There should only be about 75' of cable between the 2.  I will try
shorting the sensor wires.
Can you please tell me what voltage levels should be present on both
conditions.  One more
interesting bit of info on this is that the sensor wires can only
connect one way otherwise the
system does not come up if I swap the HI and LO.
