ABOUT BRAND

Product Description

The MCMR-3000 Built-in Wireless Relay Receiver provides intelligent wireless control for two independent electrical circuits from a single compact receiver. Designed for concealed installation inside junction boxes and wall boxes, it upgrades conventional electrical installations with reliable wireless operation while preserving the original appearance of the room.

Operating on System Nexa 433.92MHz RF technology, the receiver communicates with compatible remote controls, wall transmitters, Nexa Smart Hub and Nexa Bridge. It can also operate alongside conventional 230V wall switches, allowing both manual and wireless control.

Each channel is equipped with a zero-crossing relay, reducing electrical stress during switching and helping extend relay service life. The receiver also supports Smart Mode, allowing favourite automation scenes to be stored and activated quickly using compatible Smart Mode transmitters.
