Purchased a while back and never ended up using. Kit is brand new and currently sold out by manufacturer. Designed for Kidde smoke alarm and likely will not work with other brands
We put together this simple solution for smart monitoring of your existing smoke alarms to make your life easier and safer. Just connect the 3 pigtail wires to the last smoke alarm in series, add the Zooz relay to your Z-Wave hub, and receive status notifications in the app whenever any of your smoke alarms is triggered. Make sure your detectors are interconnected.
