Magnetic contact sensor for doors & windows

MCT-302 is a fully supervised PowerCode™ magnetic 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. This highly reliable top-performance wireless device is easy to install and operate in a wide range of residential and commercial environments.

An additional hard-wired, end-of-line (EOL) protected input can be used, with normally open (NO) and normally closed (NC) pushbuttons, sensors, contacts, switches and other detection devices, for a variety of security and control applications. The MCT-302 T offers an additional back tamper switch for detecting removal of the device from its mounting.

When activated, the magnetic contact and the auxiliary input initiate 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.

Each 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.
