My alarm keep going off even after I changed the battery. How can I fix this?


Sounds like it is dirty. You can either try to clean it out using a vacuum or blow it out with a compressor or a can used for blowing dust off computers. If that fails check the electric connection and if that is fine then it needs to be replaced. PS you may want to consult a licensed electrician when doing the electric checking
