Power Status — Installation Considerations
Proper Power Supply
You may connect a Niles 12VDC wall adapter (Niles FG00665)
into the switched AC power outlet of the preamp/receiver in
your system. Any 3-30V AC/DC power supply with a minimum
of 20mA current capacity can be substituted.
Extending the Cable
If you must extend the cable from the wall adapter to the
MSU480’s status input jack be sure to maintain correct polarity.
The tip of the plug should be positive (+) and the sleeve nega-
tive (-). Any 16 gauge 2-conductor cable can be used to extend
the power status cable up to 200 feet.
Troubleshooting Guidelines
There are three basic problems which prevent proper opera-
tion. In the order of probability the problems are:
1.Bad Connections or Wiring
If the connections or wiring are wrong, loose, shorted or open
the system will not operate properly. The symptoms could
include: Power LED flickers or is off, IR Test LED is continuously
flickering or on without any remote control use, intermittent
operation or no operation.
Test your power supply connections.
Test your Sensor connections.
Test your Flasher connections.
Tests your cable for shorts and opens.
