The Honeywell 5800CO is a wireless carbon monoxide detector compatible with and Honeywell wireless security system. Carbon Monoxide (CO) is an odorless, colorless, toxic gas that is the leading cause of accidental poisoning deaths in America and can kill within minutes of exposure. The most common sources of CO fatalities are from heating systems, engine powered tools and charcoal grills. A car idling in an open or closed garage is another common cause of CO related death. Honeywell's 5800CO, when monitored by a wireless security system, can protect you, your family and your pets from the danders of carbon monoxide.

The 5800CO detector uses electrochemical detection technology. Electrochemical detectors take the most accurate measures of CO levels over time and are designed to sound a warning alarm well before fatal levels of carbon monoxide gas are present. If a CO alarm is received at the central monitoring station and no one responds to the following phone call, medical responders will be dispatched to the property to check on everyone located inside.

The National Fire Protection Agency (NFPA) recommends installing a 5800CO detector within 10' of all sleeping areas, inside any bedroom that contains a fuel burning appliance, on every floor of a home or business and in the vicinity of all flame-fueled appliances (but further than 10' from appliance). The 5800CO should be mounted on the wall at least as high as a light switch and 6" from any ceiling or wall if mounted on a wall. If mounted on a ceiling, the carbon monoxide detector must be further than 12" from any wall. Also make sure not to install the 5800CO near any air vents or within reach of children of pets.

Many states and local municipalities are now requiring carbon monoxide detectors to be installed in homes. Carbon monoxide protection was upgraded in the 2005 NFPA 720 guide from a recommended practice to an installation standard. We recommend checking with your local Authority Having Jurisdiction (AHJ) to see if carbon monoxide detectors are required in your area.

The Honeywell 5800CO is a 345 MHz wireless carbon monoxide (CO) sensor. The device was built with the LYNX Touch Panels in mind, but it will also work great with the Honeywell Lyric, Honeywell LYNX Plus, a Honeywell VISTA System with an added 345 MHz wireless receiver, the 2GIG Wireless Panels, and the 345 MHz Qolsys IQ Panel 2 Plus. This is an extremely versatile sensor, and it makes for a great addition to any compatible security system. We give it a 5 Star rating.

Adding a CO detector to your home or business can prove to be life-saving. Hundreds of people die every year in the United States alone due to carbon monoxide poisoning. The gas is both odorless and tasteless, and it often isn't discovered until it's too late. The best way to prevent loss of life due to a CO outbreak is with a reliable CO detector like the Honeywell 5800CO. We recommend having at least one CO detector on each floor of your home or business.

The downsides to the 5800CO are relatively minor. Like all CO detectors, the 5800CO has a limited product life. In this case, the sensor is good for ten (10) years. That's pretty long for a CO detector, and end of product life is something you will have to deal with on pretty much any device. The device uses a lithium CR123A battery, and you will likely need to replace it at least once before the end of life is reached. Also keep in mind that some users may prefer using combination devices, such as the 5800COMBO or the SiXCOMBO instead of just a standalone CO detector like the 5800CO.

The Honeywell 5800CO is a versatile and reliable 345 MHz CO detector that makes a nice addition to any compatible system. It gets 5 Stars from Alarm Grid.

Good: Life-Saving, Versatile, Easy to Install

Bad: Limited Product Life, Battery Will Require Replacing, Some Users Might Prefer a "Combo" Sensor

Bottom Line: 5 Stars

Hi Masha, Life expectancy on any of the older 5800CO's (2017 or older) was 6 years. Now 2018 or newer 5800CO's life expectancy is 10 years from manufacture date. That should be reflected on the "replace by" date.
The life expectancy for the 5800CO, made before 2017, is 6 years as shown in the picture you've shared. The 5800COs made after 2017 have a 10 year life expectancy.
In my current device there is Replace By date along with production date I guess. I wonder what will be a replace by date for the obe ordered from you store. Thx!
Thanks @dylanandriano:disqus
The ZCOMBO will not alert the central station since it is a zwave device.
I was browsing more of what I can do with Z-Wave today and I see that FirstAlert has come up with a Z-Wave CO/Smoke detector, their model number is "ZCOMBO" - Obviously this will have functionality with the Lyric, but will it be monitored by the Central Station?
Yes, this is the recommend device for carbon monoxide detection when using a Lyric system. We can certainly monitor a system using this detector.
So I know I've already asked about the Firefighter with the Nest Protect for the purpose of fire monitoring (not guaranteed but theoretically should work).. but I know the Firefighter only monitors for fire tones and they don't make a Carbon Monoxide variant. It also looks like Honeywell doesn't [yet] make a SIX module for carbon monoxide.. will this module community with Lyric? And further, does Lyric and/or your monitoring centre have the capability to monitor for carbon monoxide alarms?
