Product Description

Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air.

The First Alert CO615 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. Installation is as simple as plugging it in to any wall outlet. Its easy-to-read backlit digital LED display gives you a clear read-out of current CO concentrations in parts per million. The alarm includes a battery back-up giving you peace of mind in a power outage. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. An audible and visual low battery signal alerts you to replace the battery and an indicator alerts you when a battery has been removed. An end-of-life alarm of three chirps alerts you to replace the unit. One 9-volt battery is included. 5-year limited warranty. UL listed. --Bree Norlander

Customer Reviews:

  • Hopefully we never have to hear it's alarm
    This unit was very easy to install. All we did was plug it in. There is no way for me to give this a full 5 star rating since the alarm has not been needed yet. Hopefully it stay that way....more info
  • Great Product
    I was using an older First Alert battery product and kept having false alarms. This unit is so much better than my old one and was easy to install and very easy to operate. ...more info
  • First Alert Carbon Monoxide sensor #00615
    Item was just as described. Easy to set up, test button worked, sensor is not bad looking. Can't test reliabilty of its detection sensitivity, so this is always a question. First Alert has a good reputation so I have to rely on that, and hope that a problem never arises.
    I would buy again and would recommend it to others....more info
  • Excellent CO detector
    This monitor does it all. The power cord allows for mounting the detector away from an AC outlet. The display is easy to read and is backlit when activated....more info
  • It's a CO Alarm
    The product appears to work fine. However, I purchased a Kiddy Nite Hawk CO Detector with Digital readout and for some reason, the peak memory level for this product shows about 16PPM while the First Alert Alarm always shows zero.

    At this point neither one of the alarms have gone off so I'm hoping that my family is safe.

  • Plug and play.
    No problems. Appears to be working fine. Great piece of mind having it in the house....more info
  • Carbon Monixxide detector
    The delivery was very fast, and I liked the easy to read digital display so much I ordered a second one to replace another detector that I had that lacked this feature (even though there was nothing wrong with the older unit.) The fact that there is a battery back-up also really sets my mind at ease....more info
  • Simple to Use, Simple to Test, Great Value!
    My old carbon monoxide detectors were a different brand, and they were due for replacement. I trusted the First Alert brand and gave these a try. I bought three of them (one for each level of the house). They work great, they are simple to test periodically, and I was very satisfied with the value for the money. I would recommend these detectors to anybody....more info
  • Peace of Mind
    This is very user friendly and easy to use. Monitors the area and provides information on the level of CO present. I highly recommend at least one on each level of your home....more info
  • Russell Starner
    After the purchase I didn't realize that the best place for the unit in up high. Unfortuately where I live now won't allow many things to be hanging on the walls. The biggest drawback to the unit is the cord that is used to plug the unit into the wall. I do like the battery backup feature. I got the unit for safty purposes. I had no reason to test the unit yet. I hope that I didn't waste money by buying the unit....more info
  • chintzy
    Front latch will not close after you insert batteries. Well, that's helpful. For the price, I expected this to be a better-made item. I don't recommend this item for purchase....more info
  • Seems OK, but have several concerns...
    We bought this to supplement our Kidde Nighthawk CO detectors, the 900-0234 curved model with a 7-year warranty (we didn't want to put all our eggs in one basket!). The First Alert looks to be a fine CO detector.

    Here are some positives:

    1) It has the plug on a wire, so that you can put the detector somewhere other than right in the outlet. That's helpful as outlets can have other adapters in them making it hard to plug it in or be behind something rendering the CO detection harder.

    2) It can be tested or silenced with a remote (hold down the volume or channel button for 5 seconds) (our Tivo remote worked!). (Some of their other products with the remote features have received critical reviews as regular remote operation has set them off!)

    3) Operates on AC with a battery backup (2 AAs)

    4) Batteries ARE included!!

    Here are several negatives:

    1) 5-year warranty unlike the Kidde's 7-year.

    2) A "manual" that's a huge, cumbersome, folded sheet, with small print that's blurry and hard to read. They should supply a magnifying glass with it! This is a major concern as one needs to refer to the text for installation, for operation, to determine what to do under certain conditions, etc.

    3) Yes, one can park the detector on a bookshelf (with the cord going to the outlet), but the detector itself wobbles! The previous Kidde CO detector Nighthawk model--the COPP-3 -- has the plug on a cord feature, along with a nifty slide out stand that makes it stable. (We had good luck with that model, but many did not. Plus, it's an older model, with only a 5-year warranty which is why we went for the 900-0234).

    4) The CO level only shows up if one presses a button. It's a cool blue light, but unlike the Nighthawk's red LED that shows you the current CO level at all times (a reassuring 0), this displays a blank screen with a recessed green light. For some, it could be a plus as it would be less intrusive especially as the Kidde's red LED seems to be much brighter on their latest model.

    5) The detector displays a battery icon when it's plugged into AC and the battery back up is installed! That's unnerving as it makes it seem as if it's running on the battery! Very odd design choice!

    6) The test alarm didn't seem as loud as the Kidde's.

    7) Battery cover is the front of the device, which the manual didn't explain or illustrate, and it doesn't shut well--or rather, it's awkward and you feel as if you're about to break the lightweight plastic parts.

    8) One other issue, which plagues all the CO detectors and many other products on the market, is the infuriating, hard plastic packaging. It's hard to open and I even cut myself on it. There are alternatives that are just as secure but much friendlier to the environment and the customer!

    In comparing the two (Kidde Nighthawk 900-0234 and the First Alert CO615), the advantage clearly goes to the Kidde. It just seems a more professional, better designed, and better thought out product. Part of that is because we're used to the Kidde design and like the red LED, but it also seems more solid (the First Alert has the seemingly fragile/flimsy cover), and has a higher quality, usable manual--it's a real booklet that's more readable and better organized (it also has a bigger font than FA's, but still could be larger)....more info
