Overview

The Ajax Button Jeweller is a small wireless panic button that you can carry, keep on a bedside table or fix under a counter. One press sends an alarm through your Ajax system, with the alarm type set to what you need: intrusion, fire, medical help, panic or gas. It can also act as a smart button that switches Ajax automation devices. It suits homes, shops and clinics where someone may need to call for help quickly.

Is it right for you?

  • It suits a home with an elderly relative, a shop counter or a reception desk on an Ajax system.
  • Choose it as a smart button if you want a physical switch for a light, gate or appliance connected through Ajax relays or sockets.
  • If you need a hold-up button that cannot be pressed by accident at all, the DoubleButton needs both of its buttons pressed together.
  • It works with Hub (2G), Hub (4G), Hub Plus, Hub 2, Hub 2 (4G), Hub 2 Plus and the ReX and ReX 2 range extenders.

Key features

  • One button with adjustable event type: intrusion, fire, auxiliary alarm, panic, gas, malfunction, leakage or custom. A custom event is not sent to the monitoring station and does not trigger SMS.
  • Accidental press protection by long or double press in panic mode.
  • LED that confirms the command was delivered, with brightness adjustable in the app.
  • IP55, so it copes with splashes and dust in a kitchen or workshop; -10 to 40 °C.
  • One CR2032 battery, pre-installed, with a calculated life of up to 5 years; with OS Malevich 2.16 or later it reports its battery status daily.
  • Jeweller two-way radio with encryption and frequency hopping, up to 1,300 m to the hub or range extender in open space; communication loss detection after 36 s.
  • Tiny and light at 47 × 35 × 13 mm and 16 g, in black or white.

What else you need

An Ajax hub or range extender from the compatible list and the Ajax app. To fix it to a wall or under a desk, use the Ajax Holder, which is a separate item. For smart button use you need Ajax automation devices such as a relay or socket to switch.

Installation

No wiring. Add it to the hub in the Ajax app and choose its mode and event type. Carry it, or fix it to a surface with the Ajax Holder.

Software and licences

Mode, event type, LED brightness and accidental press protection are set in the Ajax app. A deactivated button stays in the system but stops sending commands and its panic function is disabled.

Before you buy

  • The Holder for fixing it to a surface is sold separately.
  • Choose black or white.
  • A custom event type does not reach the monitoring station and sends no SMS.
  • If you deactivate the button in the app, its panic function is disabled too.
