Installation Considerations Placement of the MSU250Place the MSU250 conveniently close to the equipment it willbe controlling. Generally, the unit is placed in a concealedlocation because its controls and indicators are only used dur-ing installation. Placement possibilities include: 1) Table-top (o...

Page 7 - IMPORTANT – AVOIDING INTERFERENCE; Remotely Located

Wiring From ever y IR Sensor location you must “home-run” a category 5 cable back to the MSU250. Home run means thatan individual cable is connected between each IR Sensor andthe MSU250 (Figure 4). 6 I N F R A R E D M A I N S Y S T E M U N I T “TECH TIP” Wire size is expressedby it’s AWG (American W...
