Smoke Alarm Has Bad Battery
Hard wired smoke alarms have either 2 AA/AAA batteries or a 9 volt battery. (A battery within your smoke alarm should last at least 12 months) The battery within is beeping because it is getting low and warning you to replace the battery. So the chirping noise means the battery needs to be replaced ASAP. The battery acts as a backup if the power in your home goes out.
