BATTERIES NOT AVAILABLE
THE UNIT WILL ALARM WHEN THE BATTERY IS ABOUT ONE YEAR OLD. IT'S PLUGGED INTO 110 VOLTS AND WILL STILL TELL YOU THE BATTERY IS BAD, EVEN WHEN IT HAS POWER. THE ONLY WAY TO SHUT THE THING OFF IS TO UN-PLUG IT. BATTERIES ARE IMPOSSIBLE TO FIND, VERY POOR MANUFACTURE FOLLOW-UP WILL NOT RECOMMEND THIS UNIT TO ANY ONE.

This is the brand the guy from the gas company recommended. It works well and has an easy-to-read display. I am buying another one for another part of my house.

It's OK but didn't work at first
When first plugging the unit in inside the house I had a problem with resetting it and getting the level to read zero (with several attempts). I thought I might have a carbon monoxide in the house at first but took the unit outside and plugged it in in the garage and it reset to zero with no problem. After moving it back inside the house I plugged it in and now it works just fine. I still don't know why it [messed] up at first or mabey if I didn't do something right, but it was very frustrating. The good news is that it appears to work great now.

CO Detector False Alarms
I have had this detector for a few years and it has worked flawlessly. I have always had very low CO readings in my house since it is 75 years old now. Recently, my wife while in the house, was talking on her Cellular Phone, and walked within 5 feet of this detector, and it set off the detector and caused the detector to generate false readings from the radiation that the Cell Phone was producing. She actually saw the display, displaying a series of random numbers, as she was talking on her cellular phone. We also have 900MHz cordless phones in the house and these do not appear to affect the detector.

Every floor of your house should have one!
One reviewer questioned if these really work... YES they do! I had a new furnace installed recently, and the installers made a mistake. Without detectors in the house I might never have known, and my family could have suffered greatly (ie somebody could have become ill or even died!).

We had had them for years and they ALWAYS read 0. When we started seeing it detect CO we knew we had a problem. Occasional low readings (such as near your kitchen on Thanksgiving if you have a gas stove) are ok, but any consistant reading is cause for real concern particularly if it is away from any known source of CO (stove, fireplace, etc).

I strongly reccomend folks place a detector on each occupied level of your home. If something happens you may very well get different readings on different levels (I did).

When selecting a CO detector be sure to pick an electornic one with a digital readout. They cost more, but are well worth it. The only maintenance with a unit like this one is replacing the backup battery. (BTW, a backup battery is a really good idea. Each year many folks die because they used various types of gas heating devices during power outages with inadequate ventalation.) Also, the digital readout will help track down problems envolving lower levels of CO and may give you earlier warning of a malfunctioning heating system.

Finally, this particular unit has an advantage in that it can be placed directly over an outlet, or the included power cord can be used to allow higher wall mounting or placement on a table/shelf/etc. ... Read more

late shipping

chirp chirp chirp
This is not and I repeat is not a good alarm. There is one alarm light and you can hardly tell which one is sounding. It looks as if the specs are lying to me and I hate lies. Also the battery died after 6-8 months. The low battery alert is loud and chirps so anoyingly. I also noticed that the alarm sounds a loud shrieking alarm when it sounds. I will return this alarm. Never again will I trust in First Alert! ... Read more

Lifesaver!
We've had our detector four years, always showed the low reading of zero. Then, in the middle of the night one night it awoke my wife and I to display very high readings of carbon monoxide. We called the fire department which investigated to discover a problem with our furnace. They said if we didn't have it we might have died.

This detector saved our lives!
We had two CO detectors in the home, this one and another brand's battery operated one. The Nighthawk always went off and my parent's always ignored it. Finally, one Sunday, without my parents permission (I was in my 20's), I called the fire department to have them check it out. Our levels were so high that the fire department said that got an instant headache when they walked in. At times our levels were well over 300. Please get one...Co is the SILENT killer.

Works perfectly
I work at a truck shop where noxious fumes can sometimes make you sick. In the office we have this detector and it gives you that extra security in case the carbon monoxide level gets to high. It has gone off a couple of times, and you wouldn't even of known there was a problem otherwise. Basically this product works great, and I just wanted to let everyone know about it. ... Read more

better packaging may save my time in the future
The reason I purchased the First Alert RD1 Radon Detector was because I was trying to sell my house and needed to show that I had done testing. When I received the kit- I found that in order to do a real estate transaction you must do 2 tests. I wasn't aware of this until I opened the packaging. WHich upset me that I had to go back and purchase another one. Also I didnt realize that it was going to take me 21 days to get my test results in. I felt as though that was an over extended time, considering real estate deals can be done within a week. ... Read more
