Individual Sensors, Lower Cost
Rather than committing to the full alarm kit upfront, individual door, window, and motion sensors let you expand an existing D3D system or start with just the highest-priority entry point.
Pairs With Your Existing Hub
These sensors and the siren are designed to pair with the D3D ZX-G12 alarm hub, so they work as add-ons if you already have the base system.
Where to Start
Prioritizing your first purchase
Highest Priority: Main Entry Door
If buying individually, start with a door sensor on your main entry point, then add a motion sensor for a central hallway.
Note on the Full Hub
