SCO5B specifications
The First Alert SCO5B is a cutting-edge combination smoke and carbon monoxide (CO) detector designed to enhance safety in homes and businesses. With its sleek design and advanced technology, this device serves as a reliable guardian against two of the most dangerous threats: fire and carbon monoxide poisoning.One of the standout features of the SCO5B is its dual-sensor capability. This combination detector utilizes both photoelectric and ionization sensors. The photoelectric sensor is particularly effective at detecting smoldering fires, which burn longer and produce more smoke, while the ionization sensor quickly detects flaming fires. This dual-sensor functionality ensures a more comprehensive detection system, providing quicker alerts in case of fire emergencies.
Equipped with advanced electrochemical sensor technology, the SCO5B also offers enhanced CO detection. This technology is known for its accuracy and reliability in detecting elevated levels of carbon monoxide, a colorless and odorless gas that can be lethal in high concentrations. The device features a loud 85-decibel alarm that sounds when CO is detected, ensuring occupants are alerted quickly to potential dangers.
Another notable characteristic of the SCO5B is its convenient battery backup system. In the event of a power outage, the device continues to operate on its backup batteries, ensuring round-the-clock protection. The unit operates on three AA batteries, which are not only easy to replace but also provide long-lasting performance.
The First Alert SCO5B also incorporates a unique safety feature: a voice alert system that clearly announces “Fire!” or “Warning! Carbon Monoxide!” This spoken alarm helps distinguish the nature of the threat, allowing residents to respond appropriately and quickly.
Installation is made simple with the included mounting hardware, and the detector’s compact profile doesn’t take up much space on walls or ceilings. Additionally, the SCO5B comes with a convenient test/silence button, allowing users to easily test the unit or silence any unwanted alarms.
For those who prioritize the safety of their loved ones, the First Alert SCO5B offers the peace of mind that comes from knowing they are protected from the dual threats of fire and carbon monoxide. Its combination of advanced technologies, reliable alarm systems, and convenient features make it a top choice for anyone looking to enhance their home safety measures.
