You don't want to take chances when it comes to your loved ones' safety. That's why it's important that they get emergency help when it's needed most. The Guardian Alert 911 is an automatic dialer that lets you talk to emergency medical personnel when you press the button on the included wireless pendant that you can wear around your neck. Since it uses your existing phone line, there are no monitoring fees, service charges or contracts required. Emergency Alert System Is a Tiny Speakerphone Unlike pre-recorded emergency dialers, the Guardian Alert 911 is a tiny cordless speakerphone that lets you speak directly to a 911 operator with the press of a button. Wear it around your neck on the included lanyard, clip it to your belt, or keep it in a pocket. The system can operate anywhere in and around your home by triggering the base station that's plugged into a phone jack. A telephone line splitter is included in case you need to use a single phone jack for both the base unit and a conventional phone.
