  I got called to replace 3  Aritech PIR on a Radx 8112. Both as old
as my Grandfather. I need somebody to clue me in on the wiring for
this. it has a terminal strip 1.Black 2. Red 3. Red 4. Green  6. White
and Red wire both in postion 6. 5,7,8 have no wires going to them.
Obviously 1/2 Should be power 3/4 guess would be the loop from the
popit 6. With the red wire and white wire is lost me. Maybe a tamper?
Can somebody please clue me in? Thanks
