Wireless doorbell EMOS P5729 (model 3402044000) — battery-powered transmitter and receiver set

Wireless Doorbell EMOS P5729 (model 3402044000) is a battery-free transmitter and mains-powered receiver set designed for quick installation and reliable operation. The transmitter (button) generates the signal mechanically when pressed, while the receiver plugs into a 230 V socket and reproduces one of 36 selectable melodies at up to 90 dB. Automatic pairing and a memory function preserve settings after power interruptions. The device operates on 433 MHz and provides a wireless range up to 180 m in open space. A blue LED on the receiver indicates activation when the bell is triggered.

Advantages

Automatic pairing simplifies setup: the transmitter and receiver pair within about 25 seconds after the receiver is connected to the socket. The transmitter requires no batteries because the press generates the transmission energy. Long-term memory in the receiver keeps melody and volume settings after power loss. The receiver offers 36 melodies and four volume levels, and the system supports adding up to six additional transmitter buttons. The button is water-resistant for outdoor use, and the receiver indicates activation with a blue LED.

Suitable for

• Private homes where a simple, battery-free doorbell button is preferred
• Small offices and retail premises that need easy installation without wiring
• Entrances exposed to weather due to the water-resistant transmitter button
