This year our Firex 120-1182 smoke alarms are periodically going off in the middle of the night. I have changed out the batteries. I have dusted them. 3 of them seem ok. After dusting one, it would go chirp and then I was able to get it to stop. Then about 15 hours later it started chirping again at a quicker interval. Any suggestions?
