Review title: Kidde Firex Smoke Alamr PE120
Product review: My landloard replaced my smoke alarm with this model. He had a hard time getting the unit to stop chirping after he installed the battery and hooked it up to the electricity. He finally got it stopped. But the alarm has been chirping, on and off, like there was a problem with the battery again. Not a fan of this unit or the fact that it doesn't have a hush button.
