Common Questions About First Alert Dual Sensor Smoke Alarms and Smoke Detectors

Where should I be installing dual sensing 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 a dual sensor smoke alarm?

Dual sensor smoke alarms excel at detecting the presence of both smoldering and fast-flaming fires, ensuring optimal levels in peace of mind. Both sensors work together to provide complete smoke and fire detection. The photoelectric sensor detects smoldering fires from objects like cigarettes burning on furniture or in trash cans. The ionization sensor excels in detecting fast-flaming fires like erupting kitchen grease fires or combustibles. For maximum protection and full coverage from all types of fires, your best option is to use a dual sensor smoke detector that features both photoelectric and ionization sensing technologies.
