I believe i need to replace my kidde smoke and carbon monoxide alarm.( nighthawk model # kn-cosm-1b) It started going off intermittently so I detached it from the ceiling. Their is a white label that says i should replace on 1/2017 (I assume that is the detector and not just the battery...is that correct ?) Also this detector uses a 9v battery along with 3 wires that are connected to it that uses a special 3 prong connector. In order to replace my old one I would like to find one that uses the same connectors to make it easier. Let me know
Asked by: duane
Hello Duane. Your KN-COSM-IB has a 7 year lifespan from first use. After 7 years of use, you should replace the alarm. This alarm you have chosen is NOT a hardwired alarm but any of our hardwired smoke and carbon monoxide alarms can be used to replace your alarms and will have the same plug and the same bracket. This will include the KN-COSM-IBA, Model # KN COSM IBA, Internet #205711626, Store SKU #1000535870;; the KN-COPE-IC, Model # KN-COPE-I, Internet #202188174, Store SKU #714543, Store SO SKU #198092;; and the I12010SCO, Model # 21010408-N, Internet #205465829, Store SKU #1000535877. However, there is an unusual recall on the model KN-COSM-IB made between June 1, 2004 and December 31, 2010. The alarm can fail to continue to chirp when it reaches its seven year end of life if the batteries are replaced, leading consumers to believe it is still working. This poses a risk of consumers not being alerted to a fire or CO incident in their home. Consumers should immediately stop using the recalled alarms and contact Kidde directly for either a free replacement alarm or a discount on a new alarm based on the date of manufacturing. If your alarm falls within this recall, please call 1-855-239-0490 from 8 am to 5 pm Eastern Standard Time Monday through Friday or go to https://inmarmarketaction.com/kidde217/kidde-us-entry/ .

Are the batteries user replaceable after the 10 year expected life?

Are the batteries user replaceable after the 10 year expected life?
Asked by: mclark
Hello Mclark. No. The alarm itself only has a 10 year lifespan and has to be replaced after 10 years. The battery is built onto the circuit board of the alarm and there is no access to the battery. After 10 years, dispose of the alarm and purchase a new one. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

Installed them in the bed room and kitchen. The one originally installed in bedroom started to gave fake fire alarms after 6 months (2~3 times a week.). I tried to switch the alarms. The alarm continued to give fake fire alarms in the kitchen; While the other one does just fine in the bed room. So, I'm pretty sure that the alarm did not work. It's very annoying when it happens in midnight.

My contractor installed this alarm, and within the past two months I have had to replace twice due to false alarms. I will again be returning, third time, today and purchase another brand. I definitely would NOT recommend unless you want to be awaken in the middle of the night.

Rated 3 out of 5 by from A couple pros, but also a lot of cons It's a smoke detector. Nothing fancy. Simple to hang - even though it came with no instructions or hardware. It costs about two or three times more than a standard detector. I guess if the battery really last ten years, that's good, but then you have to toss the detector out and buy a new one. Very wasteful and kind of a scam. I bought it so that my tenants can't pull the batteries out to power their TV remote control or to silence the beeping of a dying battery. Now I'm afraid though that they (not knowing any better) will just rip the whole thing off the ceiling attempting to get at the sealed battery. Can't decide if I'll buy any more of them. Wish there was an expiration date on the package. How do I know if that ten year battery hasn't been sitting on the shelf for nine years??

Rated 2 out of 5 by from Does not last long I installed this in our Master bedroom and it was great at first, however after only a few months of being installed it started alarming for no reason in the middle of the night. Being that the unit is sealed there is no way to replace the battery. I bought another one thinking maybe this one was just defective, however the new one did the same thing.

Rated 1 out of 5 by from defective Got it install the next evening the fire alert started going off and there was no fire, no excessive heat, no nothing. Hit the hush button, it kept going off for over an hour. I pulled it down but it kept going off eventually even after looking through all the instruction trying everything until it stopped. Going back to batteries.

Last night I had my fourth false fire alarm, all happening between 1-3am. I'm now going to give up and replace them all.

My husband has spent over one-half hour trying to just get the cover off so he can install the mounting bracket. Absolutely ridiculous. As it's a holiday, I told him to bring it to the local fire station to see if they can do it.
