KeyPad is a wireless indoor touch-sensitive keyboard managing the Ajax security system. Designed for indoor use. With this device, the user can arm and disarm the system and see its security status. KeyPad is protected against attempts to guess the code and can raise a silent alarm when the code is entered under duress. Connecting to the Ajax security system via a secured Jeweller radio protocol, KeyPad communicates with the hub at a distance of up to 1,700 m in line of sight.
