There are advantages and disadvantages of owning a wired or wireless smoke detector. Either way it is a good idea to make sure you have at least one kind properly installed and maintained. That said, let us take a look at the best choice for you.
AC vs. DC
A wired smoke detector runs off the home electrical grid. Therefore if the electric is shut or malfunctions the smoke detector will not function. What are the chances that your electric will go out before a fire is detected? Highly likely. Many fires are caused by electrical shortages and sometimes even from lightning strikes. The house electric will short out and the smoke from the fire will swirl around your wired smoke detector without causing so much as a peep. If the wired smoke detector has a backup battery option and the batteries remain fresh, it should work. On the other hand, a wireless smoke detector with maintained battery replacement, will immediately set off an alert.
Placement and Installment
Wireless smoke detectors are fairly easy to install. There is no need to hire an electrician so with this choice some money can be saved. A few screws and they are up and running. Some even offer an adhesive backing. Either way it allows the homeowner to choose the optimal location for safety. It also allows multiple installments without a problem. Wired smoke detectors are a little trickier. They must be near or wired to an electrical source. This means that if the homeowner needs to install one that is unable to easily patch into existing wires then wires will have to be run either behind or along the wall. It can be a big job and with potential aesthetic problems.
Techno From The Pros
Alarm companies will usually offer a smoke/heat detector installation package. They will professionally wire each device as well as correctly place them. Although this package is pricey it is a top of the line choice. If needed, these wired devices can instantly alert the fire department. In addition, when one wired detector goes off all of them go off. They also have a main battery backup system that alerts you when it needs changing and will allow inter-connectivity to remain engaged. The down side is that these detectors are very sensitive and can sometimes be a headache as they may beep and chirp until you call it in. Wireless smoke detectors are easy to reboot and will alert you to a low battery as well with a simple beep.
Poor Maintenance = Human Error
Each year lives are lost due to poor maintenance of smoke detectors. Namely battery replacement. Dead batteries mean dead people. They should be changed twice a year regardless of their strength upon testing. It is best to change smoke detector batteries when daylight savings time is adjusted. As mentioned above, some wired smoke detectors come with a fail safe backup battery option. Regardless, the batteries always need to be changed. Also, if a home is fortunate enough to have a backup generator then the wired smoke detector should always work, as long as there is gas in the generator tank.
