AJAX Wireless Double Button

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

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

The hold-up device transmits a signal to the 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

DoubleButton meets the requirements of professional European security standards and can be used in both private and commercial properties. Wireless connectivity with the hub and long communication range gives freedom in placing and allows you to carry DoubleButton around
