1. Introduction
R718DB2 is a 2-way long-range wireless spring-loaded vibration device for Netvox ClassA-type devices based on the
LoRaWAN open protocol and is compatible with the 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.

The device will immediately send a version packet report and the vibration report data.
The device sends data in the default configuration before any configuration is done.
Default setting:
Max Interval: 0x0E10 (3600s)
Min Interval: 0x0E10 (3600s)
BatteryVoltageChange: 0x01 (0.1V)
R718DB2 Trigger:
When the sensor senses the vibration and the spring deforms, an alarm message will be reported.
The vibration is “1”.
No vibration is “0”.
The vibration Restore Configuration
The Restore function is used to send the final static status of the device.
(Please refer to the configuration command format below.)
Restore = 0, no data will be sent when the device is rest.
The data is sent with the next report.
Restore = 1, the data will be sent with a vibration bit-- 0 after the device is rest for 5 seconds.
Note:
1. The function of Restore is supported by the firmware version after 2020/05/18 version.
2. The device report interval will be programmed based on the default firmware which may vary.
3. The interval between two reports must be the minimum time.

Tips
1. Battery Voltage:
The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage.
Battery=0xA0, binary=1010 0000, if bit 7= 1, it means low voltage.
The actual voltage is 0010 0000 = 0x20 = 32, 32*0.1v =3.2v
2. Version Packet:
When Report Type=0x00 is the version packet, such as 013D000A0B202005200000, the firmware version is 2020.05.20
3. Data Packet:
When Report Type=0x01 is data packet.

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
This product comes with waterproof function. It can be attached to the iron surface, or the two ends can be fixed to the wall with
screws.
1. The figure shows the vibration sensor (R718DB2)
applied to the scene of the mousetrap in the restaurant.
It can also be applied to the following scenarios:
Restaurant (rat)
Shopping mall supermarket (rat)
Engine room (rat)
When it is necessary to detect whether the object is
vibrating or moved.
2. Fix the vibration sensor of the vibration sensor on the
object that needs to be detected whether it is vibrating
(Take the mousetrap as a picture, as shown below).
3. When the sensor senses the vibration and the spring deforms, an
alarm message will be reported.
The vibration is “1”.
No vibration is “0”.

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
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 various liquids or moisture may contain minerals that can corrode electronic
circuits. 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 or shake 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.
