DoubleButton

Wireless hold-up device

No accidental presses

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.

No unnecessary dispatches

DoubleButton supports confirmed alarms. This feature implies instructing users: what sequence of presses is required to generate a confirmed alarm condition. It gives a 100% guarantee that a hold-up alarm was raised intentionally and only by an authorized user.

More than just alarms

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.

The device body is resistant to temperature extremes, dust, and splashes. Buttons are designed for thousands of clicks. With a pre-installed battery lasting up to 5 years, DoubleButton does not require maintenance for a very long time.
