Wireless hold-up device.
No accidental presses
To raise an alarm, you must simultaneously press both buttons. They are stiff and parted by a plastic divider. That eliminates 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.
Guaranteed alarm delivery
The hold-up device transmits a signal to a hub via Jeweller — a two-way radio protocol communicating at a range of up to 1300 meters. A flashing LED verifies the successful delivery of the DoubleButton alarm. Jeweller encrypts the transmitted data and prevents device forgery. In the case of interference, the Ajax system switches to a free radio frequency, and when the air is jammed, it notifies users and a security company about the situation.
PRO-technology solution for any object
DoubleButton meets the requirements of professional European security standards and can be used in both private and commercial properties. Wireless connectivity with a hub and long communication range gives freedom in placing and allows you to carry DoubleButton around.
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.
Truly effortless maintenance
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.
