Hi comforter,
You could possibly set up a wireless personal alarm.
This one can be set up to have the message paged to you by the sound of it. When I think about it all the aged care facilities here have emergency button that goes directly to the main office and not to emergency services. That could probably be worked into your home situation. It's difficult to tell if the button on this one is large or small.

There's one called a Bluetooth panic button "Engaget" which seems awfully complicated to me compared with the school one above. I'm sure there are other devices. If I find anything I'll post it.

I'd suggest asking on the ALS forum here at NeuroTalk. http://neurotalk.psychcentral.com/forumdisplay.php?f=6
Also, a knowledgeable OT or Assistive Technology Practitioner (ATP) should know of something.

can't find anything specific on this one, but it's a great general site.
