The mounting system makes aligning and installing the combination alarm easy, while the tamper-resistant locking pins keep the alarm secure. This loud tone has a lower frequency that can be heard more easily by people with normal age-related hearing loss. If the alarm detects smoke or elevated carbon monoxide levels, it alerts you to danger with a spread spectrum horn tone.
Spread Spectrum Horn Tone Warns of Danger 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.
Carbon monoxide can’t be seen, smelled, or tasted in the air, and it is the leading cause of accidental poisoning deaths in America. When CO is detected, the carbon monoxide detector sounds an alarm to warn you of the threat. The hardwired alarm is also microprocessor-controlled to help minimize false alarms. The First Alert SC7010B Combination Smoke and Carbon Monoxide Alarm uses an advanced electrochemical CO sensor to detect elevated carbon monoxide levels from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. Electrochemical Sensor Reliably Detects CO This makes the hardwired alarm an ideal choice for installation in kitchens, near fireplaces, outside bathrooms, and in other areas that are prone to producing steam and smoke. It also distinguishes between real threats, and smoke and vapor produced during showering, cooking, and other everyday activities, helping minimize the number of false alarms. The sensor in the detector is optimized to detect larger smoke particles produced by smoldering fires, such as those caused by unextinguished cigarettes. The First Alert SC7010B combination alarm with battery backup comes equipped with a photoelectric sensor to provide the earliest possible warning of fire.
