What Is Carbon Monoxide

Kidde Hardwired Smoke and Carbon Monoxide Detector with Battery Backup and Voice Alarm Installation

Carbon Monoxide is a natural by-product of burning fossil fuels for home cooking and heating. Exposure is usually minimal and remains within acceptable safety standards.

But, breathing-in excessive amounts of this toxic gas can make us feel unwell. And, exposure to high enough levels can prove fatal.

In fact, the Centers for Disease Control and Prevention estimates that each year about 400 Americans die from CO poisoning, and 4,000 more are hospitalized due to exposure to this highly poisonous gas . The symptoms of CO poisoning include headaches, nausea, dizziness, tiredness and confusion, stomach pain and shortness of breath. But, long term exposure can be much worse.

Types Of Smoke Detectors

Smoke detectors come in two main types: hard-wired units and battery-operated detectors.

Hard-wired Smoke Detector

Hard-wired smoke detectors need to be connected to your homes AC electrical system. These types of detectors usually require professional installation to make sure that they are installed properly. A hard-wired smoke detector is extremely reliable but it may not work during a power outage.

Some hard-wired smoke detectors may come with a backup battery such as the Kidde 21007624. If you have an old house, you may have to check its wiring before installing a hard-wired smoke detector.

Battery-operated Smoke Detector

Battery-operated smoke detectors are quick and easy to install and there is no need to worry about hard-wiring the unit. These types of detectors either come with 2 AA batteries, a 9-volt alkaline battery that lasts up to 1-year, or a long-lasting 9-volt battery that lasts up to 10 years.

The problem associated with battery smoke detectors is that the unit can start making chirping sounds if the battery is running out of power, which can be very annoying in the middle of the night. A smoke detector that has a low battery flashing LED light will help to eliminate this problem.

Smoke Alarms For Those With Hearing Loss

The alarms we recommend all sound at 85 decibels, which should be loud enough for most people, but if you have hearing loss or are just a heavy sleeper, there are other options to consider. Some smoke alarms, such as the Gentex 7139LS Photoelectric Smoke Alarm with Plug-In Line Cord, ADA Strobe and Battery Backup, include a strobe alert, which may help. More comprehensive systems, like the Lifetone HLAC151 Bedside Fire Alarm and Clock and the SafeAwake, are also available when these bedside units pick up the alarm sound from a standard smoke alarm, they flash lights, emit a loud low-frequency alert, and vibrate a pillow shaker. The NFPA has more advice on how to start locating the best smoke alarm for your specific situation.

Where Should I Install My Smoke Detector

The NFPA recommends installing alarms inside and outside of every bedroom and on every level of your home, including the basement. Andler adds that, since smoke rises and begins gathering at the ceiling first, smoke alarms should be placed on your ceiling, not on the wall. Andler also stressed the importance of having additional smoke detectors. In the event of a fire in your home, hallway smoke detectors can sound their alarms much earlier than a bedroom alarm. Andler also says that having a smoke alarm near but not inside the kitchen reduces the chances of false alarms. The Arizona Burn Foundation recommends keeping your detector at least 10 feet away from the stove.

Our Pick: First Alert Sa511cn2

For your primary line of defense, we recommend the First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location. This is a photoelectric alarm, so its effective against both slow-burning, smoldering fires and fast-burning, flaming fires. Its sold in a two-pack, and the two units link together through a wireless signaland can combine with additional unitsso that they all sound at once. In addition, you can preset each unit to a location so that when an alarm goes off, all of the units indicate which room the fire is in. The alarm is a voice alarm, which research indicates is more effective in waking small children than a simple tone. The First Alert SA511CN2-3ST is the only alarm we found that combines the voice alarm, the location feature, and the wireless connection all in one unitat a price thats merely on the high side of average for the category.

Because theyre interconnected, the SA511CN2-3ST alarms not only give you an early warning but also tell you where the problem is originating from. During initial setup, you assign each alarm a room location. When the alarms go off, they all announce the source alarms location. As training coordinator and fire safety educator Tom Kiurski told us, Vocal smoke alarms are recommended if you have children between 4 and 12 years of age, because studies show they respond better to a familiar voice, as opposed to something that can fall under white noise.2

First Alert Battery Operated Smoke and Carbon Monoxide Alarm

Carbon monoxide is a deadly, odorless, colorless gas that can spread through a home as the result of a malfunctioning or improperly installed chimney or combustion appliance such as a gas stove, a gas boiler, a water heater, a propane range, or a wood stove, according to the Environmental Protection Agency and other sources. If you dont already have CO alarms, we strongly recommend including a few First Alert SCO501CN-3ST Combination Smoke and Carbon Monoxide Alarm with Voice Location units in your interconnected system.

This model offers the same features as our main pick and adds a carbon monoxide sensor. That CO detector adds a good bit to the pricecurrently a single SCO501CN-3ST unit is just barely cheaper than the two-pack of our top pickso we made this model a separate recommendation in case youre already covered with a stand-alone CO detector.

Most smoke and carbon monoxide detectors look the same, so you might think that they basically are the same. As long as theyve been certified by a testing organization, such as UL or Intertek Electrical Testing Labs , they should work just fine, right? Not exactly.

We need to test detectors because some fail at CO detection, and there are differences in how quickly different models respond to CO, says Bernie Deitrick, Consumer Reports test engineer for smoke and CO detectors. I have never tested a model that failed our fire and smoke tests, and it is reassuring to know that such critical devices actually work.

A detectors ability to sense carbon monoxide can mean the difference between life and death. According to the CDC, every year more than 400 Americans die from accidental CO poisoning, and about 50,000 Americans end up in the emergency department.

To determine the type you need, remove the detectors in your home from their mounts. If there are wires connected to them that run into the wall or ceiling, you need hardwired detectors. If there are no wires, you need battery-powered detectors.

Best Ionization Smoke Detector

An ionization sensor, wire-free interconnectivity, AA battery power, and a hush button make the Kidde RF-SM-DC an easy and trusty addition to your fire detection network.

  • Dimensions: 5.75″ x 5.75″ x 1.25″

  • Weight: 1 pound

  • Battery type: 3 AA batteries

  • Battery life: 6 months

Pros: Detects flash/flaming fires faster than photoelectric models, smart-touch nuisance-alarm silencer

Cons: Not sufficient at detecting smoldering fires , prone to nuisance alarms, on the large side

Because it’s best to separate your various detectors in order to monitor a wider area and range of fires, an ionization detector like the Kidde RF-SM-DC pairs well with our top recommendation, a photoelectric detector.

Ionization detectors use a light radioactive charge to create an electrical current, which, when broken, sounds the alarm. Models like this are best suited to detect the invisible particles of flash and flaming fires, while photoelectric fires are quicker to react to particles emitted by smoldering fires. By placing ionization detectors further from kitchens and bathrooms and photoelectric detectors nearer to kitchens and bathrooms, you’ll create a much more effective network.

The ability to connect up to 24 Kidde devices using neither WiFi nor hard-wired electricity makes this battery-powered device dependable, especially if you have issues with your electricity or internet service provider.
