This carbon monoxide alarm is for you if:
● You want the convenience of simply plugging in your alarm, with the added protection of battery backup in case of power outage.
● You would like to easily view the carbon monoxide (CO) levels in your home.
This Alarm can be plugged directly into a wall outlet located close to the floor.
If you are going to use your Alarm as a direct plug into an outlet that is mounted horizontally (sideways), you may want to rotate the adapter 90 Degrees, as follows:
Installation tips for power cord models: The power cord option provides more flexibility in mounting locations and allows the Alarm to be easily installed at or above eye level. NOTE: If you mount the Alarm high on a wall, make sure it is at least 4 inches (102 mm) down from the ceiling. Any higher than this, it will be in "dead air" space and carbon monoxide may not reach the sensor. NOTE: Do not cover the Alarm with a curtain. To install for a wall-mount, you will need to pull out the removable adapter and power cord, as follows:

The FAS-170543 CM Alarm with Battery Backup & Backlit Digital Display replaces a much older CM Alarm by another manufacturer. The new CM Alarm is more responsive and gives my family added security. The design is more appealing to my wife, since it matches the Programmable Thermostat design.

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:"
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.
