The examples shown below illustrate a PAD device's dip switch settings: the 1st example shows a device not addressed where all
dip switch settings are in the default "O" position, the 2nd illustrates an addressed PAD device via the dip switch settings.

Before connecting a device to the SLC loop, take the following precautions to prevent potential damage to the SLC or device.
• Power to the SLC is removed.
• Field wiring on module is correctly installed.
• Field wiring has no open or short circuits.

The wiring diagram shown below illustrates how to wire a PAD200-DUCT duct detector.
Figure 3. Example of Wiring a PAD200-DUCT Duct Detector
Notes:
• SLC wiring style supports the Class A, Class X and Class B.
• SLC loop wiring is power limited.
• SLC loop wiring is supervised.
• Wiring for terminals are supervised.
• All wiring is between #12 (max.) and #22 (min.).
• Wire Preparation – Strip all wires 1/4 inch from their edges as shown here:
– Stripping too much insulation may cause a ground fault.
– Stripping too little may cause a poor connection and subsequently an open circuit.
