Title: Wake Up! - Wake Up! - No fire, but it's 3AM! - Wake Up!
Review: I too had these units go off all over our house at 3AM and then again a minute later. I ran around and found one unit with a blinking green light, so I pressed the test button and it didn't sound off again ..... until the *next* morning at 5AM. I again pressed the test button and went back to bed. Later that day I replaced the battery (which is still good, by the way). It hasn't sounded off again for a couple of days, but now I'm skittish in the wee morning hours. Get a different detector.
Is the review positive or negative?
