The EMOS P5750.2R Wireless Doorbell in red and white is a compact, plug-in chime unit with a separate wireless transmitter. Designed for residential and small-office entrances, the system operates on a 433.92 MHz frequency and delivers a maximum audible level of 110 dB to ensure incoming visitors are heard even in noisy environments. The chime unit is mains-powered with an internal backup battery, while the transmitter is battery-operated and sized for easy wall or surface mounting.
