150 Hardwired Zones - What Security Panel Mfg?

I have a commercial building that will have operable windows spread across 3 floors and 100,000 sq feet. They would like to know when they are left open via email/SMS. What security panel mfg has the ability to expand out that far, I have seen 128 as the max.

I was thinking that each IDF (network closet) would house the zone expansion module.
