Installation Considerations Placement of the MSU140 Place the MSU140 conveniently close to the equipment it will be controlling. Generally , the unit is placed in a con- cealed location because its controls and indicators are only used during installation.
W iring From every IR Sensor location you must “home-run” a category 5 cable back to the MSU140. Home run means that an individual cable is connected between each IR Sensor and the MSU140. See Figure 4. 6 I NFRARED M AIN S YS TEM U NIT “TECH TIP” W ire size is expressed by i t’ s A WG (American W ire Gauge) number .
Intellipad W iring When you are placing both a Intellipad and a sensor (or two keypads) in one room you may “daisy-chain” using a single cable. A cable is run between the keypad and the sensor and a single cable is run from the sensor back to the MSU140.
1234 POWER +12V DC 3-30V AC/DC STA TUS IN FLASHER OUTPUTS MSU140 IR MAIN SYSTEM UNIT INPUT 1 Sensor/Keypad Cable The MSU140 connects to IR sensors and the Intellipad with category 5 cable, with a maximum cable run of 500'. Flasher Cable Niles infrared flashers come supplied with a 10 foot 2-con- ductor 22 gauge cable.
9 I NFRARED M AIN S YS TEM U NIT STEP DESCRIPTION 1. Connect and test the power supply . If it tests OK, unplug the connector from the power socket and proceed. A) Plug the supplied 12vDC power supply into an unswitched 120V AC outlet, 50-60 HZ . B) Plug the connector into the socket marked “Power” on the MSU140.
STEP DESCRIPTION 10 I NFRARED M AIN S YS TEM U NIT 123 4 FLASHER OUTPUTS BE SURE TO OBSER VE PROPER POLARITY WHEN EXTENDING THE FLASHER WIRE. The wire lead marked with a gray stripe is positive ( + ) ; the unmarked lead is nega- tive (- ) . 3. T est for shorts and interference.
11 I NFRARED M AIN S YS TEM U NIT T esting the IR Extender System T est your IR Extender system by following these three principal guidelines: 1. All components can be operated. T est all of your remote controls for all of your equipment. 2. Operation is consistent.
12 I NFRARED M AIN S YS TEM U NIT Power Status — Introduction T o properly wire an Intellipad to the MSU140, refer to Figure 5. By providing 3-30V AC/DC to the status input jack of your MSU140 you can send a status signal to sensors or an IntelliPad without running any additional wiring.
13 I NFRARED M AIN S YS TEM U NIT 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 FG01035) into the switched AC power outlet of the preamp/receiver in your system.

15 I NFRARED M AIN S YS TEM U NIT T roubleshooting Guidelines There are three basic problems which prevent proper oper- ation. In the order of probability the problems are: 1.– Bad Connections or W iring If the connections or wiring are wrong, loose, shorted or open the system will not operate properly .
16 I NFRARED M AIN S YS TEM U NIT Solution: T o eliminate EMI try the following methods: 1. Move the sensor or the sensor cable away from the EMI source or move the sour ce of the EMI away from the sensor or the cable.
17 Specifications IR System Compatible with virtually all brands of remotes using carrier frequencies between 26 and 1 05kHz. W iring Requirements Individual home-runs of category 5 cable from each sensor/keypad. Unit Dimensions 4-3/4” wide x 1-1/4” high x 2” deep Power Requirements 12VDC power supply (included).
