We changed all the batteries. 2 have stopped chirping but 1 is still chirping about every 30 seconds and the other beeps every minute or so. Help, I'm going crazy and my dog won't stop barking at the chirps. Thanks, Liz</em><br /><br /> <strong style="font-weight: bold;">Latest post, made on 2009-11-07 07:53:52</strong><br /> we have 5 smoke alarms 1 started chirping, replaced all batteries still 1 chirps need help 2204532#2971552 Sat, 07 Nov 2009 07:53:52 -0500
