Protection in real places.


Security controls that travel with you.
Four dedicated buttons
Arm the system, disarm it, activate Night Mode or raise a panic alarm using the separate controls. With an Ajax hub, their everyday security commands are fixed.
The panic button can be disabled in settings if the intended use requires it. SpaceControl does not offer a configurable automation button for each action.
Give the key fob a clear owner.
Assigned to a user
Assign the key fob to a person so its events are shown under that user’s name and its security-management rights follow their permissions.
Control a selected group
Configure the key fob for an appropriate security group where group mode is used. Check that the assigned person can manage that group before handing over the device.
Protect against an unintended press.
Long or double press
Choose the documented accidental-press protection when a key fob is carried in a pocket or bag. A long press is over 1.5 seconds; a double press is within 0.5 seconds.
Requires firmware 5.54.1.0 or later on the supported revision. The key fob’s firmware cannot be updated; check the supplied device in the app.
Keep a panic control close at hand.
A manually raised alarm
The enabled panic button sends an alarm to the system. Configure whether sirens should sound and agree monitoring and response arrangements with the provider.
Test the alarm procedure with the monitoring company. Carrying a key fob does not extend its radio coverage beyond the installed system.
Know what the status indication means.
CR2032 battery and command feedback
The preinstalled battery is specified for up to five years under the manufacturer’s use conditions. LEDs indicate command results and a low battery; their pattern depends on the firmware.
SpaceControl reports its status only after a button is pressed. It is not continuously polled, so a battery value shown in the app is the last reported state. Test it regularly and replace the battery when warned.
A secure link to your system.
Jeweller communication
Jeweller carries commands, alarms and device status between the control and a compatible Ajax hub or assigned range extender. Encrypted communication and device authentication help protect the exchange.
Up to 1,300 m in open space. Walls and metal reduce usable range; check operation at every intended location. Choose equipment for the same radio-frequency region.
A registered control for one system.
Device authentication
Encrypted communication and device authentication help prevent a different device from impersonating the paired key fob. Remove a lost key fob from the system and review its user permissions promptly.
The enclosure is rated IP50 and IK04. Protect it from water; it is not a splashproof substitute for Button or DoubleButton.
Ready for everyday use.
