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.

This is our second First Alert Hardwired Photoelectric Smoke and Carbon Monoxide Alarm with battery backup-SC7010B. The first one needed replacing after 7 years! We like the product and found it easy to install. The personal service from folks at First Alert in clarifying was outstanding!

Hardwired Photoelectric Smoke and Carbon Monoxide Alarm - SC7010B

I have been using First Alert products for many years with no problems. This was a replacement unit for an end of life unit. Upgraded to a 2 in 1 unit for better coverage.

Good to have a CO detector.

House was built before CO detectors were required so put one in when the old smoke detectors reached 10 years old. Easy to install and works fine.

Too keep up with building codes. Combination units are required in Colorado. If these units go off my smoke alarms will also go off. Much better then the plug in CO detectors that are not inter-connected

The product was excellent and came promptly.

Why Is My Smoke Alarm Beeping?

Smoke alarms can beep for to the following reasons:

  • Low Battery: This is the most common cause. Most smoke detectors use a chirping sound (usually a single beep every 30-60 seconds) to warn you that the batteries are running low and need to be replaced. Don't wait until the alarm is silent - replace the batteries right away to ensure your smoke alarm continues to function properly.
  • End of Life: Smoke alarms don't last forever. If your smoke detector is beeping constantly or in a different pattern than the low battery chirp, it may be nearing the end of its intended lifespan and should be replaced altogether.

Hardwired Photoelectric Smoke and Carbon Monoxide Alarm with Battery Backup

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.
