1. Introduction R718DA2 is a ball-type two-way vibration sensors of Netvox ClassA type equipment based on LoRaWAN open protocol. The sensor is attached to the detected device with magnet. When the device vibrates, the sensor is triggered. R718DA2 immediately sends the trigger information to the gateway. R718DA2 is compatible with LoRaWAN protocol.
Low power consumption and long battery life Note: Battery life is determined by the sensor reporting frequency and other variables . Please refer to http://www.netvox.com.tw/electric/electric_calc.html On this website, users can find various types of battery life time in different configurations.
4. Set up Instruction On/Off Power on Insert batteries (Users may need a screwdriver to open) Turn on Press and hold the function key for 3 seconds and the green indicator flash once. Turn off (Restore to factory setting) Press and hold the function key for 5 seconds and the green indicator flashes 20 times. Power off Remove Batteries.
The device report interval will be programmed based on the default firmware which may vary. The interval between two reports must be the minimum time. Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://cmddoc.netvoxcloud.com/cmddoc to resolve uplink data.

7. 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.
c. The voltage of the circuit should be ≧3.3, indicating successful activation. Brand Load Resistance Activation Time Activation Current 165 Ω NHTONE 5 minutes 20mA 67 Ω RAMWAY 8 minutes 50mA 67 Ω 8 minutes 50mA 67 Ω SAFT 8 minutes 50mA Note: If you buy batteries from other than the above four manufacturers, then the battery activation time, activation current, and...
