Smoke detectors: what you need to know
Smoke detectors, also known as fire or smoke alarms, are electric fire-protection devices that identify the presence of smoke using ionization or photoelectric technology. These small, yet mighty devices alert you to house fires, potentially saving your life.
To best protect yourself, you should have a smoke detector in every room of your house or at least every 30 feet. Placement is just as important—install your smoke detectors no more than 12 inches from the ceiling and keep them away from kitchen appliances to prevent false alarms.
Lastly, press and hold the test button on your smoke detectors monthly to ensure they are operating correctly.
Key takeaway One smoke detector isn’t enough. You need one for every room or at least every 30 feet.
How much do smoke detectors cost?
The cost of a smoke detector ranges from $10 to $120, depending on specialized features.
Basic models typically run on replaceable batteries without additional features. The most expensive models have smart features, hardwiring with backup batteries, carbon monoxide detection, dual-smoke detecting functionality, and even voice alerts.
Types of smoke detectors
There are three main types of smoke detectors, named for the technology used to detect smoke:
- Ionization smoke alarms send a low-level electrical current through ionized air. Smoke disrupts this electrical current, triggering the alarm. Ionization smoke alarms respond faster to the smoke produced by flaming fires.
- Photoelectric alarms detect smoke with a light sensor and beam. Usually, the light beam points away from the sensor. However, when there’s a fire, the smoke disrupts the beam, redirecting the light to the sensor. These can detect large, visible fires sooner than ionized sensors.
- Dual sensor smoke alarms use a combination of ionization and photoelectric technology to give you the best of both worlds. Combination sensors often also incorporate carbon monoxide (CO) detection to trigger an alarm when CO gas in the air reaches unsafe levels.
Key takeaway Dual sensor smoke detectors use a combination of technology to detect fast and slow-burning fires.
What to look for in a smoke detector
Basic smoke detectors will do the job, but the latest models provide features for convenience and better protection. Here are some of the most useful features we’ve identified:
- Interconnectivity. When one alarm goes off, they all go off, so you don’t have to worry about being unable to hear a distant alarm
- Hardwiring with backup batteries. Instead of choosing between hardwired or battery-powered options, you can find smoke detectors with both features
- Security system integration. Smoke detectors with security system integration alert authorities when there’s a fire. This is great for heavy sleepers
- Hush buttons. Say goodbye to fanning the smoke detector when you’ve burnt your toast
- Smart technology. Some of the newest models offer wifi interconnectivity and an app to notify you before it triggers the siren. These models also boast voice alerts and self-testing

Smoke alarm maintenance tips
Even if your smoke alarm has self-testing functionality, it’s wise to test it once a month. If the detector doesn’t emit a loud, ear-piercing sound, you might need to replace your batteries. Batteries should be replaced at least every 8 to 10 years unless otherwise indicated.
In addition to this, you’ll want to make sure the smoke detector is clear of any dust or debris to prevent malfunctions. Consider cleaning your smoke alarm at least every six months or according to the manufacturer’s instructions.
Does home insurance cover fire or smoke damage
Standard home insurance policies include protection from sudden or accidental fire or smoke damage. Depending on the amount of your coverage, home insurance will help to pay for repairs or the complete rebuild of your home.
Home insurance policies also generally cover detached structures, personal property, and personal liability. That way, if your fence or furniture is damaged in a fire, or if a house fire on your property damages your neighbor’s home, then you’ll likely be covered.
If you’re unsure about your coverage limits, call your home insurance company to discuss your policy.

FAQs
Can smoke detectors detect carbon monoxide?
Generally, smoke detectors and carbon monoxide (CO) detectors are separate devices, but there are some hybrid models that can also detect carbon monoxide. Smoke detectors monitor the presence of smoke particles or heat, and carbon monoxide detectors monitor levels of invisible and odorless gas. Unless your smoke detector specifies the detection of both smoke and carbon monoxide, it’s important to get a separate device.
When should you replace your smoke alarm?
Most smoke alarms have a replace-by date stamped or printed on them. If yours doesn’t, then you should replace it at least every 8 to 10 years. Remember to test your smoke alarm once a month, as it can fail from constant exposure to dust, insects, or corrosion.
Does home insurance cover smoke and fire damage?
Most standard home insurance policies cover your home against smoke and fire damage, including damage from wildfires. It's always a good idea to double-check your policy for coverage limits and limitations to ensure you're sufficiently covered in the event of a disaster.
