GE also has a product called Mobility that's DESIGNED to push alarms and messages to phones and tablets via wifi or cell network. You can actually download the app for it in the App Store and play around with it some. Really nice interface/GUI as well. It also has the ability to prioritize, assign, and push alarms to the closest tech, so that your staff doesn't all get flooded with the same stuff.
I've seen it in use at a Semiconductor plant, a military base, a refinery, and a water/wastewater plant - works like a charm. I can get more info on the Water application if you want...PM me and I'll e-mail you a bunch of documentation I found on it.
