The Qolsys DSC MX975 is a state-of-the-art addressable hardwired magnetic door and window contact device that is designed to provide reliable and accurate monitoring of your doors and windows. This MX975 contact functions with MX panels and with receivers that use MX technology, ensuring seamless integration and enhanced security for your home or business. One of the standout features of the MX975 sensor is its addressable design. This means that each sensor has a unique address, allowing for precise identification and monitoring of individual doors and windows. This not only provides you with detailed information about the status of each entry point, but also allows for easy troubleshooting and maintenance. The MX975 sensor is hardwired, which means it is directly connected to your security system using a physical wire. This ensures a reliable and secure connection, eliminating the risk of wireless interference or signal loss. Additionally, the sensor comes with a magnet, which is installed on the door or window frame, and a corresponding sensor, which is installed on the door or window itself. When the door or window is closed, the magnet and sensor align, indicating that the entry point is secure. If the door or window is opened, the magnet and sensor separate, triggering an alert on your security system. In terms of installation, the MX975 sensor is designed to be user-friendly and easy to set up. It comes with all the necessary mounting hardware and detailed instructions, making it a hassle-free addition to your security system. The sensor is also compact and discreet, ensuring it blends seamlessly with your existing decor.
