## Description

Review: Works great - Worked perfectly, replaced a broken sensor
Review: Works for sure with ADT or Vivint security systems - I had a few bad window sensors. These said they were compatible with Vivint and ADT security systems, so I gave it a try because they were cheaper than from the Vivint or ADT app. The price had me worried. But THEY WORKED exactly as the Vivint and the ADT sold ones. These will be purchased by me again if anymore of our sensors go bad. Easy to connect and set up too.

- Suitable for 22-28 AWG wirs
- Reliable quality with white case
