3-30V AC/DC ST A TUS IN 4 I NFRARED MAIN S YSTEM UNIT MSU250 Parts Guide 1. 12VDC Jack – Provides 12 volt DC power to MSU via a regulated power supply . 2. IR Flasher Outputs – 3.5mm jacks provide output for either single or dual (MF1, MF1VF , MF2, MF2VF) low-level flashers.
Installation Considerations Placement of the MSU250 Place the MSU250 conveniently close to the equipment it will be controlling. Generally , the unit is placed in a concealed location because its controls and indicators are only used dur- ing installation.
Wiring From every IR Sensor location you must “home-run” a category 5 cable back to the MSU250. Home run means that an individual cable is connected between each IR Sensor and the MSU250 (Figure 4). 6 I NFRARED MAIN S YSTEM UNIT “TECH TIP” Wire size is expressed by it’ s A WG (American Wire Gauge) num- ber .
IntelliPad Wiring 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 either the sensor back to the MSU250.
3-30V AC/DC STATUS IN Installation Before you begin, make sure that the sensor/keypad cables, the flasher cables and the 12VDC power supply cable will all reach the proposed location of the MSU250. Mark the cables with labels describing where the cable originates (rather than which terminal on the MSU250 it should connect).
9 I NFRARED MAIN S YSTEM UNIT STEP DESCRIPTION 1. Connect and test the pow er supply . If it tests OK, unp lu g the connector from the power socket and proceed. A) Plug the supplied 12VDC power supply into an unswitched 120 volt AC outlet, 50-60 HZ . B) Plug the connector into the socket marked “Power” on the MSU250.
10 I NFRARED MAIN S YSTEM UNIT STEP DESCRIPTION BE SURE TO OBSERVE PROPER POLARITY WHEN EXTENDING THE FLASHER WIRE. The wire lead marked with a gray stripe is positive ( + ) ; the unmarked lead is negative (- ) . 3. T est for shorts and interference. A) Reconnect the power supply .
11 I NFRARED MAIN S YSTEM UNIT T esting the IR Extender System T est your IR Extender system by following the 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 MAIN S YSTEM UNIT 12 V olt T rigger Output The Niles MSU250 provides a 12VDC output that can be trig- gered one of two ways: 1. The presence of status voltage on the 12VDC status input jack. 2. Discrete infrared on and off commands. The discrete on and off commands are available for download at: www .
13 I NFRARED MAIN S YSTEM UNIT Power Status — Introduction T o properly wire an IntelliPad to the MSU250, refer to Figure 5. By providing 3-30 volt AC/DC to the status input jack of your MSU250 you can send a status signal to sensors or an IntelliPad without running any additional wiring.
14 I NFRARED MAIN S YSTEM UNIT 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 polari- ty . The tip of the plug should be positive (+) and the sleeve negative (-).

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. T roubleshooting Guidelines There are three basic problems which prevent proper opera- tion.
17 I NFRARED MAIN S YSTEM UNIT 2. Optical or Electromagnetic Interference Direct sunlight, reflections, neon signs and other sources of infrared light or television sets, light dimming controls and other sources of electromagnetic fields can induce noise and interference into your IR extender system.
18 I NFRARED MAIN S YSTEM UNIT 3. Optical Feedback Loop If you have an IR sensor in the same room as a flasher , and you have some low-level noise or interference, an optical feedback loop can occur which will interfere with proper operation. Symptoms can include: poor range, intermittent operation or no operation.
19 I NFRARED MAIN S YSTEM UNIT Specifications IR System Compatible with virtually all brands of remotes using carrier frequencies between 26 and 1 05kHz. W iring Requir ements Individual home-runs of category 5 cable from each sensor/keypad. Unit Dimensions 5-11/16” wide x 1-1/4” high x 2” deep.
