This smoke detector with ionization sensor has a tamperproof design, a mute feature, a power LED and alarm indicator, and end of life signal, and single test button.
Ionization Sensor Reliably Detects Flaming Fires
The First Alert 10-Year Sealed Battery Ionization Smoke Alarm comes equipped with an ultra-reliable ionization sensor to provide the earliest possible warning of a fast-flaming fire. The sensor is optimized to detect flaming fires, such as those caused by paper, kitchen grease, and other fast-combusting materials.
No Battery Changes for the Life of the Alarm
The First Alert 0827B Sealed Ionization Smoke Alarm features a built-in 3-volt lithium power cell that lasts for 10 years, so you never have to worry about battery changes for the life of the alarm. Using a smoke detector system with a sealed battery provides the ultimate in longevity and security, preventing possible lapses in protection.
Tamperproof Design Prevents Battery from Being Removed
Thanks to a tamperproof design, the batteries in the First Alert 0827B Sealed Ionization Smoke Alarm can’t be removed. This smoke detector complies with current 10-year legislation in states/cities where required, making it a great addition for any number of properties where sealed/tamperproof alarms are required.
If the alarm goes off accidentally, simply press the silence button to stop the noise. The same button allows you to test the alarm to ensure it is working properly. An LED indicator blinks to let you know the smoke detector is receiving power and working regularly. When the alarm reaches the end of its service life, it will chirp once a minute to let you know the battery is almost depleted. This smoke alarm features a Perfect Mount system for easy alignment and installation.

First Alert 10 year Battery Operated Smoke Alarm
We have used this product before and needed to replace the ones installed 10 years ago. We like this product because we never had to worry if we had failed to replace the battery periodically. Best purchase ever.

This is our third set of 10-year smoke detectors. They are the best, and we have had no problems. My husband retired from the Fire Service after 43 years, hence we have the best fire protection money can buy. We have one in each room in the house, and we have COs upstairs and in the basement.
