Photoelectric Sensor Warns of Smoldering Fires

The First Alert PC910 Smoke 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 and smoke/vapor produced during showering, cooking, and other everyday activities, helping minimize the number of false alarms. A patented smoke entry system helps ensures reliable detection by providing a direct air pathway to the sensor.

Electrochemical Sensor Monitors CO Levels

The alarm also features an advanced electrochemical 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. Carbon monoxide can't be seen, smelled, or tasted in the air, and it is the leading cause of accidental poisoning deaths in America. By placing carbon monoxide detectors on every floor of the home and in each sleeping room, you can help protect your family from the danger of carbon monoxide.

Talking Voice Alarm Tells You Where the Danger Is

The First Alert Smoke and Carbon Monoxide Alarm not only alerts you when smoke or carbon monoxide has been detected, but it also tells you where the danger is. Indicator lights on the face of the unit also display the presence of smoke or carbon monoxide. The 85-decibel siren provides a clear, loud warning upon detection.

Interconnectivity for Larger Areas

The hardwired CO smoke alarm can be connected to other compatible BRK and First Alert hardwired alarms for larger buildings such as dormitories, office buildings, and apartments. Connect up to 18 compatible devices: up to 12 smoke alarms and six compatible devices like horns and repeaters. First Alert helps you create a comprehensive warning system for you and your property.

Battery Backup for Continuous Coverage

In the event of a power outage, the CO smoke alarm is still able to function thanks to its two AA backup batteries. An indicator sound is emitted when the batteries need to be replaced, and an optional drawer and mounting bracket lock help prevent tampering.
