With the Guardian Alert 911 Plus you can communicate with a 911 operator at the push of a button anytime, anywhere, without a landline or cell phone. The pendant can be worn around your neck, wrist or in a belt clip on your waist. With this new technology the coverage area is expanded to allow more freedom and more mobility. You will be able to reach 911 operators 24 hours a day, 7 days a week no matter where you are at the push of a button. When the emergency button is pressed you are connected to the 911 operator and able to have a 2 way conversation through the pendant.
