Need to put an alarm buzzer (outside rated) on an external stucco wall. The buzzer has a 3/4 opening on the back of the 4x4 cast housing for a standard conduit / flex fitting or strain wire clamp / bushing.
Have outdoor (NEMA 3, I think) 6x6x4 box.
Buzzer needs to face away from stucco wall.
So, how best to mount these? If I use NEMA box, cover is on face (away from wall), and I don't think you can mount anything on a cover (inspector might not like that : -). Any other surface faces the buzzer in a direction other than away from the wall.
If I mount the buzzer directly on the wall, this puts the 3/4 hole against the wall. Is it acceptable to put conduit or flex through the wall directly to the back of the buzzer?
