Ajax DoubleButton Jeweller is a wireless panic button whose alarm is raised only when both buttons are pressed at the same time. An accidental alarm is therefore all but impossible, so the button can be carried in a pocket or bag.
The alarm reaches the monitoring station and the user's phone silently, so in a dangerous situation the button does not give itself away. The event type can be chosen in the app: panic button, medical assistance, intrusion, fire or a custom event.
An LED confirms that the alarm reached the hub. The button can be worn around the neck, attached to keys or fixed with the included holder under the edge of a counter. Communication is encrypted, device authentication protects against spoofing, and the pre-installed battery lasts for years.
