4800 specifications

The First Alert 4800 is a highly regarded smoke and carbon monoxide detector known for its reliability and advanced features. It is designed to enhance the safety of homes and businesses by promptly detecting smoke and hazardous carbon monoxide gases, which can pose serious threats to life and property.

One of the key features of the First Alert 4800 is its dual-sensor technology. This innovative design combines both photoelectric and ionization sensors, allowing the device to effectively sense slow, smoldering fires as well as fast-flaming fires. This dual approach significantly improves the chances of early detection, giving occupants crucial time to react in case of a fire emergency.

Another standout characteristic of the First Alert 4800 is its ability to detect dangerous levels of carbon monoxide. Carbon monoxide is often dubbed the "silent killer" because it is odorless and colorless, making it difficult to detect without proper equipment. The First Alert 4800 continuously monitors the air for this toxic gas, providing a reliable alarm when CO levels rise beyond safe thresholds.

The design of the First Alert 4800 incorporates a sleek and modern aesthetic that fits seamlessly into various home decors. Its unobtrusive appearance does not compromise its functionality. Furthermore, the unit features a clear digital display that indicates the levels of smoke and carbon monoxide detected, providing users with immediate information about their environment.

Installation and maintenance of the First Alert 4800 are user-friendly. The device comes with an easily accessible battery compartment and features a low-battery alert system. This ensures minimal disruption, as users can quickly replace batteries when needed. The unit is also equipped with a test button that allows users to check the functionality of the alarm with a simple press.

Another noteworthy technology included in the First Alert 4800 is its voice alarm feature. In addition to the standard alarm sounds, the device provides a voice alert that specifies the type of danger detected, whether it's smoke or carbon monoxide. This feature helps users make informed decisions in emergencies, particularly in stressful situations.

In summary, the First Alert 4800 is a cutting-edge smoke and carbon monoxide detector that prioritizes safety through its dual-sensor technology, modern design, and user-friendly features. With its reliable performance and intelligent alerts, it offers peace of mind to homeowners and businesses alike, ensuring that occupants are protected from the dangers of fire and toxic gases.
