I think it’s just another layer of protection.Right! So why hardwire them at all? They work on batteries if there is no power so what do you gain by hardwiring them?

But why? The lithium battery 10 year models last 10 years. No wiring required, big $$ savings. The ones I took out are using some amount of electricity 24x7, also have to be replaced in 10 years and you throw 4 AA batteries in the trash every year. Both cost $45. I don't see how that is efficient.Hardwiring them is overall more efficient if it's not an electrical fire.
