1. Main System Unit Power Supply Check that the red power light on the main sys tem unit is lit the in line power supply should be plugged into an active AC wall outlet and supplying 12V DC TECH TIP N Wire size is expressed by its WL AWG American Wire Gauge number The lower the number the larger the wire i e twelve AWG is physically larger than fourteen AWG Optical IR Feedback Loop If there is an IR sensor and an IR flasher located within the same room an optical IR feedback loop can occur This occurs when the IR output from a flasher unintentionally reaches an IR sen sor located within the same room The IR com mands are eventually forwarded back to the IR flasher and the whole process endlessly repeats itself This effect is similar to acoustical feedback the howling or whistling sound heard in a P A system when the microphone is placed too close to the speaker The optical IR feedback loop can be eliminated by one of the two following methods 1 Relocating the sensor in order to break the IR feedback loop 2 Replace the IRB1 with a MF Series MicroFlasher MF1 MF1VF MF2 MF2VF for each component controlled by the problem causing flasher If problems persist refer to the user s manual for the main system unit or contact your local Niles dealer If further assistance is required contact Niles Technical Support at 1 800 289 4434 SPECIFICATIONS IR System Compatible wi2.

4. bounce infrared light off of smooth reflective surfaces particularly white surfaces If a suit able surface exists like the back of a cabinet door or a white wall within a few feet try to place the IRB1 so that its reflected output reach es the sensor windows of the components See Figure 4 If some of the components are still not getting adequate signal mount a Niles MF series MicroFlasher on the sensor window of each of the problematic components Sometimes it is desirable to mount the IRB1 so that it directly faces the equipment from across 3 a room In this type of situation the IRB1 has an effective operational range of 18 to 30 depending on brand and model of audio video equipment INSTALLATION amp OPERATION Route the connecting wire to the main system unit Most Niles IR main system units feature specific flasher outputs that are selectable between low and high output Insert the 3 5mm plug of the IRB1into one of these selectable FLASHER OUTPUTS jacks on the MSU Slide the corresponding switch on the MSU to the high position See Figure 1 3 30V AC DC NILES U250 SYSTEM UNIT FIGURE 1 Connecting the IRB1 to the main system unit s flasher outputs Increasing the Wire Length If the connecting wire is too short to reach the main system unit a new length of heavier gauge wire should be spliced onto a six inch length of the original wire For distances between ten and twenty f

INSTALLATION amp OPERATION GUIDE IDR IRDB1 High Ouput Infrared Flasher NILESe BLENDING HIGH FIDELITY AND ARCHITECTURE INTRODUCTION The IRB1 is a small cabinet mount high output infrared flasher The IRB1 is just one part of the three building blocks necessary to complete a Niles IR extender system e IR Main System Unit Models MSU140 MSU250 MSU480 and MSU440Z e IR Sensors Keypads Models WS100 TS100 MS100 MS200 CS100 MVC100IR and the IntelliPad e IR Flashers Models MF1 MF1VF MF2 MF2VF and the IRB1 An IR sensor expansion hub Model IRH610 is available to provide additional sensor inputs to your system When an IR remote sensor receives a command from a hand held remote control it sends a cor responding electronic signal through a wire to the main system unit Here the main system unit cleans and amplifies the electronic signal Finally the main system unit outputs the signal to the IR flasher which relays the infrared com mand to the audio video component you wish to control The IRB1 relays the infrared command using flashes of infrared light in a powerful flood ing pattern from its two infrared LEDs The out put is extraordinarily accurate over a wide bandwidth This allows the IRB1 to control most makes and models of IR controlled audio video components 1 The IRB1 is compatible with all Niles infrared extenders systems IntelliControl and MultiZone recivers
