Is this unit compatible with the FireX model that was discontinued and Kidde bought out?

I need to replace a FireX unit tied to four other alarms Model FADCM 12000 series
Asked by: YBOB
Hello. In reference to your question, there are a number of issues here at work. First issue is that the Model FADCM 12000 series made between June 1st, 2007 and February 1st, 2008 were recalled, along with other FireX smoke and carbon monoxide alarms made within this date. If your 12000 alarm falls within this recall, please go through your house and make a complete list of all of your alarms and each of their models and dates of manufacturing and please call 888-879-3906 and they can help you with replacements. The second issue is that the alarm you chose, the Intelligent Battery Operated Combination Smoke and Carbon Monoxide Alarm, is battery only and is not hardwired and does not interconnect. The third issue is that the older FireX smoke alarms, the ones that worked with the 12000 series, will not interconnect properly with our current alarms and will not have the same plugs or the same bracket. You will need to replace all of the alarms that are interconnect at the same time. You will need to take down all of the older alarms that are interconnected together first before putting up any new alarms. You will need to change out the wiring harness plugs and mounting brackets and for that, you will probably need a licensed electrician to rewire at each location. If you have any questions about this, you can call us at 1-800-880-6788. Thank you for your interest.

How many detectors can I have interlocked to go off together ? I need 4 and two 2 packs would do it.

Asked by: john
Hello John. Code will allow up to 12 alarms interconnected by any means, so 12. However, this is not an interconnected alarm. If you wish an interconnected smoke and carbon monoxide alarm, you will either need one of our hardwired alarms and have the alarms connected on the same three wire circuit or you would need all of the alarms to be the KN-COSM-B-RF, Model # 21010625, Internet #205132306, Store SKU #1000046182 or it is available as a 3-pack as Model # 21010625, Internet #205133645.

where on a wall do you place the dual alarm

where on a wall do you place the dual alarm
Asked by: Dispatcher
Hello Dispatcher. Carbon monoxide is the same weight as air and mixes freely with the air and can be measured at any height. Smoke rises and pools on the ceiling and has to be measured from up high. So this alarm should go on the ceiling or on the wall within a foot of the ceiling. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

i replaced battery like it said and it still keeps chirping

how do I get it to stop chirping
Asked by: jamie
Hello Jaime. Make sure you are using new Kidde batteries or new Energizer model E91 batteries with a good use-by date of at LEAST 2022 or beyond. Due to a design change in the Duracell AA alkaline battery, the battery is longer compatible with this alarm. Make sure the batteries are being inserted properly with the middle battery opposite of the other two. If this doesn't fix the problem, call us at Kidde Product Support at 1-800-880-6788 with the alarm and batteries in hand and we can troubleshoot with you from there and see what we can do to help you.

Intelligent Battery Operated Combination Smoke and Carbon Monoxide Alarm (2-Pack) is rated 4.5 out of 5 by 167.
Rated 5 out of 5 by from Excellent product My last one lasted as long as it should have, something like 8 or 10 years. And then started chirping. Very pleased with the new alarm. Tested it and it worked fine. The best part is, I was able to pop off the old Kidde alarm and pop on the new one without having to install the base, saving me some difficulty.

Rated 5 out of 5 by from 7 yr lifespan, worth price mine just went out last week, after 7 years of faithful service, with no malfunctions along the way. Kiddie makes a great detector, and they have never let me down. This is a great buy, but they do have an even better model out now. This time around, I will be upgrading to the li-ion battery version with a 10 year lifespan ... that's three extra years of expected life, and no batteries to change, plus you get to keep all the same features. And at about $10-$15 more than the standard AAA version, the "higher" price really just buys all those AAA's that you won't need to install... saving you time, and putting less batteries in a landfill!!
