The CX 1000A is a magnetic door contact transmitter system designed for door announcement and security purposes. It has a 500-foot transmission range and is easy to install. However, it’s best suited for entrances that remain closed during business hours2.

For large, high-traffic stores, you might need a system that can handle multiple entry points and higher traffic volumes. Systems with more advanced features, such as motion detection or multiple chime options, might be more appropriate.
