DoubleButton is a wireless hold-up device featuring two tight buttons and a plastic divider to protect against accidental presses. When pressed, it activates an alarm (hold-up event) transmitted to users and the Central Monitoring Station (CMS). An alarm can be triggered by pressing both buttons: one-time short or long press (more than 2 s). If only one of the buttons is pressed, the alarm signal will not be transmitted. All DoubleButton alarms are recorded in the Ajax app’s notification feed. The short and long presses have different icons, but the event code sent to the monitoring station, SMS, and push notifications do not depend on pressing. DoubleButton can only operate as a hold-up device. Setting the type of alarm is not supported. Keep in mind that the device is active 24/7, so pressing the DoubleButton will activate the alarm regardless of the system security mode. To send alarms and commands to the control panel, DoubleButton uses secure Jeweller radio protocol. It provides an uninterrupted two-way communication between Ajax wireless devices and the hub. . This is a two-way wireless data transfer protocol that provides fast and reliable communication. Jeweller supports floating key block encryption and verifies each communication session with devices to prevent sabotage and forgery. You can use DoubleButton at a distance of up to 1,300 m from the control panel without obstacles. The device features a record-breaking operating efficiency with up to 5 years of battery life.
