The ROM-22 is the 2-channel modular radio receiver for the Smart Home Zamel EXTA LIFE system. It mounts on a DIN TH35 rail in the distribution cabinet and enables independent control of two devices or electrical circuits. The outputs consist of two changeover relays (NO/NC) with a maximum load of 10 A each — suitable for both low-voltage circuits (12/24 V AC/DC) and 230 V AC. Bidirectional RF 868 MHz communication ensures the status of each channel is always visible in the EXTA LIFE mobile app.
The ROM-22 modular radio receiver can be controlled by the EFC-01 controller via mobile app, or directly by EXTA LIFE transmitters without a controller. The 2 configurable wired inputs accept monostable or bistable switches, allowing existing physical controls to be retained. Firmware updates remotely via the controller without dismounting the device. The screw-mount antenna supports an external antenna — useful in metal enclosures or environments with weak signal
