OPERATION (CONTINUED)
connected to one of your sensor wires will display the power status of your system.
POWER STATUS — INSTALLATION CONSIDERATIONS PROPER POWER SUPPLY
If status is being supplied from a switched outlet you must connect a Niles 12VDC wall adapter (Niles FG00665) into the switched AC power outlet of the preamp/receiver in your system. Any 12VDC power supply with a minimum of 100mA current capacity can be substituted.
Extending the Cable
If you must extend the cable from the wall adapter to the MSU250’s status input jack be sure to maintain correct polarity. The tip of the plug should be positive (+) and the sleeve negative
Checking the Power Supply
It is possible to check the status power supply itself and any connections that were made to extend the cable by inserting the status plug into the Power jack on the MSU250. If the Power LED lights the status power supply and connections are ok. If the Power LED does not light check all connections and replace the power supply if necessary. For more details on incorporating the IntelliPad please refer to the IntelliPad’s users manual.
System Expansion
System expansion is easily achieved (Figure 9) through the use of an IRH610 infrared sensor expansion hub. Please see your authorized Niles dealer or refer to the IRH610 manual for details.
