Hardwired Kidde Nighthawk co/smoke detector chirps every thirty seconds even when it is unplugged--the chirp comes from above the ceiling--in the attic. What is going on with this? How do I stop it from chirping all night?


If the display shows "Lb", the battery is probably low; replace it. If the display shows "Err", push and hold the Peak Level button. Does the display change to "E09"? If so, then you have just been "had" by the grossly under-documented "planned obsolescence feature" called, rather matter-of-factly, "End of Life". This means that ~7 years after first being powered up, the unit will, BY DESIGN, cease to function, forcing you to buy a replacement. Would have been nice of Kidde to include THAT warning on the OUTSIDE of the package. Call their "Hotline" at 1-800-880-6788 and tell them what you think of that policy. If it is still under warranty (5 or 7 years depending on date of manufacture) they should replace it. In any event, buy another one; if they replace your first one you will have twice the protection. Not a bad thing. *Disclaimer: I am not a lawyer, despite the handle. Words to live by: "Every creative act results from a sudden cessation of stupidity." -Edwin H.

I have a KIDDE / NIGHTHAWK Combo Smoke / CO Alarm (Model #KN-COSM-IB). It is "chirping" once every 30 seconds. I understand this is an indication of alarm malfunction. My question is: what do I do about it? The battery has been checked and is not the issue. What now? Thanks.


Normally, that means the battery(s) need changing.. But, hundreds people have had problems with this combo detector, it's hard to predict what it is. But, as I said earlier, "Normally that means the battery(s) need changing." The keyword here is "Normally".Good luck. I hope that solves your problem.

My Nighthawk CO detector is model no KN-COP-HOJ. It has an error code on it. It beeps every 45-60 seconds. I understand that it must be replaced but I tried resetting it and it wont stop beeping. I need to get some sleep. I will repalce this over the weekend. What do i do in the meantime?


If the display just reads "Err", the unit will not detect CO, so you might as well unplug it and remove the battery and get some sleep, but DO replace it as soon as possible. These units, BY DESIGN, cease to function ~7 years after they are first powered up. If it is still under warranty (5 or 7 years depending on date of manufacture.
