Installed the IO 102-51 NZ black magnetic contact detector on a commercial storefront door. The compact size made fitting it into a tight frame easy, and the performance has been consistent with no false alarms. Compatibility with our existing alarm system was straightforward after checking the specs carefully.

What should be reviewed in the manufacturer documentation?
The administration's response:
Review the full model number, dimensional data, rating tables, material notes, mounting information, and any listed connection details. The short product title is helpful for search, but the datasheet should be the main reference before ordering.
