FIRST ALERT BRK SC7010B-3 Hardwired Smoke & CO Alarm (3-Pack) with Battery Backup

The FIRST ALERT SC7010B-3 3-pack brings together smoke and carbon monoxide protection in a single, hardwired system. Each unit combines a photoelectric smoke sensor with an electrochemical carbon monoxide sensor, leveraging Optipath 360 technology to broaden coverage while reducing false alarms. With a built-in battery backup, these alarms stay powered during outages, helping keep spaces monitored around the clock.

Designed for modern homes and small facilities, the SC7010B-3 uses a spread-spectrum horn that can be heard clearly by people with age-related hearing challenges, ensuring critical alerts reach occupants. The alarms are intended for 120-volt hardwired installation and include a low battery latch that visually signals when the battery needs replacement. A convenient test/silence button makes routine checks straightforward, while the dust cover helps protect sensors during renovations or cleaning.

What’s in the box:

• Three 120-Volt hardwired combination photoelectric smoke and electrochemical CO alarms with battery backup
• 2-AA battery backup option, silence/test button, dust cover, and an 85-decibel alarm
• Spread spectrum horn designed to be audible for occupants with hearing challenges
• Intuitive latching alarm feature that remembers which unit triggered an alert, plus a visual low-battery latch
• Perfect Mount System for precise alignment and quick installation across multiple rooms

Smart protection you can rely on

Each unit blends proactive sensing with practical design for everyday use. The photoelectric sensor excels at detecting smoke from smoldering fires, while the electrochemical CO sensor catches risky gas leaks from appliances or blocked vents. The combination of sensors in a single device helps simplify installation without sacrificing awareness in key living areas.

Installation and daily use

Thanks to the Perfect Mount System, installation is fast and alignment remains accurate across placements. The low battery latch provides a quick visual cue when service is needed, and the test/silence button allows for quick confirmation of function and nuisance-alarms management. The dust cover helps keep sensors clean during renovations or cleaning tasks.

Ideal for homes with multiple bedrooms, apartments, condos, and small offices that require reliable 24/7 monitoring. Use the 3-pack to cover common living spaces—hallways, kitchens, and entryways—with a single, cohesive alert system that’s easy to manage and maintain.
