Reviewer: Charles Medchill
I had been away from home for a short time. When arriving home I could hear the CO alarm, after checking the area I determined that the unit was at fault. I ordered a new CO5120BN and an additional as a spare. The replacement arrived in less than a week allowing me to solve he problem. It was the exact unit I needed so no change of wiring was required. Thanks First Alert for the excellent service.

Replaced Smoke/CO with CO only due to builders error, within 5 of stove. CO needed there for BR door. Would have been easier if base plate had been the same for all hardwired models.

Before visiting the site after our carbon monoxide detector failed, I wasn't exactly sure what I would be looking for. The site was very well organized and easy to find our exact model to order. Product works well, easy to install, no complaints whatsoever.

The items came in when promised and work great. The new ones replaced units that were 14 years old and just began to falter. Obviously you make a great product.

Reviewer: Dianne Hendrigan
We moved into a brand new home 7 years ago and the builder had installed this carbon monoxide detector. As you would expect, it's now time for them to be replaced and we were so pleased with this product we decided to order the same detector. You can't go wrong with this product.

The internet picture showed a c2010 smoke and carbon alarm. Thats what i ordered. your description was in error. I returned the co5120bn to you. Now you are charging me a restocking fee for your own error. credit my account for the 3.80.

Customer Service Response:
We do not carry a C2010 smoke and carbon alarm and never have. We looked into your order and you did order a CO5120BN which is what we sent you. If you would like to call us to discuss the restock fee please call 847-991-7190. Thank you.

Q: How do I get my carbon monoxide alarm to stop chirping?

A: If your carbon monoxide alarm keeps chirping, the battery may be low or weak. On First Alert carbon monoxide detectors, check to see if the battery light is yellow or green. If the alarm is chirping and the light is yellow, it means the battery is low. The way to get a carbon monoxide alarm to stop chirping is to replace the battery.

---

Q: Where should I install carbon monoxide alarms? What is proper carbon monoxide alarm placement?

A: It is very important to install carbon monoxide alarms near or in each separate sleeping area. Many states now require that a carbon monoxide alarm is placed in each bedroom. For added protection, placement of an additional carbon monoxide alarm at least 15-20 feet away from the furnace or fuel burning heat sources is recommended. Also, install carbon monoxide alarms at least 10 feet from sources of humidity like bathrooms and showers. In two story houses, install one carbon monoxide alarm on each level of the home. If you have a basement, carbon monoxide alarm placement is recommended at the top of the basement stairs.

---

Q: Is there anywhere I shouldn't install carbon monoxide alarms?

A: Do not install carbon monoxide alarms in garages, kitchens, furnace rooms, or in any extremely dusty, dirty, humid, or greasy areas. Do not install alarms in direct sunlight, or areas subjected to temperature extremes. These include unconditioned crawl spaces, unfinished attics, un-insulated or poorly insulated ceilings, and porches. Carbon monoxide alarms should not be installed in outlets covered by curtains or other obstructions. Do not install in turbulent air-near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows. Blowing air may prevent carbon monoxide from reaching the CO sensors.

---

Q: How many carbon monoxide alarms should I have in my home?

A: So how many carbon monoxide alarms should you have in your home? The National Fire Protection Association (NFPA) recommends that you should have a carbon monoxide alarm centrally located outside of each separate sleeping area in the immediate vicinity of the bedroom. For added protection, you should have additional carbon monoxide alarms in each separate bedroom and on every level of your house, including the basement. Some states now require that you have a carbon monoxide alarm in each bedroom of the house. If you install only one carbon monoxide alarm in your home, place it near or in your bedroom.

---

Q: What is the proper way to do a carbon monoxide alarm test?

A: The following procedure is the proper way to do a carbon monoxide alarm test - Press and hold the Test Button on the front of the alarm until the alarm sounds. Be sure you hold the button down long enough; it can take up to 20 seconds for the alarm to respond to the test.

---

Q: Is it a false alarm when my carbon monoxide alarm sounds and there doesn't seem to be a problem?

A: A carbon monoxide alarm false alarm should not occur if your alarm is in working order. Remember, carbon monoxide is an odorless, colorless gas. If your carbon monoxide alarm went off, it detected potentially harmful amounts of carbon monoxide. After the professionals have evaluated the situation, make sure no one has any symptoms of carbon monoxide poisoning.

Here are a few situations that may cause a carbon monoxide alarm "false alarm:"

• The carbon monoxide alarm needs to be relocated. Carbon monoxide alarms should be located 15-20 feet away from all fossil fuel burning sources like furnaces and stoves. Alarms should be located 10 feet away from sources of humidity like showers.
• Fossil fuel burning appliances may not be burning fuel completely. Check pilot lights/flames for blue color. Appearance of yellow or orange flames indicates incomplete combustion-a source of carbon monoxide.

---

Q: Will carbon monoxide alarms detect explosive gas leaks?

A: No, a single function carbon monoxide alarm reacts to carbon monoxide only. To detect explosive gas, you need an explosive gas detector. Different kinds of explosive gas can be detected and it is recommended that any home that utilizes natural or propane gas have at least one explosive gas leak detector.
