Thanks.

That won't work because I already stated the model # of the PIR's. The
contact is NO.  Which BTW Ademco labeled the contacts wrong... they
think they do installers a favor by backwards labeling.  NO means the
contact is open in a shelf-state (like every relay is labeled) -

Ademco has it bass-asswards.  When I see any component I adhere to
shelf-state meaning no power applied.  So a motion detector should
land on the NO contacts of a normal "closed loop circuit", common in
our industry.  But Ademco, in their infinite wisdom,  decided to
switch the label - probably because most alarm techs have not
graduated the 8th grade.. huh?

That is a bug.
