I am offering 2 smoke detectors to anyone who would like them. I recently installed the wired-in type and no longer need these. They are in good working order as far as I know, and come with the mounting brackets and the batteries are still in them. If you don’t have a working smoke detector for whatever reason, please take these just to be safe. Even if you plan to get something else soon, you never know when you will need one. E-mail if interested.
