One to Many Remote Control System

Lisa is an electrical supervisor for Lighting Services Company. They are a big installer of festive lighting and have been asked by some of their clients if they can supply remote switch to turn on and off all the lights which are controlled at the same time. She needed 1 transmitter and 8 receivers all working on the same channel. The receivers will need to 240v and be capable of controlling 980 watts lights totally. She wondered if there is a system with one transmitter and 8 receiver units with antenna.
So she was looking for any favorable products on the internet. She found a kind of one to many remote control system.
This control system operating voltage is AC110~240V. It is very favorable for this customer’s need.
They are long range remote control kit.
Lisa wanted to prepare 1 transmitter and 8 receivers to control 8 lights simultaneously like the following picture.

Each of receivers will be paired with a light.
Wiring operation is fairly simple. Lisa told me the method which the supplier showed to her.
Wires from light are supposed to be connected to the output terminal of the receiver. We do it one by one. And receivers must be all powered by 240V power supply.
Here is the demonstration from the supplier.



Pressing the big button, 2 lights will be turned on simultaneously.

 

Pressing the small button, 2 lights will be turned off at the same time.
