The Ajax SpaceControl is a wireless key fob that allows you to manage your security system and trigger panic alarms from a distance. It features four buttons and connects to all Ajax hubs, range extenders, ocBridge Plus, and uartBridge using the proprietary Jeweller wireless technology, which provides a communication range of up to 1,300 meters in open spaces. To ensure a stable connection, the device uses block encryption with a dynamic key and supports frequency hopping to prevent interference or jamming. Measuring 65 x 37 x 10 mm and weighing only 13 g, this compact black device fits easily into a pocket or on a keychain. It is powered by a single CR2032 lithium battery that can last up to 5 years, and it is designed to operate reliably in temperatures ranging from -25°C to +50°C with humidity up to 95%. Depending on the firmware version, you can prevent false alarms by using a long press or a double press, and the panic button functionality can be deactivated if it is not needed for your specific setup.
