Kidde i12060 / i12060A: age, expiry and what replaces it

Also printed as: i12060A

Quick answer

A hardwired ionization smoke alarm from Kidde with a front-loading 9-volt backup battery. If yours is ten years past the date code on its back, it is due for replacement. Kidde sells a plug adapter (20-9003) so a newer Kidde alarm can use the wiring plug already in your ceiling.
