What are the differences between Smoke, carbon monoxide, and heat alarms, and where are they needed?
There are two different types of smoke alarms for sensing “fires”. Ionization and/or photoelectric. Ionization tends to respond quicker to smoke that is produced by flaming fires, whereas photoelectric is seen to respond quicker to smoke produced from smoldering fires. Due to this, most fire departments recommend alarms that are combined, meaning they have both these sensing qualities. Carbon monoxide alarms, or CO alarms, are best suited to be placed at waist or ceiling level, either mounted or in outlets (plugin). This is because CO rises as it is lighter than air, and is carried by warm, rising air (EPA). They sell alarms that are ionization, photoelectric, and CO that are perfect for homes.
According to the U.S. Fire Administration (USFA), there are approximately 6,600 garage fires every year that result in an average of 30 deaths, 400 injuries, and $457 million in property loss. Most people do not think about the dangers that are lurking in their garage. We recommend installing Heat Detectors in your garage. HEAT detectors are placed inside your garage for when the temperature of your garage becomes too high. Heat detectors are more reliable than smoke detectors when placed in areas that could be dusty or dirty. Excessive heat could activate the alarms, but for those of you that keep animals in your garage, this could be beneficial.
As far as placement goes, one in each bedroom, multiple in the basement depending on size, in hallways throughout the home, and common areas. Keep them out of the direct kitchen area or they will be going off very often.
