Hi,
I have a 22K sqf office complex with a corridor that surrounds the interior rooms and there is several exits leading from the corridor to the outside.

I want to allow the occupants to control the lights from several locations throughout the corridor.

Is switching rows or groups of lights best accomplished by using three ways and four ways that will control a lighting contactor/s?

I am thinking of using this setup.

Any suggestions or comments would be appreciated.

-regards
