Looking for some clarification on smoke wiring - 1 family residential. Have 6 smokes/CO all hardwired /interconnected using 3 wire. These will be added to general lighting circuit, hallway lights, etc. as long as they're interconnected, it does not matter where in the series I draw from the gen light circuit that will be feeding them, correct? 1st, 2nd floor or basement, wherever the closest line is on that circuit? Thanks
