1. Introduction
The R311FA is a Wireless Activity Detection Sensor for Netvox ClassA type devices based on the
LoRaWAN open protocol and is compatible with the LoRaWAN protocol.
When the device detects movement or vibration, it immediately triggers an alarm.
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.

5. Data Report
The device will immediately send a version packet report along with an uplink packet including vibration
status and battery voltage.
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
BatteryChange: 0x01 (0.1V)
ActiveThreshold: 0x0003 (Threshold range: 0x0003-0x00FF, 0x03 is the most sensitive)
Deactivetime: 0x05 (Deactive time Range: 0x01-0xFF)
ActiveThreshold:
Active Threshold = Critical value ÷ 9.8 ÷ 0.0625
*The gravitational acceleration at standard atmospheric pressure is 9.8 m/s2
*The scale factor of the threshold is 62.5 mg
R311FA vibration alarm:
The device detects a sudden movement or vibration, change of the quiescent state, and it will
immediately send a report. After the vibration alarm, the device waits for DeactiveTime to enter the
quiescent state before starting the next detection. If the vibration continues to occur during this process,
the timing restarts until it enters the quiescent state.
R311FX Series DeviceType:
R311FA 0x01; R311FB 0x02; R311FC 0x03
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
http://www.netvox.com.cn:8888/page/index to resolve uplink data.

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.Remove the 3M adhesive on the back of the
Activity Detection Sensor and attach the body to
the surface of a smooth object (please do not stick
it to a rough surface to prevent the device from
falling off after a long time use).
Note
：
Wipe the surface clean before installation to
avoid dust on the surface to affect the
adhesion of the device.
Do not install the device in a metal shielded
box or other electrical equipment around it to
avoid affecting the wireless transmission of
the device.
2. The device detects a sudden movement or
vibration, and it will immediately sends a report.
After the vibration alarm, the device waits for a
certain period of time (DeactiveTime- default : 5
seconds,can be modified) to enter the quiescent
state before starting the next detection.
Note
：
If the vibration continues to occur during this
process(quiescent state),than it will delay 5
seconds until it enters the quiescent state.
When the vibration alarm is generated, the
alarm bit of the data is "1",quiescent state bit of
the data is "0"
Activity Detection Sensor (R311FA) is suitable for
the following scenarios:
Valuables (Painting, Safe)
Industrial Equipment
Industrial Instrument
Medical Instruments
When it necessary to detect a possibility of the
valuables are moved and the motor running.

8. 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.
