Ajax DoubleButton: a panic button that does not trigger by accident
A wireless panic button with two buttons that you press at the same time to raise the alarm. A plastic divider between the buttons prevents the alarm from being triggered by accident, even when you carry the DoubleButton in your pocket or bag.
Because you have to press both buttons deliberately at the same time, the chance of a false alarm is practically ruled out. The DoubleButton also supports confirmed alarms: if you press in an agreed sequence, the alarm receiving centre can be certain that the alarm was raised deliberately and by an authorised person. An LED indication confirms that the signal has been delivered.
Why the DoubleButton
Raise the alarm deliberately
Two buttons that you press at the same time, so that an alarm is always a deliberate choice.
No false alarms
A plastic divider between the buttons prevents the DoubleButton from being triggered in a pocket or bag.
Confirmed alarm
An agreed sequence makes it clear that the alarm is raised deliberately and by an authorised person.
Years on a single battery
Up to 5 years on the pre-installed CR2032 battery. The app warns you well in advance.
