The First Alert CO400 is a Battery Operated Carbon Monoxide Alarm from First Alert with mute button to silence any nuisance alarms.

The First Alert Smart Smoke & CO Alarm and First Alert App experience offer broad Wi-Fi range, easy alarm testing, and a seven-day, low-battery warning to eliminate low-battery chirps.

The First Alert P1010 Atom Battery Powered Micro Design Smoke and Fire Alarm comes with a 10-year battery.

First Alert did replace the detector free of charge (as it did with the battery-powered ones that failed), and the replacement had no similar issues.

The department said on Facebook that the fire started in the electric-car's battery compartment which had not sustained any previous damage ahead of the incident.

Google is ending sales of the Nest Protect smart smoke detector, and partnering with First Alert for a new model.
