4. Functionality
The NV-R718TB functions as a wireless interface that detects the open or closed state of two independent dry contact inputs. Each input can be connected to external devices such as mechanical switches, magnetic door sensors, relay outputs, or push buttons. When a contact state changes, the device records the event and transmits the updated status via LoRaWAN to a network gateway.
The device can operate in two primary modes:
1. Event-Driven Mode: Transmits data immediately upon a change in contact state.
2. Periodic Reporting Mode: Sends status updates at predefined intervals, even if no change occurs.
This dual-mode operation ensures both real-time responsiveness and periodic verification of system integrity. The NV-R718TB is ideal for applications such as:
- Door/window open/close monitoring
- Equipment status detection (on/off)
- Alarm system integration
- Remote push button triggering
- Industrial process monitoring
- Smart building automation
The device communicates with a LoRaWAN gateway, which forwards data to a network server or cloud platform for visualization, logging, and control. Configuration parameters such as reporting interval, input logic type, and transmission settings can be adjusted via downlink commands or configuration tools provided by the manufacturer.
