Double button is a wireless hold-up device for sending a confirmed hold-up event to an alarm receiving center. Featuring both physical and software protection against accidental presses, Double button can be used as a key fob or fixed on a surface. PD 8662 Compliance
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 the Double Button in a pocket or a bag.
No Unnecessary Dispatches
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.
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 Double Button 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.
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, Double Button does not require maintenance for a very long time.
