• You could replace them as needed. Usually to stay in code though you’ll want them all working together (you shouldn’t have some detectors running off interconnect and another batch using WiFi like the protects do — usually all or nothing).

• Yes, you can replace your existing smoke detectors with a Nest Protect, one at a time as they can work independently. But if you want to have an interconnected system of smoke alarms in your home, you can consider replacing them all with Nest Protects and control them using the Nest app. You can learn more about the benefits of having interconnected Nest Protects in your home here: https://support.google.com/googlenest/answer/9244978
