I would like to see buildings take over this monitoring like fire and sway sensors and provide the group with a dry contact. There is a lot of talk in CA about early warning sensors from USGS that would provide a few seconds warning. I feel like a EQ sensor for the entire buildings systems would be a more robust system than what the elevator industry currently uses, preventing false trips and battery power failures.
On the other hand we sell a lot of UPS power packs for EQ boxes after first group EQ trip due to dead batteries.
