The PowerMax range of wireless security solutions meets widely varied residential and commercial safety and security needs.  It is ideal for residential and small commercial properties which require simple and straightforward installation and protection requirements.

Based on Visonic’s PowerCode technology, the PowerMax family includes a variety of wireless control panels and wireless peripherals, including indoor/outdoor motion detectors, safety sensors and a wide range of personal emergency transmitters.  

MCT-234 is a 4-button miniature wireless CodeSecure keyfob transmitter designed for arming and disarming PowerMax wireless security systems, the MCT-234 can also activate a panic alarm signal when two buttons are pressed.

When activated, each button initiates a CodeSecure transmission of a unique 28-bit (rolling code) ID command, selected from over 100 million possible combinations. To prevent "code grabbing" by potential intruders trying to defeat the security system, the next time the button is activated, the transmitter sends out a different CodeSecure ID, which is selected by a proprietary code encryption algorithm and which can be recognized only by the target receiver.

This attractive miniature keyfob is powered by a 23A alkaline battery and features visible and transmitted low battery indications when the battery needs to be replaced.
