The product can be plugged into the socket as a replacement or supplement for the "ELDAT RCP04E5001-11", as both socket radio chimes are designed for the Easywave system with 230 V AC supply and offer optical and acoustic signalling. Both support the teach-in of up to 32 Easywave radio transmitters and are suitable for the D/A/NL/S/N plug systems. However, the newer model RCP24E5001A01-K offers 12 different call tones and an adjustable volume in three levels, while the RCP04E5001-11 has three melodies with an integrated flashing light. The dimensions and power consumption differ slightly, but the plug system and range of functions are compatible.
