Niles Audio MSU250 manual Intellipad Wiring, SENSOR/KEYPAD Cable

INSTALLATION CONSIDERATIONS (CONTINUED)

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.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 diode, faces the IntelliPad. (Figure 5). Note that status wire is connected to IntelliPad’s status

(+) connector.

SENSOR/KEYPAD CABLE

The MSU250 connects to IR sensors and the IntelliPad with CAT-5 cable, with a maximum cable

run of 500’ (152.4m). Flasher cable Niles infrared flashers come supplied with a 10’ (3m) 2-conduc- tor 22 gauge cable. Should you need to extend it, use a 16 gauge 2-conductor cable (“zip-cord”). Shielding is not necessary for a flasher. Flasher wires can be extended up to 200’ (61m).
