Different Kinds of Smoke Detectors

There are two main kinds of smoke detectors – ionization and photoelectric. Both types of smoke detectors effectively sense smoke, and both are required to pass the UL certification. However, there are key differences in the way they operate and in how they respond to smoke. Ionization This type of detector has a continuous current running between two electrodes, and when smoke goes into the unit, the current is interrupted, and the alarm sounds. The drawback to this type of smoke detector is that it cannot tell the difference between steam and smoke. This makes ionization smoke detectors subject to false alarms when placed near kitchens and bathrooms. They tend to respond to things like burnt toast and hot showers. The advantage of ionization detectors over photoelectric detectors is that they are less expensive and react more quickly to flaming fires. In addition, when the battery starts to fail, these detectors will alert you to change the battery because the alarm will sound. Photoelectric This type of detector responds to a reduction in light reaching an internal photocell. When smoke goes into the unit, the light is scattered, and the alarm sounds. These detectors respond more quickly to smoldering fires than ionization smoke detectors. In addition, because these detectors are less likely to send out a false alarm, they are less likely to be a nuisance. However, this type of smoke detector will not alert you when the batteries are dead. Whichever smoke detector you decide to use, both should have their batteries changed annually. Mr. Electric recommends picking a day every year that you will remember, like New Year's Day or your birthday, and going around the house to test your detectors and change the batteries.

Smoke Detector and Fire Safety Tips

Here is a list of tips to follow to help keep you and your family safe. Have at least one smoke detector on each level of your house. Check the operation of your smoke detectors and alarms every six to twelve months. Be sure to have a battery-powered backup in your smoke detectors (rechargeable batteries are not recommended). Avoid placing smoke detectors near drafts, doors, and windows. Be sure that your smoke detectors are centered on the ceiling and that they are at least six inches away from the wall. If you have a wall unit, make sure that it is at least one foot below the ceiling. The best location for smoke detectors is near bedrooms, in hallways, and at the top of stairwells. To keep dust from building up within the smoke detector, lightly vacuum the detector annually. Do not pull the unit from the wall to try to turn off a false alarm. Do not remove the batteries except to change them. Thirty percent of smoke detectors don't work because the user has removed the battery and forgotten to replace it. If you cannot afford smoke detectors, please get in touch with your local fire department. They will let you know about local programs to help the elderly and people experiencing poverty. Keep at least one fire blanket somewhere in your home. Keep at least one fire extinguisher somewhere in your home. Establish an emergency exit plan with your family. Once you leave home, DO NOT return! Many people have lost their lives going back to their homes. Wait for firefighters to arrive.

How do I test my smoke detector?

First, push the test button on the smoke detector to see if the alarm sounds. This will let you know if the battery is working or if the electrical power is connected. Second, test the smoke detector by placing a lit match or a lit candle 6 inches below it to see if the alarm will sound. If the alarm does not sound, blow out the candle or match and see if the smoke sets it off. If the smoke detector still does not go off, then you may need to replace the unit. It is important to remember that just because the power is working, it does not mean the smoke detection device is working. Be sure to check them both. Putting you or your family at risk of carbon monoxide poisoning or a dangerous house fire is senseless.

Carbon Monoxide Detectors

People who are unconscious due to inebriation or sleep can die before they ever experience the symptoms of carbon monoxide poisoning. In addition, depending on the levels of carbon monoxide in the air, you can die within minutes or hours. A carbon monoxide detector will alert you and your family when there is a risk of being poisoned.
Carbon monoxide is found in many household appliances like gas ranges or stoves, gas clothes dryers, water heaters, furnaces, and gas or wood fireplaces. Fuel-burning space heaters, exhaust from cars, gas or charcoal grills, and clogged chimneys or flues can also produce carbon monoxide. If items like these are in poorly ventilated areas, carbon monoxide can build up. Before you know it, you're surrounded by toxic air that will poison you if you inhale.

Look for warning signs like:

Dizziness
Headaches
Nausea
Light Headedness
Sleepiness
Fatigue or Weakness
Irregular Breathing
Vomiting
Shortness of Breath
Confusion
Chest Pain
Food Poisoning

Monitor dangerous levels of carbon monoxide in your home with a carbon monoxide detector.

How can I prevent carbon monoxide poisoning?

Have CO detectors installed in your home. At a minimum, have one installed on every level of your home and outside each bedroom. 
Change the batteries in your CO detector every six to twelve months. 
Look for Underwriters' Laboratories or the American Gas Association seal of approval when purchasing gas equipment. 
Have your gas appliances checked annually. 
Do not use flameless chemical heaters indoors or in enclosed spaces. They burn gas and will allow CO to build up to toxic levels. 
Have a service expert repair any gas appliance that is not functioning properly. 
Be sure to open the flue when enjoying a fire in the fireplace or furnace. 
Do not use a gas oven to heat your home. 
Do not run a generator, vehicle, or other fueled motors inside. Even if the garage door is open to the exterior, CO can still build up to toxic levels. 
Only use grills outside in a well-ventilated area. 
Use battery-powered heaters when camping. 
Keep all gas appliances properly adjusted and use an exhaust fan where appropriate. 
Know the difference between the sound of your smoke alarm and your CO alarm. 
If you cannot afford a CO detector, contact your local fire department. There are programs to help the elderly and people experiencing poverty.

Smoke Detectors

The U.S. Fire Association (USFA) reported 397,650 fires between 1998 and 2007. Annually, these fires caused 3,040 civilian deaths and 14,960 civilian injuries.

In the United States, most state and local laws require that smoke detectors be present in any place where there is human habitation. These laws require that smoke detectors be near every bedroom in the house, and in some cases, they must be present in stairways, halls, and garages. In addition, new construction laws require that smoke detectors be hooked up to the electrical wiring, be interconnected, and have a battery backup system in place.

The National Fire Protection Agency highly recommends replacing your smoke detectors every ten years because, as the system ages, the electrical components become less reliable.
