Customer Questions & Answers

Is the date on the back of these devices the date of manufacture or the date of expiration

I moved into this home on April 2014. The home was built in 2007-2008. I had a false alarm triggered by 1 of the 6 detectors featured here - yesterday. A friend of mine who is also a FF suggested that I simply replace the device instead of cleaning/vacuuming it. However, the date on the back of the detector reads, "2013 Nov 05". I would be surprised if the previous owner changed all the detectors last fall but if it is this new I am hesitant to have to replace this hardwired device as false alarms to happen for a number of reasons. Any feedback is appreciated.

those dates on the back are the manufacture date.

in changing=== the alarms wires do you have to turn off the power

in changing=== the alarms wires do you have to turn off the power
Asked by: marvin
Hello Marvin. Yes. If you are working with the wiring in the ceiling, then you will want to turn off the circuit breaker first as you will be working with 120VAC wiring. If you are not sure of what you are doing or if you have questions, the safest way is to get a licensed electrician to do the wiring. If you are just changing out the alarms, you usually don't have to work with the wiring. You just unplug the old alarm and the new alarm will plug into the old plug. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

Disconnect one alarm unit

I currently have six interconnected smoke alarms installed. One of them repeatedly gives the low battery indication (chirping) even with new batteries. Can I remove or disconnect this one unit without compromising the performance of the other alarms?
Asked by: Luke
Yes, you can remove or disconnect a unit and still keep the integrity of the system. I would recommend however, that you replace the defective unit as soon as possible.

3 wires or 2?

Do these units have 3 wires or 2? In the picture it shows 3 wires with no connectors, a red, a black, and a white. The text description says 2 wires. Thats a bit confusing. I am replacing 6 existing hardwired units from a different brand called USI that have 3 wires, a black, a white, and a yellow. I'm going to have to splice the connectors off the old detectors and onto these new ones but want to make sure that these have 3 wires as well. Thanks.
Asked by: Daniel
These units have a THREE prong connector into which an assumed *three* hard wired prong provider in the ceiling are expected to connect. Because of the hassle of dismounting the unit(s) when the battery requires replacement (about once a year), the use of the plug in connector could be an advantage IF your three wires can be assembled into an appropriate provider of the required three prongs. In any event, YES these are in fact three wire units.

If you need 6 smoke alarms this is a good cost/item deal. easy to install, they didn't exactly fit the same wiring or connector as my old units but were easy enough to change out. The only real downside to these units is that the battery cover is on the back side of the unit. You have to twist out the unit from the ceiling and remove the wires when replacing the battery. If that's not a problem for you then I would recommend them. My picture shows the backside of the alarm so that you can see the battery compartment.

I bought this 6 pack to replace my existing alarms that were hard wired in when we built our house 15 years ago. This was an easy swap. Replacement of all six took about 20 minutes.

Rated 5 out of 5 by from 6 detector replacement was easy Compatible with the drywall mounts and plugs. Rewired with the new plugs that came with just because, well they were "NEW". Shipped on time just like they said and had everything done in under 2 hours. They also came with 9V batteries if you don't have any. China brand batteries so they will get changed out this fall with daylight saving time hits.

Rated 1 out of 5 by from False alarms galore! Can't get enough of replacing 9V batteries? Are you dying to be jolted awake every time someone lights a cigarette in Bangladesh? Then the Kidde 12040 is the smoke detector for you! Equipped with Kidde's proprietary SMD (single molecule detection) technology, a simple speck of dust or a 0.003 degree change in room temperature will bring these babies to life, scaring all your pets and costing you hours of shut-eye. And when the battery is exhausted from all these false alarms, Kidde's patented "nano-chirp" alert system will completely prevent your brain from using triangulation to narrow down which detector is chirping, ensuring hours of fun detective work! Before long, you too will be bringing your Kidde 12040s outside to smash them with a sledgehammer. Fun for the whole family!

The base did not match the existing Kidde smoke detectors they were replacing. I would have thought that they would standardize their bases. That is not the case. Also, the holes on the new bases did not quite line up with the J-box holes. Could have been designed better. It worked, but the screws were pressed firmly against the outside edges of the base hole cutouts. No issues with the smoke detector itself. I am sure it will do a fine job slowly draining my 9v batteries as it waits for what I hope never happens.

Rated 4 out of 5 by from Fast shipping, easy installation Ordered from the store on a Sunday afternoon, and received it on Tuesday afternoon. Fastest shipment I ever experienced. Detectors used newer version of pigtail than my 12 year old Kidde system, but changeover was a simple matter, that took less than five minutes per unit. This revision of my former Kidde is a good one. Hush feature is more positive, alarm phasing to other units is much swifter. Alarm is much more sensitive to low levels of smoke, giving greater confidence. My only complaint is with the limited holes in mounting bezel, and that they were scored, but not pre punched! If I were an installer, I would be extremely frustrated with this totally unnecessary nuisance. Battery change is a bit more involved, but not difficult. Units are bright white, and more attractive than many detection products.

My previous 6 Kidde smoke detectors were 10 yrs. old and started chirping despite battery changes. I called Kidde's customer service and they recommended these as replacements. These arrived the next day and were easy to swap out from the old ones, fitting perfectly on the existing rings and plug receptacle. I've had them for several weeks and they work just fine. No more chirping!
