overheating and shutdown of the ZPR68-10.
The following table shows the current required by Xantech devices typically used with the ZPR68-10 in
zoned-controlled multi-room systems:

Procedure
Add up the current demands for the devices used in the system. If the total current exceeds
1.8 A
, it is then
necessary to use a 782-00 power supply to separately power the
V
or
+12V
terminals of the additional
devices that cause the over-current condition. See typical connection diagram,
Fig. 7
.
Note:
The STATUS or CI (Control Inputs) of the devices must remain connected to the respective zone
STATUS
and common
CO
terminals on the ZPR68-10, where used. Also, if you exceed
90 mA
on any of
these terminals, use a Xantech
CC12
Remote Relay Module to reduce the current demand. Refer to the
CC12 Installation Instructions, Fig. 6, for details.
