1. Introduction
R311FB is a vibration alarm device for Netvox ClassA type equipment based on LoRaWAN open protocol. It can count the number of movements or
vibrations of the device and 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.

4. Set up Instruction
On/Off
Power on
Insert batteries.
(users may need a flat blade screwdriver to open); insert two sections of 3V CR2450 button batteries and close the
battery cover.)
Turn on Press any function key till green and red indicator flashes once.
Turn off
(Restore to factory setting) Press and hold both function keys for 5 seconds till green indicator flashes for 20 times.
Power off Remove Batteries.
Note:
1. Remove and insert the battery; the device will memorize previous on/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. Press any function key and insert batteries at the same time; it will enter engineer testing 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
The green indicator remains off: fail
Had joined the network
(not at factory setting)
Turn on the device to search the previous network to join.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Fail to join the network
(when the device is on)
First two mins:wake up every 15 seconds to send request.
After two mins: enter sleeping mode and wake up every 15 minutes to send request.
Note: Suggest to remove batteries if the device is not used to save power.
Suggest to check the device verification information on the gateway with your platform server provider.
Function Key
Press and hold for 5
seconds
Restore to factory setting / Turn off
The green indicator flashes for 20 times: success
The green indicator remains off: fail
Press once The device is in the network: green indicator flashes once and sends a report
The device is not in the network: green indicator remains off

4
Sleeping Mode
The device is on and in the
network
Sleeping period: Min Interval.
When the reportchange exceeds setting value or the state changes: send a data report according to Min Interval.
The device is on but not in
the network
First two mins: wake up every 15 seconds to send request.
After two mins: enter sleeping mode and wake up every 15 minutes to send request.
Note: Suggest to remove batteries if the device is not used.
Suggest to check device verification on gateway.
Low Voltage Warning
Low Voltage 2.4 V
5. Data Report
When the device is turned on, it will immediately send a version package.
Data will be reported once per hour by default setting.
Maximum time: Max Interval
Minimum time: Min Interval (Detect the current voltage value every Min Interval by default setting)
Default reportchange:
batteryvoltagechange ---- 0x01 (0.1V)
Remarks:
1. The device periodically sends data according to the maximum time. The data content is:
R311FB current device status.
2. R311FB device will only report according to the minimum time when the battery voltage changes.
3. The actual data sending cycle depends on real program before shipment.
R311FB vibration alarm:
The device detects sudden movement or vibration, and the quiescent state changes. The device waits for a certain period of time (DeactiveTime) to
enter the quiescent state and counts 1 time for the cumulative number, sends a report of the cumulative number of vibrations, and restarts the
preparation for the next detection. If the vibration continues to occur, the timing of DeactiveTime restarts until it reaches a standstill to count 1 time for
the cumulative number. The count data is not saved when it is powered off.
Can be changed by the gateway to change the device type, active vibration threshold and DeactiveTime.
The Active vibration threshold range is 0x0003-0x00FF (default is 0x0003);
DeactiveTime is 0x01-0xFF (default is 0x05);
R311F DeviceType(1Bytes,0x01_ R311FA,0x02_ R311FB,0x03_ R311FC), the default value is the programming value.
For the analysis of the data reported by the device, refer to the Netvox LoraWAN Application Command document and the

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 change value 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. Tear off the 3M adhesive on the back of the motion detection
counter, and stick the body to the surface of the smooth object
(or motor) (please do not stick to the rough surface to prevent
the device from falling off after a long time)
Notes:

Wipe the surface of the object clean before installation to
avoid dust on the surface of the object and affect the paste
effect of the device.
Do not install the body in a metal shield box or in an
environment surrounded by other electrical equipment to
avoid affecting the wireless transmission of the equipment.
2. When the device detects the sudden movement or
vibration of the item (or the motor), the device status
changes; wait for a period of time (Deactive Time-default
5 seconds, can be modified) after entering the static state,
it is counted to be vibration once, the count is increased by
1. In the mean time, it will send the number of
simultaneous vibrations.
Notes:
(1) After the device vibrates and before it enters the
stationary state, if it continues to vibrate, it is postponed
for 5 seconds until the device enters the stationary state
before counting to 1.
(2) After the device is powered off, the count data is
cleared.
The motion detection counter (R311FB) is suitable for the
following scenarios:
Industrial equipment
Industrial instrument
Medical instruments
Where it is necessary to detect the number of motor runs

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 excessive 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.
