Re: Problem With ADT System - Need Advice

No not in parallel...took risky imo.

I put them in slightly overlapping areas where a burglar would have to cross
through both within a certain amount of time, then use the software
cross-zone feature of the panels I install to set a crosszone time 5sec
10sec whatever seems right. If one zone trips it sends kinda fault, if both
trip within the cross zone time it sends a real alarm. I can even crosszone
a device with itself.
