To raise the alarm, you need to press two DoubleButton buttons at the same time. The buttons are tight and separated by a plastic partition. False alarm when carried in a pocket or bag is not possible.
DoubleButton supports confirmed alarms. This feature provides instruction to users: what sequence of clicks to raise the alarm. And gives a 100% guarantee that the alarm was deliberately raised by an authorized user of the system.
The emergency button transmits the hub signal via the two-way Jeweler radio protocol. Communication range up to 1300 meters. Successful delivery of the DoubleButton alarm confirms the LED flashing. Jeweler protects the transmitted data with encryption and prevents tampering with the device. If there are interferences in the network, the Ajax system switches to free radio frequency, and in case of jamming the air notifies users and the security company about the situation.
