The Ajax SpaceControl White represents a key accessory for controlling the basic daily routines of your electronic alarm system without relying on smartphones. This compact bidirectional device features an elegant, high-impact glossy white finish. Its lightweight, highly ergonomic design easily attaches to any daily key ring. It delivers flawless arming and disarming actions from a safe distance.
The defining layout advantage of this key fob is its bidirectional radio communication with LED light confirmations. When triggering any security action, the bright LED blink confirms that the command was successfully executed by the hub. This ensures permanent peace of mind. It also integrates a dedicated emergency panic button. In critical safety situations, it sends an immediate, high-priority distress alarm.
The key fob avoids accidental key triggers in pockets or bags through advanced hardware safeguards. Users can configure the device settings to trigger alarms only upon double-clicks or prolonged presses of 1.5 seconds. Data transmissions rely on the proprietary Jeweller radio protocol. This wireless solution integrates robust AES block encryption to counter cloning attempts. It delivers an operational range of up to 1300 meters.
The key fob is paired with the central security panel very quickly. Scan the printed QR code using the official ajax mobile application layout. It is fully compatible with the brand's hubs and ReX range extenders. Check out our selection under Ajax kits and hubs to expand your security setup.
