The rf wireless distant control technology can be leisurely used to control lights from outdoor as well. There are 4 big ceiling lights installed on the ceiling of an indoor stadium which managed by a PE teaching headmaster from a primary school. He must go to touch the manual switches one by one when teachers had PE class in the indoor stadium. However, ceiling lights’ switch was installed on a wall outside of stadium gate. It is not convenient to him to go back and forth. So he would like to find effective way to solve this problem.
I think that he need a distant controller to deal with this situation. A 4 channel high power great range ac distant control kit is very favourable for him. It contains 4-channel high power ac output receiver and one great range 4-button remote transmitter. Working distance of this set is 2000m (6000ft) in the open air with external magnetic mount antenna. 4-channel remote control has 4 working modes. They are toggle mode, momentary mode, latched mode and momentary +toggle mode which will satisfy his different needs.
Wiring is fairly simple. Do as the following picture shows. Wire each spotlight to each relay; use transmitter to remote control them. Four buttons control corresponding spotlight respectively.
