*Combinations shown represent maximum loads that may be powered from one
transmitter without remote power.
NOTE: Only use single catalytic or XIR sensor configuration with 7 W power supply.
If at least one sensor is remote with signal boost or has remote power, any combination is available.
Recommended power supply selection is for operation not to exceed 65% of capacity.
See Installation Outline Drawings for details.
