From The Manufacturer
The First Alert SA320CN Dual-Sensor Smoke and Fire Alarm is an advanced smoke detector that uses ionization and photoelectric sensors to provide early warning of both smoldering and flaming fires. Intelligent sensing technology helps to reduce false alarms from household triggers such as cooking smoke or shower steam. The battery-powered fire alarm installs quickly and easily with no wiring required. A loud 85-decibel siren is designed to alert even the soundest of sleepers, and a single button silences and tests the unit. Plus, it ships in frustration-free packaging so you can install it immediately.
Expert Reviews
What reviewers liked
Customer reviewers say installation of these alarms is very easy.
The First Alert SA320CN is equipped with dual-sensor capabilities, which means it includes a photoelectric sensor and an ionization sensor.
The First-Alert-SA320CN-Double-Battery-Powered smoke detector has a loud alarm so it can be heard throughout the house and responded to quickly.
It's easy to install, but can't be connected to other smoke alarms.
What makes this smoke detector unique is that it comes with a dual sensor, which means it has both an ionization sensor, which detects the presence of a flaming, fast burning fire; as well as a photoelectric sensor, which detects the presence of smoldering fires that can take a long time to ignite.
Powered by 2 AA batteries it is the cheapest alarm that has dual ionization and photoelectric sensors which work great at detecting smoke or fire.
What reviewers didn't like
AA type batteries may need replacing more often than 9-volts.
The battery-operated First Alert SA320CN falls into the latter category because it cannot wirelessly interconnect with other First Alert devices.
The design of this First Alert smoke detector is excellent, but unfortunately it cannot be interconnected to other First Alert devices.
One negative is that the dual sensors tend to create more false alarms which can be annoying, but it is better to be safe than sorry.
