EMOS P5731 is a wireless doorbell in white designed for AC mains operation (230 V). The set includes a wireless transmitter button and a mains-powered chime unit that communicates on the 433.92 MHz frequency. With a nominal sound level of 90 dB and a quoted wireless range up to 180 m in open space, this doorbell is intended to provide clear audible notification of visitors or deliveries without running wires between the push button and the chime.

Advantages

The EMOS P5731 offers straightforward installation thanks to its wireless transmitter and mains-powered receiver, eliminating the need for wiring between the two units. Its 90 dB chime delivers a loud, easily heard signal suitable for typical residential or small-office environments. Operating on the common 433.92 MHz frequency with a specified range up to 180 m allows flexible placement of the transmitter relative to the receiver within that distance under favorable conditions.

Suitable for

• Private homes and apartments where a mains-powered indoor chime is preferred
• Small offices, reception areas, and shops requiring audible visitor notification
• Situations where wireless installation is needed to avoid running cables

How to use

Mount the wireless transmitter near the entrance at an accessible height and secure it using the supplied adhesive, screws, or mounting bracket as appropriate. Connect the chime unit to a standard AC 230 V mains outlet indoors and place it where the sound can be heard throughout the intended area. Pairing between the transmitter and receiver follows the manufacturer’s procedure: activate the receiver pairing mode and press the transmitter button to establish the wireless link. Test the doorbell after installation to confirm the audible signal and adjust the receiver position if necessary to improve reception.

Usage recommendations

For reliable operation, install the chime away from large metal objects and appliances that may cause radio interference. When estimating placement, remember that the quoted 180 m range applies in open space; walls and other obstructions can reduce effective range. Use inside environments for the mains-powered chime and protect the transmitter from direct exposure to weather if it is not specified as weatherproof.
