Google Nest Protect Wireless Smoke and Carbon Monoxide Alarm, 2nd Gen (S3004PWBUS)

Protect occupants and property with the Google Nest Protect wireless smoke and carbon monoxide alarm — a combination detector built for reliable, everyday security and monitoring. This Nest Protect uses a split-spectrum sensor to spot both smoldering and fast-burning fires while its electrochemical CO sensor provides continuous carbon monoxide monitoring with a 10-year sensor life. When danger is detected the unit speaks the location and sounds an 85 dB alarm, then sends Heads-Up alerts to mobile devices so on-site staff or remote managers know what and where the issue is. Battery-powered with included long-life AA batteries and wireless connectivity, Nest Protect installs easily in homes, rentals, or commercial spaces and integrates into broader safety plans. Automated Sound Check and regular self-tests help ensure consistent performance and reduce manual maintenance. Ideal for property managers, contractors, and security teams looking to upgrade smoke/CO detection as part of a layered security and surveillance strategy. Add Google Nest Protect to hallways, living areas, and utility rooms to improve emergency response and peace of mind.
