Information

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.

Guaranteed alarm delivery

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.

  • Radio signal range of up to 1,300 m
  • Alarm delivery confirmation
  • AES encryption
  • RF hopping

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 the hub and long communication range gives freedom in placing and allows you to carry DoubleButton around.

  • Under the desk in a workplace
  • In a clerk's pocket
  • On a guard's neck
  • On the wall by a front door or bed

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.

Add DoubleButton to a system and configure it — all in Ajax PRO — a mobile app for engineers. No need to disassemble the housing; just fix the device to a surface using Holder (Sold separately). Or hang it on lace or keychain. A few minutes and hold-up device is ready for use.
