CX/RX1000A Magnetic Door Contact


The CX/RX1000A is an indoor, wireless, magnetic door-contact transmitter system. The system only alerts when the door to which it is attached is opened, so it will not be triggered by people walking by or around the entry area. This unit also has a push-button option which may be used at counters or registers as a “ring for service” option. This is a simple, low cost wireless door announcing system, perfect for announcing entry, or when a “ring for service” option is required.

The CX1000A (transmitter) is a two-piece system that includes the sensor and a magnet. The transmitter attaches to the door frame while the magnet attaches to the door. When the transmitter separates from the magnet (as when the door opens), it sends a wireless signal to the receiver (RX), which then chimes. There are four tones from which to choose, and the tones are changed via the transmitter.

The CX1000A also has a push button option, which can be used at a counter or cash register as a “ring for service” option. The CX1000A is small and easy to mount on the door or at the counter with double-sided mounting pads, which are included. No tools required. CR2450 button battery is also included.

The CX/RX1000A is made in the USA, and warranted for one year, with a 30-day money back guarantee.
