The Visonic MCT 234 is a miniature PowerCode 4-button wireless key fob transmitter designed for use with alarm and remote control systems, such as Visonic Ltd's MAX-20 MC and PowerMax.

Whenever one of the 4 specific push-buttons is pressed, the Visonic MCT 234 transmits a Code-Secure digital sequence that is identifiable by compatible PowerCode receivers, together with a 4-bit function code associated with the button that was pressed. The wireless key fob transmitter signal is encrypted and changes in every transmission. As a result, "code grabbing" is virtually impossible.
