Dual Sensor Home Smoke Alarms: First Alert 10-Year Battery

According to the National Fire Protection Association (NFPA), every 3 of 5 home fire deaths resulted from fires in houses with no smoke detectors or no working smoke detectors. When it comes to home safety, fire alarms are essential. There are many different types of smoke alarms, so choosing the best option for your home can be difficult. For example, the First Alert 10-Year Battery Dual Sensor Alarm is fully equipped with a range of features that can make it the best choice for your home. Below are the highlighted features:

Dual Sensor

There are three basic types of home smoke alarms: photoelectric, ionization, and dual sensor. Photoelectric alarms are generally more responsive to smoke from a slow, smoldering fire. Whereas ionization alarms are best at detecting smoke from a fast, flaming fire. Dual sensor alarms combine both technologies into one. The sensors work together to equip your home with comprehensive smoke and fire detection. By using both photoelectric and ionization technology, the First Alert 10-Year Battery Dual Sensor Alarm can provide the earliest possible warning, regardless of the type of fire.

Smart Sensor

When a home smoke alarm frequently sounds for false alarms, people have the tendency to take out the batteries or disconnect the alarms, which can put themselves and their family in danger. To reduce false alarms often triggered by cooking smoke or steam, First Alert offers smart sensing technology in the dual sensor alarms.  Intelligent sensing technology is designed to distinguish between real fires and nuisances, reducing false alarms significantly so there is never a need to disable the alarm.


Due to its wireless capabilities from being battery operated, it’s easy to install anywhere in your home. No wires, no electrician. Follow recommendations for placement and install the alarm either on your ceiling, or if on the wall, ensure it is within 12 inches from the ceiling.

Simple Design

For effortless use, there’s only one button for testing and silencing the alarm. Additionally, the loud 85-decibel alarm is engineered to be heard easily throughout the house.


With a built-in, sealed 10-year lithium-ion battery, the alarm will be powered over its full lifespan without needing battery changes. The lifespan of any smoke alarm is 10 years, so you’ll never have to change the battery over the lifetime of your home smoke alarm. It also has as an end-of-life warning that will sound when it’s time to replace the alarm.

The First Alert 10-Year Battery Dual Sensor Alarm meets UL217 standards and adheres to legislative requirements for 10-year battery operated home smoke alarms. It is also backed by a 10-year limited warranty.
