A cable is run between the keypad and the sensor and a single cable is run from the sensor back to the MSU140. To prevent data feedback an IN4003 Blocking Diode is inserted on the data (IR) line between the Intellipad and the sensor. The cathode, or blocking side of the dio

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. Built into the MSU140 is a Niles status signal generator. When the MSU140 sees 3-30V AC/DC at the status jack it broad- casts a status signal over your existing I

Move the sensor or the sensor cable away from the EMI source or move the source of the EMI away from the sensor or the cable. 2. Connect the Sensor’s GND terminal to true earth ground (if this isn’t feasible use the main system unit’s GND terminal). 3.– Optical Feedback Loop If you have an IR sensor in the same room as a flasher, and you have some low-l
