No accidental keystrokes

To cause an alarm, you must press both buttons simultaneously. They are rigid and are separated by a plastic divider. This eliminates false alarms when carrying the DoubleButton in a pocket or purse.

No unnecessary shipping

DoubleButton supports acknowledged alarms. This feature involves teaching users what sequence of keystrokes is necessary to generate a confirmed alarm condition. This gives a 100% guarantee that a robbery alarm was triggered intentionally and only by an authorized user.

  • Confirmation with 2 DoubleButton

Guaranteed alarm sending

The robbery button transmits a signal to a hub via Jeweler, a two-way radio protocol that communicates at a range of up to 1,300 meters. A flashing LED verifies the correct sending of the DoubleButton alarm. Jeweler encrypts transmitted data and prevents device spoofing. In the event of interference, the Ajax system switches to a free radio frequency and, when communication is inhibited, notifies users and an alarm receiving center of the situation.

PRO technological solution for any installation

DoubleButton meets the requirements of European professional safety standards and can be used on both private and commercial properties. Wireless connectivity to a hub and wide communication range give you freedom of placement and allow you to take the DoubleButton with you everywhere.

More than alarms

Raising an alarm is the priority feature of DoubleButton. But it is not the only one. By transmitting an alarm signal, the hold button can activate some or all of the sirens on the object. And you can also run automation scenarios: activate a smoke machine, lock electric locks, lower roller blinds.

Effortless maintenance

The device's casing is resistant to extreme temperatures, dust and splashes. The buttons are designed for thousands of keystrokes. With a pre-installed battery that lasts up to 5 years, DoubleButton is maintenance-free for a long time.
