1. Introduction R311A is a long-distance window/door sensor based on the LoRaWAN open protocol (Class A). LoRa Wireless Technology: LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance.

The network operation is as following: (1) If R311A had never joined any network or at factory setting mode, turn on the device; it will search an available LoRa network to join. The green indicator will stay on for 5 seconds to show it joins into the network, otherwise, the green indicator does not work.
(B) When it is not in the network → R311A will enter sleeping mode and wake up every 15 seconds to search a network to join in the first two minutes. After two minutes, it will wake up every 15 minutes to request to join the network.
7. Low Voltage Alarming The operating voltage threshold is 2.4V. If the voltage is lower than 2.4V, R311A will send a low-power report to the Lora network. 8. MyDevices Dashboard Interface Demonstration 9.
