Google Nest Protect Wired Smoke and Carbon Monoxide Detector

This Protect Wired Smoke and Carbon Monoxide Detector from Nest is the ultimate smoke alarm for your home. Re-designed from the inside out, it has an industrial-grade smoke sensor, can be silenced from your phone, tests itself automatically and lasts for up to 10 years. Just like the original Nest Protect, it also tells you what's wrong so you know what to do and where to go and can even conveniently alert your phone in the event of an unforeseen event. Its super-efficient sensor detects both fast and slow burning fires.
