Wire must be 12 AWG (3.309 mm
2
) to 18 AWG (0.8231 mm
2
), non-power limited. Wiring must
test free of all grounds. Wire as follows:
1. Route wire from the CLK B, CMD B, SIG B, REF B and SHLD outputs of the XALIC card
to the appropriate inputs on a XA Loop device.
2. Route wire from the first XA Loop device to the next one. Repeat for each appliance.
3. Route wire from the last XA Loop device to the CLK A, CMD A, SIG A, REF A and SHLD
inputs on TB3 of the XALIC.
Note: Class A wiring is required if any of the XA loop devices are intended to serve as
initiating devices that initiate a preaction/deluge function.
