IRP6+
Six remotely located IR Sensors are connected to an IRP6+. One IR Flasher, connected to the IRP6+, is transmitting an IR command
to the Receiver’s IR sensor. The IRP6+ enables you to connect up to eight Niles IRC-1 Flooding Flashers and up to sixteen Niles
IRC-2 MicroFlashers. The IRP-6+ is powered by plugging into an unswitched AC outlet.

Proper Power Supply
CONVERTING A LOW VOLTAGE CONTROL OUTPUT TO 12V DC
You must connect a Niles 12v DC
wall adapter (Niles XF00019) into
the switched AC power outlet of the
preamp/receiver in your system.
Any 12v DC power supply with a
minimum of 100mA current capaci-
ty can be substituted.
Many components, particularly surround processors and digital preampli-
fiers, provide a low voltage whenever the component is “on” rather than
in “standby”. For the IRP6+ to correctly broadcast power status you must
install an optional Niles OTI-512 Opto-Isolated trigger interface. The OTI-
512 will convert 3-30 volts AC or DC to 12v DC.
