I am in the process of wiring a fire station, when they get a emergency call, an informer system is suppose to turn on certain lighting via contactor. Would I use some kind of transfer relay for each circuit to accomplish this? What do you think?
I have done one of these before, you just parallel a control relay with the exsisting light switch. The one I wired had a reset button on Informer controller that returned everything to normal when pushed.
