The Chime Box Receiver with Relay from Optex is designed to be used with the TD-20U Indoor/Outdoor Sensor Transmitter for transmitting RF signals up to 2000' away. The receiver can support up to nine TD-20U units, enabling you to create a full perimeter around your property. In addition, the RC-20U Receiver/Chime Box includes a Form-C relay for activating additional devices such as lights, cameras, and door locks.

\r\n\r\nWhen motion is detected by your sensor, the receiver will alert you by sounding an audible chime. You can choose to use any of three selectable chime tones, and when using multiple sensors, you can program a different chime tone to sound for every 3 sensors. The receiver is also compatible with TC-10U door contacts and TS-10U handheld push-button transmitters. Additionally, the system's transmission range can be extended by using the TR-10U Repeater.
