Question from customer:
I want to install a single channel remote to control my doorbell within the range of 100m. The old 12V doorbell was broken because of the construction which cannot be repaired. Ordinary wireless doorbell cannot be used because of distance. I have an idea that a transmitter is connected to the doorbell button and relay in receiver is connected to doorbell. The only problem is the control range of remote need to reach about 100m. Would you like to recommend some favorable products?
Working voltage range of receiver is 12V. With normally open and close terminal, the voltage of the device being controlled is AC110~240V or DC0~28V. So it can be applied in 12V doorbell. And the most significant is that it has extended external antenna which makes its control range up to 2000m (6000ft). You will be satisfied with this product.
According to your requirement, you can connect the button of the bell to the transmitter by two wires. Then connect the bell to the relay in the receiver.
Setting control mode Momentary: Connect Jumper-1.
When you press the button of the bell, RF signal will be sent out from transmitter to receiver. The receiver receives to turn on the relay, then the doorbell rings. Release the button, the doorbell stops ringing.
