Wireless Networked Smoke Detector September 29, 2014
Reviewer: JP from El Dorado Hills, CA United States  
This is the second set I have purchased. I Feel much safer knowing that if one detector goes off, they all go off.  No one will sleep through 7 smoke and carbon detectors. I have 2 hardwired and 5 wireless remote.
