smoke detector buzzing
Hello all, had a slight flooding in my house where the upstairs tub over filled and it leak downstairs on to the ceiling where my smoke detector is installed. now I hear a constant buzzing. this happened a couple of days ago. I pulled the battery out but it still buzzes. the detector is hot wired with a battery back up. I'm going to replace the detector, but is there anything else I need to be concern about? thanks.
