Key Features: Zero False Alarms - the Double Button features two buttons that should be pressed simultaneously to raise an alarm. The plastic divider prevents accidental pressing when carrying DoubleButton in a pocket or bag. Guaranteed Alarm Delivery - DoubleButton communicates with a hub via Jeweller radio protocol at a distance of up to 1,300 m. Jeweller encrypts all the transmitted data. In the case of signal interference or radio jamming, the Ajax system switches the radio frequency and notifies the security company and users about the situation.
