1. Introduction R718J2 is a ClassA external 2-way dry contact device based on LoRaWAN open protocol of Netvox. It can externally connect various switches, buttons, relays and reed switch output. It can detect the closing or disconnecting signal of dry contact and is compatible with LoRaWAN protocol.
3. Main Feature ⚫ Apply SX1276 wireless communication module ⚫ 2 ER14505 lithium batteries (3.6V / section) parallel power supply ⚫ Dry contact detection ⚫ The base is attached with a magnet that can be attached to a ferromagnetic material object ⚫...
4.2 Join into the Network To join the device into LoRa network to communicate with LoRa gateway. The network operation is as following: (1) If the device had never joined any network, 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 will be off.

(B) When it is not in the network → R718J2 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.
8. Installation 1. The dry contact sensor (R718J2) has a built-in magnet (as 2. After the dry contact sensor detects the change of the dry Figure 1 below), which can be attached to the surface of an contact state, it will report the data immediately.
9. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.
10. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: • Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case the device is wet, please dry it completely.
