The issue is nomenclature. 9-1-1 is the WRONG term to put on the device. First of all, 9-1-1 is not universal - it's 9-9-9 or 0-0-0 in other countries.

Secondly, 911 is a fast-response, local service. A simpler thing is a red button and that's it - no "9-1-1" response here.

Finally, there should be a cost for each 9-1-1 press. I'd say $200 is about right. If it's a real emergency, that's not a lot of money and anyone would press the button for help.
