Wireless CodeSecure™ Keyfob Transmitter
The MCT-234 is a miniature CodeSecure™ 4-button (4-function) transmitter, designed for use with advanced, high-security alarm and remote control systems.
Transmission is initiated by pressing any one of the four recessed pushbuttons. Upon pressing a specific button, the MCT-234 transmits a CodeSecure™ digital sequence identifiable by compatible CodeSecure™ receivers, and a 4-bit function code associated with the button that was pressed.
The next time a button is pressed, the MCT-234 will transmit a digital sequence that differs from the one used in the previous transmission and the respective function code. As a result, malicious “code grabbing” is virtually impossible.
Operating power is obtained from an internal 12 V alkaline battery. A red LED lights during transmission as long as the battery voltage exceeds 8.6 V. If the LED flashes during transmission, the battery must be replaced without delay. In addition, a “low battery” report will be transmitted with the outgoing digital message. Compatible receivers are designed to identify this report and operate a corresponding output.
