The RT28E5001-11-23K push-button transmitter from ELDAT is a wireless push-button transmitter designed for use in personnel calling systems and light calling systems. It features a robust, functionally designed housing in anthracite finish with a large, grey operating button, enabling simple and secure operation. The transmitter is designed for indoor use and primarily serves to switch electrical loads via a single-button operation. Another typical application is its use as a doorbell button in combination with the wireless gong RCP04. The functionality is based on the Easywave standard with an operating frequency of 868 MHz, ensuring reliable wireless communication within home and building automation systems.

Applications
This push-button transmitter is suitable for use in residential and commercial spaces, as well as in elderly and care facilities, where simple and intuitive control of electrical devices or calling systems is required. It can be used, for example, to control lighting circuits, blinds, or other electrical loads. In care facilities, it serves as a call button to alert care staff when needed. Its use as a doorbell button in combination with the wireless gong RCP04 also makes it suitable for entrance areas or apartments.

Functions and Equipment in Detail
The transmitter supports the functions 1 x impulse" and "toggle. In impulse mode, a single, short signal impulse is transmitted as soon as the button is pressed. The toggle function allows switching the state of a connected device—for example, turning a light on and off by pressing the button once each time. This functionality is particularly useful for applications requiring simple, two-state control. The large operating button ensures excellent visibility and ease of use, even for individuals with limited motor skills.

Technology Explained Simply
The push-button transmitter operates in the 868 MHz frequency band, which is used in the Easywave standard. This standard is widely adopted in Germany and other European countries and enables stable, interference-free wireless communication over short to medium distances. Wireless transmission eliminates the need for visible cable connections, allowing for flexible installation. The IP65 protection rating ensures the transmitter is dust-tight and protected against water jets from all directions, making it suitable for use in damp or lightly soiled environments.

Compatibility and Accessories
The push-button transmitter is compatible with systems supporting the Easywave standard, particularly with the wireless gong RCP04. It can be integrated into existing building automation systems based on the Easywave protocol. Use with other devices requires matching the same radio frequency and communication standard.

Mounting and Installation
Mounting is carried out at a suitable wall or surface location, with positioning chosen so that the large operating button is easily accessible. Installation requires no special tools or additional components. Wireless communication operates without cable connections, so no electrical connections are required at the transmitter itself.

Operational Advantages
The push-button transmitter provides simple, wireless control of electrical loads and calling systems. Its robust construction and IP65 protection rating ensure high durability and reliability, even in demanding environments. The clear, large operating surface facilitates use, especially for older or mobility-impaired individuals. The functionality with impulse and toggle modes expands application possibilities and allows flexible adaptation to different requirements.
