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
"Off" 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.
