Common Questions About First Alert Ionization Smoke Alarms

Where should I be installing ionization smoke alarms?

You should be placing smoke alarms at least 20 ft. from appliances such as furnaces and ovens as these produce combustion particles. Smoke detectors should also be at least 10 ft. from high humidity areas such as bathrooms (with showers) and laundry rooms. Heating and AC vents are also capable of disrupting smoke alarms, so you’ll generally want to place them at least 3 ft. away from them. As for actual locations, it’s generally recommended that smoke alarms be installed inside each bedroom (or area where people usually sleep), just outside of bedrooms and on every level of a home. This would include basements. You’ll find that a battery operated smoke alarm allows for a little more freedom with your selection as you won’t be limited by a hardwired setup.

Why should I replace my smoke alarms every 10 years?

Every smoke alarm in your home has an expiration date. It’s something that all homeowners should be aware of as smoke and fire protection is only available with an active alarm. If you’re unsure of the time remaining on your smoke alarm, there’s an easy way to check its viability. Most smoke detectors will feature a manufacturer date printed on the back of the alarm. If it’s more then 10 years old, it’s time to replace the smoke detector. The same applies to carbon monoxide alarms. It should be noted that most co alarms expire after 7 years.

Why does my smoke alarm randomly chirp?

There can be a few factors at play here. A low battery can be responsible as the smoke detector is alerting you that it’s time for a replacement. It can also be caused by batteries being placed incorrectly in the alarm. Another common reason is when the battery drawer is left slightly open. Similarly, a battery pull-tab that’s still in place can be causing the disruption. The chirping can also be caused by pressing the silence button by mistake. This will cause your smoke alarm to chirp once a minute for up to 15 minutes before resetting.

Why should I choose an ionization smoke alarm?

First Alert Ionization Smoke Detectors feature an ionization sensor that provides the earliest possible warning to fast flaming fires. Ionization sensors are optimized to detect fast flaming fires that can be caused by paper, kitchen grease and other fast-combusting materials. 

How about First Alert Ionization Smoke Alarms?

All First Alert Hardwired Ionization Smoke Alarms come equipped with a battery backup that ensures continued operation in the event of a power outage. First Alert Combination Alarms that implement ionization sensors offer dual protection from smoke and carbon monoxide. This will allow you to create a smoke, fire and carbon monoxide defense system by interconnecting First Alert Hardwired Smoke Alarms with one another. Battery operated ionization smoke detectors are also available and provide plenty of versatility when it comes to the installation process.
