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.

Worry Free 10-Year Sealed Lithium Battery Smoke and Carbon Monoxide Combination Alarm with Voice Warning is rated 3.9 out of 5 by 81.

No CO2. Temperature was about 68 degrees. Well it certainly is alarming .. but we installed this 6/1/16 and it failed 1/9/17. The label says it was made 2016 Feb 20. The previous one lasted a couple of months longer, but failed while we were on vacation, and my pet sitter had to disable it. It was probably going for hours (my poor pets!!). For $60 a shot, this is not a good product. It gives 3 suggestions if alarm sounds: 1) Operate Test/Hush button. Hush button did not function. 3) Immediately move to fresh air. Fresh air did not make it stop. 2) Call 911. I had no intention of calling 911 for this trash. It says 'For service return to Kidde', and cautions that 'Turning off the alarm is permanent' ... can't imagine trying to return it while it is making that horrible noise. No Toll free number to call .... oh yeah ... it is Made in China. Waste of money. Twice. Shame on me. Save your money. I'd give it zero stars if I could...how can I rely on something to alert me to a problem if it can't be relied on to operate properly. Not even going to try to return it to Home Depot. Straight to the trash.

Great product, works perfect when installed according to "easy instructions". Unit only is activated once it is installed on the supplied bracket, which is the way it should work. Voice Warning works well in test mode. I installed my unit approximately 10 feet from my gas furnace on the unfinished side of my basement for added protection in my basement which is 85% finished. Other area of basement has a Kidde "hardwired" smoke and CO2 combo unit with battery backup!

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.

Dead on purchase. This was a replacement for a 2 year old Kidde P3010-CO, whose battery was low at 1V and chirping about carbon monoxide rather than low battery. I will not buy this brand again

A neighbor installed these for me, because they were on or near the ceiling. They both work OK, we removed the old devices too. So far so good as they are supposed to last for 10 years.
