Overview
First Alert combines a photoelectric smoke sensor and an electrochemical carbon monoxide sensor in each of these hardwired alarms. They wire into the home's electrical system, run on a backup battery through an outage, and mount on a bracket system meant for easy alignment.
Two sensors in one housing cut the number of ceiling units, and the lower frequency horn is designed for people with age-related hearing loss. On the downside, the listing gives conflicting backup battery types and says nothing about linking several units together.
Who it's for
Homes with existing alarm wiring, and contractors who want quick swaps on job sites, get smoke and CO coverage from one device per location. Renters or households without wiring in place need a battery-only alarm instead.
Pros and cons
- Smoke and CO sensing in one housing
- Spread spectrum horn suits age-related hearing loss
- Latching alarm shows which unit triggered
- Low battery latch gives a visual warning
- Backup battery type conflicts in listing
- Needs an existing hardwired supply
- Interconnect wiring details not listed
Performance notes
Photoelectric sensing reacts to smoldering fires, and the description pairs it with an optical path design meant to cut nuisance alarms. The electrochemical cell reacts to carbon monoxide from faulty fuel-burning appliances or blocked chimneys. Mains power runs the unit day to day, with the backup battery covering outages.

Frequently asked questions
How do I test or silence a First Alert SC7010B alarm?
Each unit has a test/silence button. It checks alarm function and mutes a false alarm.
Which backup battery does the First Alert SC7010B use?
The listing conflicts. The bullets name a 2-AA battery backup, while the included contents list a 9-volt battery for each of the 3 alarms. Check the unit's label before buying spares.
How do I know which First Alert SC7010B started the alarm?
The latching alarm feature remembers which unit initiated the alarm, and the low battery latch shows visually when a unit's battery is low.
Can the First Alert SC7010B run on batteries alone?
It is built as a 120-volt hardwired alarm. The battery is a backup that keeps it working during a power outage, not the main supply.
Is the First Alert SC7010B loud enough for older adults?
It has an 85-decibel alarm with a spread spectrum horn, a lower frequency tone designed to be easier to hear for elderly people with normal age-related hearing loss.
