Great deal
One of the smoke detectors in my office died and I needed a replacement. This unit had a good price and I liked the idea of not having to change batteries all the time (twice a year). Got fast shipping and installation was easy. Would buy again.

No more changing batteries all the time
This smoke alarm was very easy to install. It went off a couple times while I was cooking, so I know it works! The hush button is great for when that happens. And best of all, no more low battery beeps and buying batteries. So far, so good!

Peace of mind
Think of not having to change the battery all of the time. Plus, The hush button is great when you are baking

Easy to install, works great
This smoke detector was quite easy to install with two screws. There are no batteries to replace and, when it works, it is loud and effective.

One note: because there are no batteries, you can't take them out if you have smoke ... say you burned something in the kitchen ... so you'll have to deal with the alarm ... or just don't burn your food when you cook :)

May be cheaper at Home Depot...
Great product. It has a "kickstand" so it can be placed on a table or screws so it can be hung on the wall. The digital display is recommended for CO testers. You can change batteries without removing the tester from the wall. A leading consumer testing magazine recommended this one.

I often buy from Amazon because it is easy and usually cheaper. However, I found this item at The Home Depot (reg. 39.99) on clearance for 19.99.

Fine, better-than-basic CO alarm
This is a good, high-quality device, with a clear display. The display is a little smaller and contains a little less than the earlier version of this same detector (of which I own two), which is the only reason I didn't give it 5 stars. But it works well, as best I could test it (using the vent from my gas oven), with a clear, easy-to-read display. The ability to change batteries without dismounting it is a plus. I bought this model (earlier and current versions) because it was highly rated and a good buy according to Consumer Reports, and it lives up to that review.

Placement
Easy to place where ever you like, as it's battery powered and you do not have to plug it in. The one's that plug in I avoid as placement becomes a major inconvenience.

Works as advertised
Product worked exactly as advertised. Very good directions. Well made. Should work for years. I liked the fact that it's battery operated and could put it anywhere.

Decent smoke detector
Picked it up on a discount via a company initiative to ensure everyone had adequate smoke detectors in their homes. It was easy to install and seems reliable.

Satisfied with this smoke detector
Even though there are many, many types of smoke detectors available, there really isn't much choice. Literature on fire safety says to get one that has both the ionization feature and the photoelectric feature. You see many that only have one feature or they combine it with a carbon monoxide detector. Get a smoke detector that focuses on its job. Get a separate carbon monoxide detector and locate it down at your level instead of high on a ceiling.

The alarm is nice and loud, which I need. I wish it could wirelessly activate the other alarms when it goes off. You have to remove the smoke detector to change the battery, but that is very easy to do.

Don't forget to mark on your long term calendar to replace it in 8-10 years. The ionization feature may not work after that.

Smoke alarm
Haven't had occasion to observe its function, except by using the test button. It will do well.

Much easier to set up and better than 'First Alert' dual sensor.
I had purchased the 'First Alert' dual sensor alarm (with remote feature), and it gave me nothing but false alarms, some in the middle of the night! Not so with the Kidde. Plus getting to and installing the 9V battery was much much easier on the Kidde than on the unintuitive 'First Alert'. This Kidde dual sensor alarm is the way to go if you want simplicity, ease of use, and peace of mind. I think I am going to purchase a few more now that I know this model works flawlessly.

kidde dual sensor smoke alarm
The common complaint about the dual sensor alarm is "false alarms".I have had the five alarms installed for three weeks and no "false alarms" and my house has a working wood stove.

Great Detector!
This product works! I recommend this product to all!

Good Combo
These were bought to replace others. Never had any problems. Combo preferred over buying two units for smoke and carbon monoxide.

nice to have around

It was easy to put in the ceiling and easy to put the battery in.
it is good to have because it will hit to birds with one stone, so to speak, by being a smoke detector and a carbon monoxide detector as well.

An Excellent Combo Alarm
Of course, First Alert is known for quality products, but this device is better yet. Very easy to install, easy to maintain (uses double A instead of 9 volt), relatively inexpensive and sounds an alarm shrill enough to wake up my 10 year old dog. Buy it!

Easy and Effecient
Install of the detector was easy and the product is great. Voice alert tells you what kind of alert (either smoke or carbon monoxide). White color blends nicely with the ceiling. My only negative is that you have to twist the detector off of its holder an unplug the wires, in order to replace the battery.

Peace of mind
For those concerned about previous mfr date issues with reviews, my units were manufactured within 45 days of my purchase date -- which is actually extremely reasonable. I'm guessing that wherever these are manufactured, they are taking a boat trip at least once before hitting a warehouse to wait for me to purchase.

