It will simply operate independently of any other smoke detectors. If one of your existing detectors sounds an alarm, your Nest Protect won't sound an alarm (unless it also detects smoke) and vice versa.</P> Sat, 12 Mar 2022 17:14:48 GMT https://www.googlenestcommunity.com/t5/Nest-Protect/Smoke-detector/m-p/121969#M2553 David_K 2022-03-12T17:14:48Z
