2GIG Recessed Door Contact
Make your contact invisible. The 2GIG-DW20R-345 hides inside the door or window frame for a clean look while providing supervised, reliable protection on 345 MHz. It uses a rare-earth magnet, long-life CR2032 coin cell, and offers strong open-air range up to ~450 ft—ideal for front doors, French doors, and casements. An encrypted eSeries version is also available.

- Pro drilling & alignment: We bore the correct 11/16″ holes, set proper depths, and align magnet/sensor for dependable trips.
- Discreet finish: Hardware disappears once the door is closed—great for premium trim and painted finishes.
- Clean programming: We enroll and label the zone, verify supervision/tamper/low-battery reporting, and test RF range.