I recently replaced my 10 year old BRK detectors around my entire house. I installed the Kidde PI2000 dual sensor detector in each beadroom and a Kidde KN-COSM-IB smoke and carbon dioxide detector in the hallways in the basement, first and second floor hallways.

I researched first alert, brk, and kidde, mostly because I could see them at my local big box hardware store. I chose Kidde becuase it had more features for the wired-in detectors than both first alert and brk. First alert appears to have focused their current lines on battery only units and wireless communications. Brk also had limited options in dual sensors or combo co2 detectors in a wired setting. Since neither first alert or brk could supply both a photo sensor/ion wired unit AND a dual CO2 and smoke wired detector that communicated together, I chose kidde detectors. I wanted them all to communicate and mixing and matching product vendors makes communications between the units impossible.

There are no pretty dual detectors that exist on the market. These are nice and boring and don't draw attention. They have a working hush button. That's a new feature that I appreciate. I haven't ripped one of these off the ceiling once yet to get them to stop their alarms.

I've never done a smoke or co2 test. I'll let the experts run those tests. My only tests are using the test button. But it works as identified and is loud. The voice alarms in the COSM unit is good for the hallways and will supplement the normal alarm well. Children are reported to respond faster to "Fire!, Fire!". I've been know to sleep through my daughter's baby monitor on one of her bad nights... There's no way I'm not going to hear both the voice and the piercing alarms

DIY info:

Since I was replacing an existing AC wired solution, I wanted to continue to have the security of both AC power and battery backup. The best feature by far of this wired in solution is that all detectors are wired to communicate together. If my basement CO2 detector goes off, then the other two CO2 detectors also sound with an alarm and a voice indicator. When any of the smoke detectors trip, all detectors sound, and the hallway units voice alert "Fire!, Fire!". This connection between detectors will ensure that I know in the middle of the night if I have a fire in the basement... My house is well soundproofed between floors.

In replacing the existing brk wired in units with the Kidde detectors, I had to remove the existing collars and wired in "tails" since the existing ones were not compatible with the Kiddes. You can buy an adapter to convert from the BRK style of tail to the Kidde, but I considered that a waste of money. In my house, all of the smoke detectors are on the same electrical circuit and rewiring the tails and installing the detectors was a matter of ensuring the circuit was off, removeing 3 wire nuts, removing the existing tail, then twisting the new tail into the existing leads and putting the wire nuts back on. less than 3 minutes of work.

THe collar was easy to replace. A cordless screwdriver to loosen (not remove) the 2 J-box screws, twist and pull the brk collar off, add the Kidde collar, then tighten the screws.

All in all less than 5 minutes per detector... replaceing 7 detectors took less than an hour of work and I made sure to test each one for communications with the other units.

For the single detector that I have close to the peak of a cathedral ceiling I replaced the nice alkaline 9v that shipped with the PI2000 with an Ultralife Lithium 9v... they are made specifically for smoke detectors and are claimed to at least double the lifespan of a alkaline up to 10 years.... I'll let you know in ten years if its true. In any case I don't expect to have to change that high detector's battery for years now.

Remember that smoke detectors have to be replaced every 10 years.. units that detect CO2 will have to be replaced after 5yrs... its a chemical based sensor.

Good product - kit included everything needed to easily replace older unit

Worked from 2001
I purchased this combo smoke/carbon monoxide detector in 2001 to replace my hard wired smoke detector. It has hung on my wall near my furnace room for over 7 years. I received an "error chirp" last night so I am in the process of replacing the unit. This unit has lasted 7 years and of course, I wish it had lasted 10 years. In the 7 years, it went off about ten times when the house filled with kitchen smoke. The carbon monoxide detector activated once, when my furnace malfunctioned. I never had a fire.

I was suprised to hear some of the complaints of others about the unit malfunctioning. The best thing to do is return it right away! If you are lucky to get a good one, you won't be sorry.

Excellent Smoke/Carbon Monoxide Alarm
This combination alarm has worked perfectly in our home. I have since replaced others with this model.

Great fire alarm
This is a great fire alarm. I have it at the top of the stairs by the bedrooms, and its gone off a few times when I forget to turn the vent on in the kitchen and cooking something with high heat. Other than that, no false alarms. I'm 5' 7", and I love that I can jump up and press the big Silence button when needed instead of trying to find a chair. It chirps loudly when the batteries are low too.

Goes off in the middle of the night
For the second time in a month the alarm has gone into test mode in the middle of the night when we are all asleep!

great product
This product works great and the price wasn't bad either. They came in right on time!

Use them in your office
Great product, Combination Smoke & Carbon Monoxide Alarm I have them in my office and never have to worry about them.

EZ
These smoke detectors are easy to install and the talking feaure is great. They come with battaries and clear instructions. The DVD is more about the life of a fire fighter than fire safety though.
