had 5 installed a year ago. I replaced all batteries yesterday. One of the alarms chirps even though I put in 4 diff new batteries. I put one in and it was ok for about 16 hours and now it started chirping again. Tried 2 more new batteries. Finally gave up and pushed the 13 hour hush button. Am I going to have to have all 5 replaced with another kind of alarm and have to hire the electrician again?
