Product Description

Product Description

The FIRST ALERT CO615 dual power carbon monoxide plug in alarm alerts you to dangerous carbon monoxide. This carbon monoxide detector operates on a dual power system with battery backup for continuous monitoring, even in the event of a power outage. The backlit digital screen tells you at a glance what the carbon monoxide and power Levels Are. The Co monitor also features a convenient test and silence button and an end of life timer that lets you know when it is time to replace the unit.*ensure the outlet has power.*the battery is for back up only and is not intended to power the alarm for an Extended period of time in the absence of AC. *the alarm will light up the display briefly to indicate the unit is receiving power. *press and hold test button to ensure activation. 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

One carbon monoxide alarm, two AA batteries, and user's manual.

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.Later, we compared what their professional monitor said to what the my 2nd First Alert Carbon monoxide detector was reading (remember I bought two of these). Their reading matched exactly what this unit displayed. So you can trust these devices.Please trust your device. Thats what you bought it for. Call 911. Open windows or get out of there. The long term affects of Carbon Monoxide exposure can cause heart problems, learning disabilities, and many other terrible things. I am now worried about what this has been doing to my family over the last 4 months since the water heater was installed. Like I said I have a 2 month old....I have posted a picture of the unit reading the max value from last night.
