Wireless Hold-Up DoubleButton

Call us for a price


The DoubleButton is a wireless hold-up device, intended to be used to activate an alarm when in danger. To activate the alarm, you must simultaneously press both buttons. They are stiff and parted by a plastic barrier. These measures eliminate false alarms when carrying DoubleButton in a pocket or bag. Raising an alarm is the priority DoubleButton function, but not the only one. By transmitting an alarm signal, the hold-up device can activate all or specific sirens at the object. And also, run automation scenarios: trigger a smoke machine, close electric locks, lower roller shutters.
