ZNR Help

[Jerry D]

Still working on transients turning on my motion light. I found a "ZNR" in my old Digi-Tech catalog which looks promising. A search on Google reveiled that it may/should? be used with an r/c across it but the circuit diagram doesn't show up on my recently downloaded Adobe.
Anybody have any idea as to what values for the R/C circuit I would need for 120vac? Do you guys think the ZNR would work for my problem?

Thanks, Jerry.
