Just so, are combo smoke and carbon monoxide detectors good?
Types of Smoke and Carbon Monoxide Detectors
Few combination detectors are effective at detecting carbon monoxide, smoldering fires, and flaming fires, which is why we recommend that consumers use a combination of detectors in their homes for complete protection.
Hereof, can you get a combined smoke and carbon monoxide alarm?
Combined Smoke & CO Alarms
Carbon Monoxide alarms warn occupants about any presence of carbon monoxide gas, which is known as the silent killer. The combination alarms in this section detect both of these dangers, smoke and carbon monoxide, to protect lives with the minimum of space taken up by detectors.
Do you need carbon monoxide detector if no gas?
Conclusion on Installing Carbon Monoxide Detectors Even if You Don’t Have Gas Appliances. Even if your property doesn’t have any gas appliances, it’s still a good idea to have CO detectors installed. You never know if someone who is unaware will bring a gas stove or other small appliance near your home.
Why carbon monoxide (CO) alarms don’t need to be installed near the floor. There’s a myth that carbon monoxide alarms should be installed lower on the wall because carbon monoxide is heavier than air. In fact, carbon monoxide is slightly lighter than air and diffuses evenly throughout the room.
Other possible clues of a carbon monoxide leak include:
- black, sooty marks on the front covers of gas fires.
- sooty or yellow/brown stains on or around boilers, stoves or fires.
- smoke building up in rooms because of a faulty flue.
- yellow instead of blue flames coming from gas appliances.
- pilot lights frequently blowing out.
Probably more than you think! According to the National Fire Protection Association (NFPA), you should install smoke detectors on every floor of your home, in each bedroom, outside of sleeping areas, and in hallways. The NFPA suggests a maximum distance of 30 feet between each smoke detector.
There are three types of smoke alarms, ionization, photoelectric and a combination of the two which is commonly called a “dual” detector.
Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance.
First Alert has better features than the Kidde because of the alarm system with a verbal warning of the threat.
Battery-operated units are much simpler to install and will not fail in a power outage. Plug-ins with battery backups are readily available, but given that gases rise, the standard placement of electrical outlets (near the floor) makes them imperfect receptacles for CO detectors.
