Operating principle

DoubleButton is a wireless hold-up device, featuring two tight buttons and a plastic
divider to protect against accidental presses. When pressed, it raises an alarm
(hold-up event), transmitted to users and to the security company's monitoring
station.
An alarm can be raised by pressing both buttons: one-time short or long press
(more than 2 seconds). If only one of the buttons is pressed, the alarm signal is not
transmitted.
