Looking to build out my first system for a new home. I’m going to use a Qolsys IQ 4 Panel and looking at DCS PG9984P motion sensors for front and back doors areas.
Most of DSC product lines have 2-3 product numbers for a given product.
Example:
PGx984P
(PG9984P; PG4984P; PG8984P)
Typically it seems there’s a 4, 8, and 9.
I’m not really sure what the differences are between these version or how to find out. It seems possible the 9x are UL listed and the others aren’t?
