I was doing some drywall work and while sanding my CO alarm's went off. The alarm is on the second floor and it iis connected to the one on the first floor and basement. The alarm that went off on the second floor where I was doing the work I took out of service becase it would not stop alarming. Now the two downstairs are going through batterys in a week.
Should I replace all three alarms? If so do I need to replace just the alarm or do I have to replace the hard wiring also?
Should I just replace the one on the second floor? Any suggestions?
