I don't know the answer to your question but I thought I would share something that I concocted when my Dad was sick.

We wanted Dad to be able to let us know if he needed help but we also wanted to go about our chores in the house. I looked everywhere for some type of calling device to use inside our home. I couldn't find anything but I came up with this.

I bought a wireless, desktop doorbell system. I think it was less than $30. I took the push button part of the doorbell system and glued it to an ID lariat -- the kind that has a clip on it and you can pull it out. In other words, instead of installing it on the outside of our house, we clipped it to his shirt pocket and he could pull out the string and push the button when he needed us. We laid the sound part of the doorbell system at the edge of the open staircase to our lower level. Our condo is over 3,000 square feet and you could hear the bell throughout the entire house, the deck and the lower patio. [Please excuse me as I don't know what those parts are called!]

This little concoction worked great for us. Dad has passed away but Mom has it on her night stand in case she needs help at night. I always thought this would be a great invention for someone.
