Overview
The Ajax SpaceControl Jeweller is a four-button key fob for arming and disarming an Ajax alarm as you leave and arrive, without opening the app or walking to a keypad. The fourth button is a panic button for emergencies. It suits anyone on an Ajax system who wants a fob on their keys: family members, staff who open up a shop, or an older relative who does not use a phone.
Is it right for you?
- It suits a home or small business on an Ajax system that wants one-press arming, disarming and Night Mode from a pocket fob.
- It can be assigned to a user and to a security group, so events show under that person’s name and the fob only controls the areas they are allowed to.
- 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; the Ajax compatibility list covers other hubs.
- If you want to change what the buttons do, note that command modification is only available with uartBridge, not with an Ajax hub.
Key features
- Four buttons: arm, disarm, Night Mode and panic.
- Accidental press protection by long or double press, on fobs with firmware 5.54.1.0 or later made from 19 March 2020.
- One CR2032 battery, pre-installed, with a calculated life of up to 5 years.
- Jeweller two-way radio with encryption and frequency hopping, up to 1,300 m to the hub or range extender in open space.
- Small and light: 65 × 37 × 10 mm and about 13 g, in black or white.
- Rated IP50 and IK04, for -25 to 50 °C, so it copes with a cold car or a hot pocket.
- Can be deactivated in the app without deleting it, for example if it is lost: a deactivated fob no longer sends commands and its panic button is disabled.
What else you need
An Ajax hub or range extender from the compatible list and the Ajax app, where the fob is added and assigned to a user and a group. Nothing else is needed; it carries its own battery.
Installation
No fitting: add it to the hub in the Ajax app and hand it to the user. An Ajax installer can do this when commissioning the system.
Software and licences
The fob is added, assigned and deactivated in the Ajax app. Buttons cannot be reassigned when it is paired to an Ajax hub.
Before you buy
- Choose black or white.
- Button functions are fixed when used with an Ajax hub: arm, disarm, Night Mode and panic.
- The panic button of a deactivated fob is also disabled, so deactivate a lost fob promptly in the app.
- Accidental press protection needs firmware 5.54.1.0 or later.

Questions about this product
Does it need an internet connection?
No. It sends commands to your Ajax hub by Jeweller radio. The hub needs its own connection for app notifications.
How far does it work from the hub?
Up to 1,300 m in open space to the hub or a range extender. Walls reduce this.
What battery does it use and how long does it last?
One CR2032, pre-installed, with a calculated life of up to 5 years.
Can I stop it sending alarms by accident?
Yes. Accidental press protection by long or double press is available on fobs with firmware 5.54.1.0 or later.
What if I lose the fob?
Deactivate it in the Ajax app. It stays in the system but stops executing commands, and its panic button is disabled.
Can I change what the buttons do?
Not with an Ajax hub. Button reassignment is only available when the fob is used with uartBridge.
