Smoke detectors are used to detect the presence of smoke in a room or building. There are many different types of smoke detectors, but all work by detecting either the presence of smoke particles or the change in temperature caused by a fire.
Smoke detectors can be either battery-powered or hard-wired. Battery-powered detectors usually contain a small battery that powers the detector. When the battery runs low, a warning light will typically turn on to indicate that it is time to replace the battery. Hard-wired detectors are connected to the building’s electrical system and usually have a longer lifespan than battery-powered detectors.
Smoke detectors should be installed in every room of a house, as well as in hallways and other areas where a fire could potentially start. They should also be tested regularly to ensure that they are working properly.
Smoke detectors can save lives. In the event of a fire, a smoke detector will sound an alarm, warning occupants of the building of the danger. This gives people enough time to evacuate the building before the fire becomes too large. Smoke detectors are also important for firefighters. When a fire is burning, smoke can spread quickly and cause firefighters to become disoriented. A smoke detector can help firefighters locate the source of the fire and help them put it out more quickly.
Smoke detectors are an important part of any home or building safety plan. They can save lives by giving people enough time to evacuate before a fire becomes too large.

What to look for when buying a smoke detector:
-Type of alarm
=The most common type of smoke detector is electrically powered, which means that it requires electricity to operate. This is either 110 or 120 volt AC house current or a 9 volt battery. The low voltage electrically powered detectors are usually battery-operated and have an LED lighted power status indicator. They can be plugged into an AC outlet but will not receive power if the AC is turned off or there is a power outage. Others are hard wired into the home’s electrical system, and some battery-powered units have both options of powering them with low voltage batteries, house current or 110 volt AC plug in adaptors.
=Smoke detectors that are “plug in” will only work when the electrical breaker has not been turned off. With no house current, it does not matter if you have set up your smoke detector on an AC outlet.
=This is typically either ceiling or wall mountable (vertical or horizontal). Vertical is the more common in the US and Canada, while horizontal is preferred in Europe.
=Most smoke detectors come with a mounting bracket that allows for standard 8′ to 10′ ceiling heights. If you have an unusually high or low ceiling then check that your smoke detector can be mounted at this height.
