Product Description

Size: 1 Pack

Amazon.com

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. Two AA batteries are included. 7-year limited warranty. UL listed. --Bree Norlander

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 it’s 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. It is recommended that you place one Carbon Monoxide alarm on every level of the home and one in each sleeping area. 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.

This product was easy to install and seems to be working well so far.
Mr Fixit
Hopefully I will never have to know if it works or not, but feel very comfortable that this is a good product.
Thomas G. Watkins
I like the digital display on this one as it lets me check the highest level for the previous 24 hours.

I bought two of these after another cheaper carbon monoxide detector had alarmed in the middle of the night. I had read some reviews of the other carbon monoxide detector having false alarms and convinced myself it was probably a false alarm but I opened windows to air out the house.

I got these two days ago and they alarmed the first night. I opened the windows and deduced that it was probably my tankless water heater which was recently installed and failed inspection. It is scheduled to be brought up to code this week.

To prove my theory I made sure the central heat was off for a day and we hadn't used the clothes dryer for a few days and I put one of these detectors in the laundry room where the tankless water heater is installed. We have one of those large jacuzzi style baths in the master bathroom (hence the need to have the tankless) and we took a bath last night. When we were done the alarm was going off. I had done some minimal research before doing this test and knew that too high of a level (12,800 ppm) can kill you instantly after just 2 or 3 breaths. I had read that 400+ can be lethal. Wikipedia states 800 ppm will cause dizziness, nausea, and convulsions within 45 min and you will be insensible within 2 hours and 1600 ppm can kill you in 2 hours. So I went downstairs to see what the reading was.

I held my breath and went in. 875ppm is what it read. I called 911 and the firemen came.

My wife, 2 year old, and 2 month old were upstairs and in a room with the windows wide open. They came in and took their readings. They said they are not allowed to work in an environment where the levels are above 30 ppm without respirators. The windows had been open for 15 minutes and they were still getting readings over 70.

Another update.

See recent reviews by others (especially Robert Oppenheim) as well... We just got two of the redesigned ones and indeed they have dropped the remote control feature (good thing) and that would make them deserving of 4 stars, however, they also changed the Peak Level recording, automatically deleting it every 24 hours--that's a bad thing for several reasons and leaves my rating at 3 stars:

1) The peak level resetting should be under user control.

2) One wants to know if, say, during the past week, there was an excessively high reading. Given how it now works, you cannot find that out!

A 24-hour automatic clearing of a bad reading hides potentially dangerous, even lethal situations. (Unless one becomes obsessive about checking this every day!) In this day and age, they really should have a small memory and track days and peak levels!

Here are some other updates--and First Alert deserves credit for listening to some of the critiques.

1) The manual, well it is really a pamphlet, is more readable now.

2) The warranty has been upped to 7 years.

3) They greatly improved the packaging.

Alas, the way the unit is designed means it still wobbles on a nightstand or bureau; the battery cover still doesn't work very well; the CO level still shows up only if one presses the button (and that's a tricky press); the battery symbol still suggests that one is on battery power--they really need a dual indicator for that. In fact, it would be better if you had to press to get the battery level, but that the current CO level would always be displayed. (It's now the reverse.)

Unfortunately, there's another problem. The darn thing glows in the dark and lights up an entire room.

A short video to show the detector in use. I don't subject it to any test fumes in this video.

I ordered and received this item timely from Amazon. The product was well packaged and the directions for use were easy to follow. The product is nicely constructed, easy to use, and seems to work well. I like the fact I can push one of the buttons located on the front of the unit to see if the unit has picked up any CO levels from the area it is located. It is designed to plug into a wall electrical outlet and also has a battery backup. The unit is small and appears out of the way when it is plugged in and being used. So far, the two units I bought are working well so I give this product a rating of 5 stars.

Update: Jan. 14, 2011 - I have now owned two of these devices for over two years and each one is still working just fine. I have had to replace the back up battery on each just once a year, which is fairly standard, so the devices seem to be well built and last.

Here are my first impressions and what I liked about the First Alert C0615 device:

1) This unit comes with two Energizer E91 batteries. Yes, batteries are included with this product). After inserting the batteries and plugging this into the wall outlet in the bedroom, I saw a battery meter flash. It showed the battery had full power.

2) The battery door is on the front of the unit. I like this design because you can have access to the battery compartment while leaving the unit plugged into wall. Also, I was able to open the battery door easily with one finger.

3) I like the display button. When pressed, the unit will show you the highest carbon monoxide level recorded. This is something I plan to monitor often.

4) Green light vs Red light. When I plugged it in, the light is green. Should the device ever detect unsafe levels of CO, the light will turn red and the audible alarm will go off. While I hope to never see the red light, it is reassuring to see the green light and know the room is safe.

What you might like to know about this product:

1) I recommend that you open the packaging from the bottom. I could not separate the plastic packaging at the top. However, it easily opened at the bottom, and continued to open all the way along the sides - up to the top, where I could no longer separate the plastic seal.

2) All CO monitors that I've researched intentionally stop functioning after 5-7 years (for your safety). This is due to the life of the CO sensors. I've owned KIDDE brand and now this First Alert brand, and they all expire. Replacing these devices after 7 years is piece of mind to ensure you always have a functioning CO sensor that will accurately detect carbon monixide.
