LITTLE ROCK, Ark. (AP) - Arkansas residents can sign up for a system known as Smart 911, which is designed to make medical information available to emergency responders. The system can also make it easier for paramedics and police to find the address of someone calling from a mobile phone. 

The system is being installed in 911 systems across the state. 

People can open a free, password protected account at the Smart 911 website, entering allergies or other medical conditions and listing an address. Calls to 911 made from mobile phones only give dispatchers a general location of where the call originated. 

Officials stress that users have to keep their information current. 

The system also comes with privacy protections that block access to a user's information unless he or she has an active 911 call.
