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.

3. Main Features

Apply SX1276 wireless communication module

2 section 3V CR2450 button battery powered

Vibration and battery voltage detection

Compatible with LoRaWANTM Class A

Frequency hopping spread spectrum technology

Configuration parameters can be configured through third-party software platforms, data can be read

and alarms can be set via SMS text and email (optional)

Available third-party platform: Actility / ThingPark, TTN, MyDevices/Cayenne

Improved power management for longer battery life

Battery Life:

⁻Please refer to web: http://www.netvox.com.tw/electric/electric_calc.html

⁻At this website, users can find battery life time for variety models at different configurations.

1. Actual range may vary depending on environment.

2. Battery life is determined by sensor reporting frequency and other variables.

4. Set up Instruction

On/Off

Power on Insert two sections of 3V CR2450 button batteries and close the battery cover

Turn on Press any function key till the green and red indicator flash once.

Turn off

(Restore to factory setting)

Press and hold the function key for 5 seconds till the green indicator flashes for

20 times.

Power off Remove Batteries.

Note:

1. Remove and insert the battery; the device memorizes 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

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 device verification on gateway.

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: the green indicator flashes once and sends a report

The device is not in the network: the green indicator remains off

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

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.
