First Alert, a fire-safety brand owned by Resideo, and Google Home have announced a new life-safety collaboration: The new First Alert Smart Smoke & Carbon Monoxide (CO) Alarm that is compatible with the Nest Protect Smart Smoke & CO Alarm.
The global companies point out that through this collaboration existing Nest users can add the Smart Smoke & CO Alarm in the Google Home app to extend their existing coverage or replace an expiring Nest Alarm for seamless coverage.
“At Google Home we’re deeply committed to building a platform that makes it easy to set up, control and automate all of your smart home devices in one place,” says Anish Kattukaran, chief product officer at Google Home & Nest.
“The Nest Protect has been one of our most beloved devices and we are excited to be partnering with established industry leaders like First Alert so users can manage more of their safety devices together, for a safer and more protected home.”
First Alert Connects with Nest Protect for Unified Responses
The smart, two-in-one alarm can connect with Nest Protect Smoke & CO Alarms, and if one alarm sounds, all connected and compatible alarms will alert families to the danger, whether at home or away. The new smart alarm also offers safety checkups, safety alerts, and the ability to silence alarms within both the First Alert and Google Home apps.

The Future of Digital Lighting & Control
As a custom integrator, lighting is in demand. Effective communication, education and showcasing the value proposition of LED light fixtures in conjunction with integrative control systems are the keys to overcoming challenges and closing sales in this specialized market.

Photoelectric Sensors Provide Precision Detection
A key feature of First Alert’s smart, two-in-one alarm is Precision Detection, which uses photoelectric sensing technology to provide early warning and detection of smoke and fire. The technology is said to address modern home construction and design trends, as fires burn hotter and faster in homes built with more open spaces and are furnished with lighter, synthetic materials.
The Smart Smoke & CO Alarm and First Alert App experience offer broad Wi-Fi range, alarm testing options, and a seven-day, low-battery warning to eliminate low-battery chirps. The new alarm also provides:
- Critical Safety Alerts. Voice alerts describe the type and location of the emergency within the home and mobile alerts provide awareness when away from the home.
- Heads-up Early Warning. Voice and app alerts provide an early indicator to an emerging smoke or CO event before it becomes an emergency, and the alarm can be silenced via the First Alert or Google Home apps.
- Interconnected System. The alarm’s wired and wireless interconnectivity ensures that when one alarm sounds, all compatible alarms will sound to notify the home of the smoke or CO emergency. This exclusive synchronized alert system provides comprehensive coverage with compatible alarms, and enables a non-connected First Alert smoke or CO alarm to signal with the First Alert app.
The Smart Smoke & CO Alarm will be available in hardwire or battery powered options in the coming months through U.S. and Canadian dealers for $129.99 (projected U.S. MSRP). It also will be available through Resideo’s professional distribution partners, including the electrical channel and builder partners.
