The First Alert SC7010B 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 SC7010B 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. 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° 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 SC7010B 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 perfect mount 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.
Photoelectric Smoke and Carbon Monoxide Alarm SC7010B
In this guide, we'll be showing you how to install First Alert Hardwired Smoke and Carbon Monoxide Alarms. Here are a few items you'll need before starting the installation process: Needle-nose pliers or utility knife, screwdriver, wire stripper, wire nuts and a ladder.
Hardwired Smoke or Carbon Monoxide Alarm Requirements:
To begin, turn off power at the junction box and connect your alarm to the building's electrical wiring.
|Attach to black wire on power connector|
|Attach to white wire on power connector|
Standalone (single-station) alarm: This wire is not needed; tuck the orange wire into the junction box.
If you are installing more smoke or carbon monoxide alarms, you'll want to repeat the process throughout the building. Interconnected smoke and co alarms must meet all requirements:
The same fuse or circuit breaker must power all interconnected alarms.
Up to 18 compatible detectors can interconnect, with a limit of 12 smoke alarms.
The total length of wire interconnecting the alarms should be less than 1,000 ft. (300 meters). This type of wire is commonly available at hardware and electrical supply stores.
All wiring must conform to all local electrical codes and NFPA 70 (NEC). Refer to NFPA 72, NFPA 101, and your local building code for more information.
Interconnect wiring diagram:
If you have any doubts or reservations about these interconnect requirements, please contact an experienced electrician to install your wiring and hardwired alarms.
Once you've installed your hardwired alarms, you'll want to restore power to the junction box. Under regular operation, the power indicator light on the alarm will shine/blink to indicate that it is receiving AC power.
Here's how you can test standalone or interconnected alarms:
Standalone Alarms: Press and hold the Test/Silence button until the unit triggers an alarm.
Interconnected Alarms: Press and hold the Test/Silence button until the first unit triggers an alarm. All interconnected detectors should sound off. Repeat this process to test each alarm in the interconnected series.

wake up the dead!!!!
easy to install especially if you already have the newer bases installed-also like the AA cells replacing the older 9 volt-the horn on these CO detectors should wake up the dead-it is horrible sounding-just what you want...

First Alert smoke/CO2 Alarm
The unit was very easy to order from the First Alert store. I had originally tried to purchase replacement units from local retailers who did not carry my particular model in their inventory. The on-line ordering process was fast, easy, and efficient. I installed the unit with the instructions included with the alarm which I found particularly helpful because they explain the meanings of the beep sequences during alarm testing.
