First Alert Hardwired Combination Photoelectric Smoke and Carbon Monoxide Alarm with Battery Backup - SC7010BA

The First Alert SC7010BA Hardwired Combination Smoke and Carbon Monoxide Alarm with Battery Backup 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. If a threat is detected, the alarm emits a spread spectrum horn tone that is designed to be heard by people with age-related hearing loss.

  • Photoelectric Sensor Warns of Smoldering Fires

The First Alert SC7010BA 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 and vapor produced during showering, cooking, and other everyday activities, helping minimize the number of false alarms. This makes the alarm an excellent choice for installation in kitchens, near fireplaces, outside bathrooms, and in other areas that are prone to producing steam and smoke.

  • Optipath 360 for Comprehensive Detection

Optipath 360 technology enhances the alarm’s detection abilities by providing the sensor with 360-degree access to the layer of air around the ceiling. This allows the sensor to detect smoke, combustion particles, volatile components, and other fire signatures in the surrounding air more easily.

  • Electrochemical Sensor Reliably Detects CO

The First Alert SC7010BA 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. The alarm is also microprocessor-controlled to help minimize false alarms. When CO is detected, the carbon monoxide detector sounds an alarm to warn you of the threat. 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.

  • Spread Spectrum Horn Tone Warns of Danger

If the alarm detects smoke or elevated carbon monoxide levels, it alerts you to danger with a spread spectrum horn tone. This loud tone has a lower frequency that can be heard more easily by people with normal age-related hearing loss.

  • Easy to Install and Operate

The mounting system makes aligning and installing the alarm easy, while the tamper-resistant locking pins keep the alarm secure. 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 timer, you can know exactly when it is time to replace the alarm. AC-powered smoke alarms must be installed in accordance with all local electrical codes.

  • Battery Backup for Detection During a Power Outage

This smoke alarm is designed for hardwired installation, but it also features a battery backup that helps ensure continued functionality in the event of a power outage. The unit comes with two AA batteries.


  • 120-volt hardwired smoke and carbon monoxide alarm wires directly into your home’s electrical system
