SA320CN specifications
The First Alert SA320CN is a highly regarded smoke and carbon monoxide detector designed to provide comprehensive safety for households and residential spaces. Renowned for its reliability, this unit employs advanced technologies to ensure the early detection of smoke and toxic gases, offering peace of mind to homeowners.One of the standout features of the SA320CN is its dual-sensor technology, which combines both photoelectric and ionization sensors. This dual approach enhances the unit’s capability to detect a wide range of fire types. Photoelectric sensors are particularly effective at sensing slow-smoldering fires, while ionization sensors excel in detecting fast-flaming fires. This results in quicker, more accurate alerts, giving families critical time to react in an emergency.
The SA320CN is also equipped with an electrochemical carbon monoxide sensor. This specialized sensor accurately measures CO levels in the home and triggers an alarm when dangerous concentrations are detected. Given that carbon monoxide is an odorless and colorless gas, having a reliable detector is crucial for safety.
Installation and usability are key considerations for any home safety device. The First Alert SA320CN features an easy, hassle-free installation process. It comes with mounting hardware, and its compact design ensures it fits easily in various locations throughout the home. Additionally, the detector includes a convenient voice alert feature, which announces the type of danger detected—whether it is smoke or carbon monoxide—allowing users to react more effectively.
Another important characteristic is the unit's battery life. The SA320CN is powered by a sealed lithium battery, which can last up to 10 years. This long battery life reduces the inconvenience of frequent battery replacements and ensures that the unit remains operational for an extended period. Furthermore, the detector features a low battery chirp, alerting users when it’s time to replace the entire unit.
The First Alert SA320CN also encompasses safety features such as a silence button, which allows occupants to easily hush unwanted alarms caused by cooking smoke or steam. With its combination of dual sensors, a reliable carbon monoxide alarm, and user-friendly design, the First Alert SA320CN stands out as a dependable choice for safeguarding homes against the dangers of fire and carbon monoxide exposure, ensuring that families can sleep soundly.
