How Do Wireless Smoke Detectors Work?

Like their name says, wireless smoke alarms do not require wiring or an electrician to install. When one alarm senses fire and sounds, any other alarms throughout the home or building will also go off regardless of where the fire is located. This ensures more warning in more places, which can save lives.

Many building codes require that new construction have what is referred to as "interconnected smoke detector systems" in place. Wireless smoke detectors are much cheaper to install than traditional interconnected systems that are hardwired and perform the same function.

How Do they Do It?

• Wireless smoke detectors use radio frequency, or RF, transmitters to communicate with each other. When a smoke detector senses smoke, the RF transmitter goes into action, sending signals to all the other detectors connected throughout a home or building.
• These alarms are usually hooked up with an AC adapter to an electrical outlet or use a battery. Many have an AC adapter with a battery backup.
• Each wireless smoke alarm comes with over 200 different identification systems to ensure your smoke detector will not accidentally transmit or receive information about what is taking place in another building.

Special Features

• Unlike traditional smoke alarms that sound a loud, high-pitched noise, many wireless smoke detectors shout out commands like "Danger! Fire! Wake up! Follow the Escape Plan!" in addition to emitting low-frequency tones.
• Studies have shown that children are more likely to sleep through an alarm yet wake up at the sound of a voice, and lower frequency tones can help elderly people who may suffer from age-related high-frequency hearing loss.

How to Place Smoke Detectors in an Attic

Smoke detectors are wonderful life saving devices that allow people to have advanced warning when a fire breaks out. Putting a smoke detector on every level of your home and near sleeping areas can save your life. Smoke detectors in finished attics are a necessity as well, since finished attics are part of the living space of a home. Smoke detectors cannot be used in unfinished attics because the temperature fluctuations and dust found in attics can cause the smoke detector to malfunction. Read on to learn how to best place smoke detectors in finished attics.

• ake the mounting bracket for the smoke detector out of the packaging. Typically, it is on the smoke detector itself. One half of a unscrewing rotation should disengage it.
• Hold the smoke detector bracket against the ceiling where you want to install it. Experts recommend placing it near the stairwell leading up to the attic from the floor below.
• Screw the mounting bracket to the ceiling using the screwdriver and the screws enclosed with the smoke detector. You may use drywall anchors if necessary.
• Replace the batteries in the smoke detector, if desired. Dependent on how long the device has been sitting on a shelf, the included batteries may be less than fresh.
• Install the smoke detector onto the mounting bracket by attaching it using the reverse motion that you used to remove it.
• Replace all the smoke detectors in the house with more of the wireless interconnectable kind to ensure that if one is triggered, they all sound. This is especially important in a remote area such as an attic, where someone may not hear the lone attic alarm going off.
