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.

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/s 2
- 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 de vice waits for De active Time to enter the quiescent state before starting the next detection. If the vibration
continues to occur during this process,the timing restarts unit it enters the quiescent state. - R311F X Series DeviceType:

- Example for MinTime/MaxTime logic:
Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V
Note:
MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BtteryVoltageChange value. - Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.
- Example#3 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.
Notes:
- The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.
- 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. - 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.
- 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.
Installation
- 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.
- 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.

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.
