Hard to find interconnected smoke/CO detectors that are battery powered?
I am due to replace my smoke detectors in my house due to their age and I was interested in getting the newer interconnected types.
However my house is not wired for hardwired smoke detectors and I don’t exactly want to pay an electrician probably well over $1000 to run all those wires so I need battery powered ones as I’ve always had…
But as I’m looking is seems like the major brands (Kidde, First Alert) no longer make battery powered interconnected smoke/CO detectors? Even when a model two is listed on their website, if you try to actually find them for sale, they are discontinued or out of stock everywhere.
There is ONE from First Alert but it’s an app-based smart one that is 2-3X the price of most others and would be quite pricey to outfit my house with.
I do see “secondary” brands (X-Sense, Innolink) which offer them, but I see lots of warnings on here and elsewhere questioning their certification and quality. Plus, at least for some, their instructions make the interconnection seem much less friendly are sometimes are written in poor English.
Is there a reason why the major brands no longer offer such a thing? Will they ever come back?
One further complication: due to building code, is part of a bigger job, a contractor installed a wired interconnect capable Kidde smoke detector in my garage a year or so ago. I was initially looking for something that would connect with that, but since nothing from Kidde is available, as a backup I was wondering about replacing it with another brand.
But it seems that wired interconnected detectors communicate through the wires? And so they wouldn’t communicate with wireless ones elsewhere in the house? Are there are options for AC powered ones that would interconnect wirelessly with battery powdered ones?
