A smoke detector is your first line of defense in a fire emergency. But not all smoke alarms are created equal—and not all of them are installed or maintained correctly. If your home or business is relying on outdated, battery-only detectors, you're not getting the protection you need.

At Atlanta Master Electricians, we provide professional smoke detector installation, testing, and replacement services across Atlanta and surrounding counties. Our licensed electricians ensure your smoke detectors are properly placed, code-compliant, and ready to alert you in time.

Why Smoke Detectors Matter?

According to the National Fire Protection Association (NFPA), three out of five home fire deaths occur in properties without working smoke alarms. In many cases, this is due to:

• Expired detectors

• Disconnected batteries

• Poor placement

• Lack of interconnected alarms

Professional installation ensures every room in your home or building is covered by a detector that will actually function in an emergency.

Battery-Powered vs. Hardwired Smoke Detectors

There are two main types of smoke alarms:

Battery-Powered Detectors

• Easiest to install

• Run on 9V or lithium batteries

• Require regular battery changes

• Do not alert other detectors when triggered

Hardwired Smoke Detectors

• Powered by your home’s electrical system (with battery backup)

• Installed by licensed electricians

• Interconnected: if one goes off, they all sound

• Required by modern building codes in most multi-room homes

If your home was built after 1995, hardwired detectors may already be in place—but they could be expired or installed incorrectly. If your detectors are over 10 years old, it’s time to replace them.

When to Replace a Smoke Detector?

Smoke detectors don’t last forever. The NFPA and most manufacturers recommend replacement every 10 years, even if the unit still seems functional.

Signs you need a replacement:

• Your smoke alarm is more than 10 years old

• Chirping even after replacing batteries

• Yellowing or discolored casing

• Frequent false alarms

• You’re not sure when it was last tested or installed

Our team can inspect your current system, test its functionality, and recommend compliant upgrades.

Where Should Smoke Detectors Be Installed?

To meet National Electrical Code (NEC) and local Georgia building codes, smoke detectors must be placed in:

• Every bedroom

• Outside each sleeping area

• On every level of the home (including basements)

• In hallways near stairwells

• At least 10 feet from kitchen cooking appliances

For larger homes or commercial spaces, additional alarms or combination smoke & CO detectors may be required.

Smoke & Carbon Monoxide Combo Detectors

Carbon monoxide (CO) is a silent killer, and many modern smoke detectors include CO sensors as well. We recommend dual-function units in the following areas:

• Near bedrooms

• In basements with gas furnaces or water heaters

• In garages or areas with combustion appliances

We can advise you on whether you need dedicated CO alarms, and where to place them.
