Description
The ADC-FLEX-100 Flex IO sensor is a cellular-based monitoring device designed to track and protect property and assets in locations where traditional connectivity is not available. It can be used with an included magnet to monitor doors, gates, and entry points, and also supports integration with third-party devices using its input and output capabilities.
 
Key Features
Detect open/close using magnetic reed switch
Detect state change from third-party devices using loop input
Control third-party devices using relay output (requires external power)
Supports multiple mounting options (screws or zip ties)
Optional tamper detection (mount and battery door)
