Old thread, but is pretty much what I was looking at. I'm going to wire them separately to each side I believe.
How does having interconnected units cause MORE false alarms? If the smoke alarm is going off, it's just that all of them will go off instead of just 1. I suppose a little more annoying false alarm, but a heck of a lot better if it's a real fire!
I've rewired my residents with interconnected smoke alarms and remodeling a duplex now that doesn't have anything, so will be adding interconnected smoke alarms.
Yes, you can do the battery only powered, but they are usually more expensive, even more so if you get the interconnected ones which I feel are safer. I feel it is well worth it to spend a couple $100 MAYBE to get them interconnected.
My REIA has someone that knows of a law suit in town against a landlord. Unit had a fire that caused a death and investigation is looking into finding smoke detectors. Now, this is a pretty rare occurrence, but I'd rather have extra effort to interconnect if this were to ever happen to me.
