Wiring From every IR Sensor location you must “home-run” a category 5 cable back to the MSU140. Home run meansthat an individual cable is connected between each IRSensor and the MSU140. See 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 expressed by it’s AWG (America...

Intellipad Wiring When you are placing both a Intellipad and a sensor (ortwo keypads) in one room you may “daisy-chain” using asingle cable. A cable is run between the keypad and thesensor and a single cable is run from the sensor back to theMSU140. To prevent data feedback an IN4003 BlockingD i o d...
