The Ajax Double Button transmits a signal to the hub via Jeweller—a two-way radio protocol communicating at a range of up to 1300 meters. 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. Double Button 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 Double Button in a pocket or bag.
