I'm using regular edible gummy bears and resin from a craft store.
Just one question here Smoke detectors are battery-powered, and you say yourself you've replaced the battery. So what would the house power have to do with it? That's like turning off your water mains and expecting your bottled-water dispenser to work better afterwards!
Put this one in the trash and get another one installed. Life span of a smoke detector is about ten years anyway.
If you are talking about a 120 volt battery back up smoke detector, it will make the same noise of it fails to obtain power from the home. I would check to see if it is getting 120 volts from the wiring before you buy a new one. If that is the problem the new one will do the same thing.
In Arkansas you may beat your wife on the court house lawn on Sundays .just as long as the stick is mo bigger than your thumb.
Do yourself a favor, the smoke detectors needed to be replaced every 7 years. To save further on headaches, buy the new types which are lithium-ion battery powered smoke detectors, these would last 10 years for the battery, but you would need to replace the detector itself too. I will be replacing my smoke detectors with these new types. You won't have to suffer the chirping anymore at least only once every ten years, just remember to replace the whole thing before ten years have passed. These are available at Home Depot, OSH, Lowe's, yes, even WalMart sells these.
