No wires, no limits.

20 years service life.

280 meters transmission distance.

Excellent sound quality.

Tech Intro                                                      

 

Transmitters use the unique PUSH-RF technology which is the energy harvesting wireless technology and ultra low power technology. When the button is pressed, it will trigger the micro-generator, the direction of the magnetic circuit in the micro-generator would change. The rapid magnetic flux change leads to an induced voltage, in other words, mechanical energy is changed into electric energy.

RF-transceiver of the receivers receive the wireless signals, microcontroller identifies the signals. If the signals are right and the pairing between receiver and transmitter is successful, the music chip in the receivers will be triggered; then the loudspeaker plays beautiful music to tell the host there’s a visitor waiting at the door.

Features &benefits：

 

1.      No battery, no pollution.

Require no batteries, wouldn’t cause the soil or water pollution.

2.      Never need to change batteries, maintenance-free.

You will never need to buy or change batteries, more convenient, save your time and cost.

3.      20 years service life

Thanks to the super long service life, you wouldn’t have to buy a new doorbell every 3 years.

4.      280 meters transmission distance. Signals could pass through doors, walls and floors.

Its excellent performance could meet quite complex requirement. Even the receiver is on the fifth floor, it works properly. Typical uses are in homes, factories, restaurants, hotels and office buildings.

5.      Require no wiring. Easy installation.

Transmitters can be mounted with screws or double faced tape. Receivers plugs into any standard wall outlet.

6.      Self-learning code system automatically adjusts to eliminate interference.

Long press the function button until the indicator light out, self-learning mode open. Then pressing the doorbell button twice, if the indicator light flash and the doorbell rings, the pairing between transmitter and receiver is successful. If not, you need to press the doorbell button twice again.

7.      Loud enough volume, up to 85 dB. You can hear it in any room.

8.      16 chime sounds, built-in amplifier, good sound quality makes it pleasant to hear.
