4-channel radio key transmitter Type: RNK-04 EXF10000026

Radio key transmitter – versatile control at your fingertips

This 4-channel radio key transmitter RNK-04 is the heart of the Exta Free wireless control system. It allows convenient management of various functions in your home or company – from simple turning lights on and off, through brightness adjustment, to controlling blinds or time devices. Thanks to its compact size and battery power, installation is extremely simple and flexible – you can place it almost anywhere, even on glass or wood.

Functionality and ease of use

RNK-04 is not only a remote control, but an element of a comprehensive system. It allows independent control of up to four Exta Free receivers, which means you can control many different circuits with one device. Optical signaling informs about sending a signal and battery status, and a large operating range (up to 300 meters in open space) ensures comfortable use even in large facilities. Battery power (3V DC, type CR2032) guarantees long-term operation – even up to 5 years, depending on usage intensity.

Installation and application – simple and trouble-free

The transmitter installation is trivially simple. You can attach it with double-sided adhesive tape or use expansion bolts (5x(3x30) mm). The device operates in the 868 MHz band and complies with safety standards. It is ideal for both new installations and modernization of existing systems. Thanks to the universality of the Exta Free system, RNK-04 will find application in many scenarios:

• Lighting control (on/off, dimming/brightening)
• Automation of blinds and shutters (raising/lowering)
• Operation of time devices
• Remote control of entrance gates and garage doors (in combination with appropriate receivers)
• Integration with Exta Life smart home systems (requires compatible receivers and controller)

Additionally, the transmitter meets the requirements of directive 2014/53/EU, which confirms its compliance with European standards.
