Elderly people living alone - and their families - can find peace of mind and security with the two-way transmitters which connect to Yad Sarah's computerized communication center in Jerusalem 24 hours a day 365 days a year. A touch of a button (worn on the wrist) automatically activates a voice connection with the control room where a screen flashes the caller’s name, address, medical details, languages spoken, phone numbers of relatives, neighbors who have keys, doctor, nearest first aid station, etc. The caller can speak from any room in the house. The duty operator sends help as needed, and has been trained to calm a frightened person. Thousands of Israelis are connected to Yad Sarah in this way, and lives have been saved by this service.

Anyone can connect to this service, for a one-time payment of 300 NIS (for insurance and back-up batteries) and a refundable deposit of 300 NIS. There is no further monthly fee. Installation, repairs, and operator duty are done by volunteers.
