I'd like to know can I tap the signal line of one sd to feed multiple others? In other words instead of going sd to sd, can I connect the signal lines of two upstairs sd's to the last one downstairs?

If I'm understanding you correctly there is no difference where you tap as long as they are all connected together. __________________ Electricity will kill you if you give it a chance
