i'm in need of all the brainy sparkies out there

i have a job in a set of offices where they want a master or control switch at the front door so when they leave they can turn all lights off.

but they also want to be able to walk into one office and turn that light on independently of the master switch. in other words whether or not the front reception master switch is on or off you can turn one office light on and then walk out the front door and turn the same light (and any others) off.

been racking my brains but haven'y yet sussed out how to accomplish this

all help would be appreciated

i'm sure there is an answer
thanks guys

No problemo. Use a GE RR-7 system. Been in use since the 1950's.

Most major panel manufacturers are now making lighting control panels with all kinds of features to do stuff like this and a whole lot more.
