Home Automation Control

Question from customer: I want to install a single channel remote to control my doorbell within the range of 150m. The old 6V doorbell was broken and I don’t want to repair the wires of doorbell. Ordinary wireless doorbell cannot be used because it doesn’t reach the distance I really want. 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 150m. Would you like to recommend some favorable products? Answer : We recommend the 6V one channel 2000m receiver (S1U-DC06-ANT2) and long range transmitter (CB-1). Working voltage range of receiver is 6V. 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 6V doorbell. Usually, you don’t have to supply additional power to doorbell because it can get 6V power from powered receiver when you connect them to the 6V power supply together....

In a switch where the contacts remain in one state unless actuated, the contacts can either be normally open (abbreviated “ n.o. ” or “ no “) until closed by operation of the switch, or normally closed (“ n.c. ” or “ nc “) and opened by the switch action. Our remote receiver can be grouped into two types according to its current output modes. They are normally open/closed switch connection or current direct output connection (Controlled device can get power from powered receiver directly). Recently, one customer sent a picture of “Normally Open/Closed Receiver Connecting to an AC Lamp” to us to ask whether it is correct or not. Unfortunately, it is a wrong wiring. Please see a red cross to the lamp wiring from the following picture. This red cross points out the wrong wiring. AC lamp should not wire to the normally open terminals of receiver because there is no current through them which are only equivalent to a switch. The correct wiring is as follow. This is the 1 channel nor...
