We sell a product that does exactly this.  Its marketed as a duress call for
the elderly, but all it does is trigger a relay on a receiver.  You have to
be withing about 70 feet of the receiver so you could not mount the receiver
in you house, but you could mount it on the chair and then trigger something
else (a cellular phone?)
