I suppose you will need to find a manufacturer that doesn't have the restriction or find one with a "repeater" type adapter to link 2 loops. In real life I would expect a home that big to have a real alarm system. Even my wife's micro mansions (2000-4000 sq/ft) had a system that picked up the smokes, CO, pool alarm and intrusion alarm.
I just inspected a home that had a need for 31 yes THIRTY ONE, smoke alarms and while it appears that it would be possible to interlock them electrically with some sort of relay system- the manufacturers tell me that that's not allowed due to the listing. As for a Fire alarm system- The State of Michigan will recognize it as satifying the requirements as called out in the Michigan Residential Code (same as the IRC only with the Michigan spin).
As I understand it, that third wire only links some contacts together ... it there's continuity in one detector, they all sound off.
Yes that true John but if you have third wire interconneted and also the netural line as well as common return [ i have little trouble to grasp this idea how it work ]
but for hot's line it can be on common or diffrent phase or leg but i am sure but not excat answer for this one but i am thinking out loud that both red [ interconnection ] and white wires to actavie it
