Why does my First Alert Smoke Alarm keep going off for no reason?

If your First Alert Smoke Alarm is alarming for no apparent reason, it could be due to several factors: * **Dust or dirt in the sensing chamber:** Clean the unit's sensing chamber with a vacuum cleaner, following the unit's instructions. * **Improper location:** Refer to the unit's instructions for recommended and not recommended locations and relocate the unit if necessary. * **Unit malfunctioning:** Consider replacing the detector.
