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.
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.
Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation
equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption,
transmission distance, anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and
gateways from different manufacturers.

Notes :
1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not
collect data.
2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value,
the device reports according to MinTime interval. If the data variation is not greater than the last data reported, the device
reports according to MaxTime interval.
3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up
frequently and the battery will be drained soon.
4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another
cycle of MinTime/MaxTime calculation is started.

6. Installation
When installing the vibration sensor, pay attention to the fact that the direction of the vibration and the long side of the sensor on
the same as below figure.
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. This lithium chloride
layer prevents rapid self-discharge caused by continuous reaction between lithium and thionyl chloride, but battery passivation
may also lead to voltage delay when the batteries are put into operation, and our devices may not work correctly in this situation.
As a result, please make sure to source batteries from reliable vendors, and it is suggested that if the storage period is more
than one month from the date of battery production, all the batteries should be activated.
If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.
ER14505 Battery Passivation:
7.1 To determine whether a battery requires activation
Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit.
If the voltage is below 3.3V, it means the battery requires activation.
7.2 How to activate the battery
a. Connect a battery to a resistor in parallel
b. Keep the connection for 5~8 minutes

10
c. The voltage of the circuit should be ≧3.3, indicating successful activation.
Brand Load Resistance Activation Time Activation Current
NHTONE 165 Ω 5 minutes 20mA
RAMWAY 67 Ω 8 minutes 50mA
EVE 67 Ω 8 minutes 50mA
SAFT 67 Ω 8 minutes 50mA
Note:
If you buy batteries from other than the above four manufacturers, then the battery activation time, activation current, and
required load resistance shall be mainly subject to the announcement of each manufacturer.
8. Important Maintenance Instruction
Your device is a product of superior design and craftsmanship and should be used with care. The following suggestions will help
you use the warranty service effectively.
•Keep the equipment dry. Rain, moisture,and variousliquids ormoisture may containminerals that can corrodeelectroniccircuits.
In case the device is wet, please dry it completely.
•Do not use or store in dusty or dirty areas. This can damage its detachable parts and electronic components.
•Do not store in excessive heat. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt
some plastic parts.
•Do not store in a cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside, which will
destroy the board.
•Do not throw,knock orshake the device.Rough handling of equipment can destroy internal circuit boards and delicate structures.
•Do not wash with strong chemicals, detergents or strong detergents.
•Do not apply with paint. Smudges can block debris in detachable parts and affect normal operation.
•Do not throw the battery into a fire to prevent the battery from exploding. Damaged batteries may also explode.
All of the above suggestions apply equally to your device, battery and accessories.
If any device is not working properly, please take it to the nearest authorized service facility for repair.
