Hardwired VS. Battery Smoke Detectors
It’s imperative that you have a smoke detector in your home. However, the big question is whether you should have one that is powered by batteries or one that is hardwired into your home. There are several variables to consider when making your choice such as reliability and how much you can afford to pay.
How Does a Smoke Detector Work?
Smoke detectors work either through ionization of air or through a photoelectric process. An ionized smoke detector comes with a small amount of radioactive material to facilitate the ionization process. If smoke enters the ionization chamber, it will disrupt that process and issue an alert.
With a photoelectric detector, an alert is issued when smoke scatters the light inside of the detection chamber. The detector will pick up on the fact that the light pattern has changed and quickly start to beep or buzz to provide everyone in your house with extra time to escape.
Potential Benefits of Hardwiring a Smoke Detector
Perhaps the best reason to hardwire a smoke detector into your home is that you can actually connect multiple detectors into a single network. In other words, you could have a detector in the living room sync up with one in your bedroom, a child’s bedroom and the guest room. When one detector goes off, the others will also beep, flash or otherwise alert everyone to the presence of a fire.
Another potential benefit of hardwiring a smoke detector into your home is the fact that it will typically last for up to 10 years. Although products powered by batteries alone can also last up to 10 years, they typically last for five or less. In addition, since items that are wired into your home don’t need batteries, you won’t have to worry about replacing them during the product’s useful lifespan.
You also won’t have to worry about a battery too weak to make any noise or deal with the chirping sounds that occur when a battery is at low power. It is important to note that some hardwired products come with a backup power source that means your system is still operational during a power outage.
Why Should You Consider a Battery Smoke Detector?
Professionals often recommend that you have a smoke detector wired directly into your home. However, this doesn’t mean that a battery smoke detector is always an inferior product. For instance, they tend to generate fewer false alarms, which means that you are less likely to ignore them.
Meanwhile, they tend to be easier to turn off when a false alarm does occur because you’re dealing with a single detector instead of an entire network. This can be ideal for scenarios such as when burnt food or steam created in a nearby bathroom shower sets off the detector.
They are also easier to install and move when you feel the need to make a change. For instance, you may decide that you don’t want a smoke detector in the guest room that no one uses. Instead, you can move it to your new baby’s room or another area that is used on a more frequent basis.
Battery smoke detectors are also much easier to install compared to a hardwired product. This is because you don’t need to integrate detector wires with those already in your home. Instead, you can simply place them on a shelf, mantle or other location where it can reliably pick up a smoke signal.
Finally, a battery smoke detector can be ideal if you’re on a budget. Generally speaking, a portable detector is less expensive than its wired counterpart, and in many cases, batteries can last for months or years without needing to be replaced. Ideally, you’ll check your smoke detector once a year to ensure that the batteries are working properly.
What to Consider When Making Your Choice
The size of your living space is perhaps the most important consideration when deciding which type of detector to choose. If you live in a smaller home or apartment, it may be best to have a single battery detector. In such a scenario, it should be sensitive and loud enough to detect and alert you to smoke or fire in a timely manner. However, if you live in a larger home or need coverage for an entire building, a hardwired product is often best.
Of course, your budget is also going to be a significant factor when determining what type of product to buy. Items that wire into your home generally require a greater upfront investment. This is partially because you’ll need a professional to install it in your home safely and properly.
Finally, you’ll need to decide whether you want to replace batteries and detectors every few years or once per decade. If you don’t mind spending more time performing routine maintenance, a battery smoke detector might make the most sense for your needs.
