The First Alert SCO7CN Battery-Operated Combination Smoke and Carbon Monoxide Alarm with Voice and Location delivers both smoke and carbon monoxide detection in a single unit. Equipped with a photoelectric smoke sensor and an electrochemical CO sensor, it accurately detects smoke produced by smoldering fires and carbon monoxide leaks from multiple sources.
Talking Alarm Indicates Location and Nature of Threat: The First Alert SCO7CN Combination Smoke and Carbon Monoxide Alarm features a talking alarm that not only provides a verbal warning of the danger, but also tells you its location, so you can plan the safest possible escape. Easy to program and operate, the talking alarm allows you to choose between 11 pre-programmed home locations. Indicator lights on the face of the unit display the presence of smoke or carbon monoxide, while an 85-decibel alarm provides a clear, loud warning upon detection.
Photoelectric Sensor Warns of Smoldering Fires: The First Alert SCO7CN alarm comes equipped with a photoelectric sensor to provide the earliest possible warning of fire. The sensor is optimized to detect larger smoke particles produced by smoldering fires, such as those caused by unextinguished cigarettes. It also distinguishes between real threats, smoke and vapor produced during showering, cooking, and other everyday activities, helping minimize the number of false alarms.
Electrochemical Sensor Monitors CO Levels: The alarm also features an advanced electrochemical CO sensor that detects carbon monoxide leaks from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. The detector stores CO readings and verbally communicates the highest level of CO detected, allowing you to discern patterns that indicate potential leaks from an appliance, a generator, or other carbon monoxide source.
Battery Powered and Easy to Operate: Powered by two AA batteries, this alarm is easy to set up and does not require any wiring. The unit features a pivoting, easy-to-access battery drawer that allows you to replace the batteries without dismounting the alarm. A one-touch silence/test button makes it easy to test the detector or mute it in the event of a false alarm. And thanks to the end-of-life warning, you can know when it is time to replace the alarm.
