Product Description

The Visonic MCT-320 is a fully supervised, compact PowerCode™ door/window contact transmitter, designed primarily for protecting doors and windows using a built-in magnetic contact that operates in conjunction with a magnet to detect the opening and closure of a door or window.

Suitable for any residential or commercial environment this low-profile transmitter gives the added advantage of a particularly small size that allows for highly flexible and virtually invisible installation.

When activated, the magnetic contact initiates an individual 24-bit PowerCode ID message, which identifies it to the target receiver as a separate transmitter. Each ID code is randomly selected from 16 million possible combinations, and is therefore unique and virtually impossible to accidentally reproduce.

A smart anti-collision algorithm prevents signal jamming by simultaneous transmission from multiple devices. Periodic transmission of supervision signals is used to confirm system connectivity at all times.

MCT-320 is available in several optional frequencies in compliance with European, U.S. and other international standards. The transmitter is powered by a standard long-life lithium battery, which is constantly monitored, with automatic reporting to the receiver when the battery needs to be replaced.
