My first caveat is my husband and I can't hang a picture without help. Look up un-handy and it is our picture.
One if our smoke detectors is chirping. Looking at the directions it appears the backup battery needs replacing. On the unit itself it says to turn off the power first. Does that mean from the breaker box in the garage? We can't find a power button on the unit so I must assume so. That's right. We got this old without ever replacing a battery in a smoke detector. Thanks!
