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 the sensor back to the MSU140. T o prevent data feedback an IN4003 Blocking Diode is inserted on the data (IR) line between ...
