4. Wire the Sensor 
 
Note: Observe proper polarity. 
For new polling loop installations, 
always use shielded twisted pair 
wiring. In many cases, existing non-
twisted pair wiring may be used, but it 
is more susceptible to interference 
from other sources, and may be 
problematic in installations with long 
wire runs or in high noise 
environments. 
Shielded wiring must be used.
