First Alert SC5 Smart Smoke & Carbon Monoxide Alarm, 2-Pack, Precision Detection Technology, Wireless Interconnection & Mobile Alerts

Product Description

Upgrade your home's fire and carbon monoxide safety with the First Alert SC5 Smart Smoke & Carbon Monoxide Alarm, 2-Pack. Designed to provide smart alerts and connected protection, these combination alarms detect smoke and carbon monoxide (CO), helping you stay informed about potential hazards whether you're at home or away.

Smart Alerts Through the First Alert App

Connect compatible alarms to the First Alert app to receive mobile notifications when smoke or carbon monoxide is detected. The connected features help you monitor alarm status and stay informed about potential emergencies when you're away from home.

Precision Detection Technology

First Alert Precision Detection Technology is designed to provide early warning while helping reduce nuisance alarms. The combination smoke and CO detection system uses photoelectric smoke sensing and electrochemical carbon monoxide sensing to help identify two important household hazards.

Wireless Interconnection for Connected Protection

Compatible interconnected alarms communicate so that when one alarm sounds, other compatible connected alarms can sound as well. This helps alert household members to a potential emergency in another part of the home. Compatibility depends on the alarm models and installation configuration.

Voice Alerts with Heads-Up Warnings

Voice alerts provide information about the type and location of a detected hazard, helping occupants understand what the alarm is warning them about. Heads-Up warnings offer an additional layer of information during certain alert conditions.

Battery Backup and Low-Battery Notifications

The SC5 is available in battery-powered and hardwired configurations. Battery-powered models use replaceable lithium batteries, while compatible hardwired models include battery backup to help maintain protection during a power outage. Low-battery notifications help indicate when battery attention is needed.

Compatible with Google Nest Protect

The SC5 is designed to work alongside compatible Google Nest Protect alarms through the Google Home app. This makes it a useful option for households looking to expand or replace compatible components in an existing connected smoke and carbon monoxide alarm system.

Convenient Two-Pack for Multiple Areas

With two alarms in one package, you can plan connected protection for different areas of your home. Follow the manufacturer's installation instructions and applicable local fire-safety requirements to determine the appropriate number and placement of alarms.
