1. Introduction
R718DB is identified as a LoRaWAN ClassA device with a spring-loaded vibration sensor and 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.

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.
Note:
1. Remove and insert the battery; the device is at off state by default.
2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor
inductance and other energy storage components.
3. For the first 5 second after powering on, the device will be in engineering test mode.
Network Joining
Never joined the network
Turn on the device to search the network to join.
The green indicator stays on for 5 seconds: success

5. Data Report
Data report configuration and sending period are as following:
Min Interval
(Unit:second)
Max Interval
(Unit:second) Reportable Change Current Change≥ Reportable Change
Current Change＜
Reportable Change
Any number between
1~65535
Any number between
1~65535 Can not be 0 Report per Min Interval
Report
per Max Interval
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:
MaxTime: Max Interval = 60 min = 3600s
MinTime: Min Interval = 60 min = 3600s
BatteryVoltageChange: 0x01 (0.1V)
R718DB trigger:
When any way of the sensor senses the vibration and the spring deforms, an alarm message willbe 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:
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

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
1. The device has a built-in magnet.
When installed, it can be attached to the surface of an
object with iron which is convenient and quick.
To make the installation more secure, use screws
(purchased) to secure the unit to a wall or other surface
Note:
Do not install the device in a metal shielded box or in an
environment with other electrical equipment around it to
avoid affecting the wireless transmission of the device.
2. Fix the vibration sensor of the vibration sensor on the
object that needs to be detected whether it is vibrating
(here, take the mousetrap as a picture.)
Videolink:Mouse trap
3.The figure shows the vibration sensor (R718DB)
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.
4. When the vibration sensor detects a vibration, it
immediately sends an "alarm" message.
When the device reports data periodically, it restores
the "normal" status and sends "normal" status
information. Moreover, enable the Restore function
and the “normal” status will be sent after the device
stops for 5 seconds.
Note:
The shaking alarm bit is “1”.
The static and non-shaking alarm bit is “0”.

7. Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the device dry. Rain, moisture, or any liquid, might contain minerals and thus corrode electronic circuits. If the device gets
wet, please dry it completely.
• Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and electronic components.
• Do not store the device under excessive heat condition. High temperature can shorten the life of electronic devices, destroy
batteries, and deform or melt some plastic parts.
• Do not store the device in places that are too cold. 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 clean the device with strong chemicals, detergents or strong detergents.
• Do not apply the device with paint. Smudges might block in the device and affect the operation.
• Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.
All of the above applies to your device, battery and accessories. If any device is not working properly, please take it to the
nearest authorized service facility for repair.
