I'm not sure where you are located, but I'm in the United States and had Lifeline Alarm system for my parents -- a wonderful and very helpful tool. You can have it set up to call an emergency line, then anyone else who needs to be contacted (it was me and my sister.) When my Mom went on Hospice, we had her necklace alarm changed to call Hospice, and then as time went on same with my Dad. It worked so well, and you can either push the button on the alarm box or on the necklace they give them. A person stays on the line the whole time until the emergency medical team shows up. It's great and I highly recommend it!
