1. Introduction

The R312 is a doorbell button device for Netvox ClassA type devices based on the LoRaWAN open

protocol and is compatible with the LoRaWAN protocol.

LoRa Wireless Technology:

LoRa is a wireless communication technology famous for its long-distance transmission and low

power consumption. Compared with other communication methods, LoRa spread spectrum

modulation technique greatly extend the communication distance. It can be widely used in any use

case that requires long-distance and low-data wireless communications. For example, automatic

meter reading, building automation equipment, wireless security systems, industrial monitoring. It

has features like small size, low power consumption, long transmission distance, strong

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.

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 various 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 batteries (users may need a screwdriver to open)

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

cover.

Note: Require 2 button batteries to supply power at the same time.

Turn on Press any function key and indicator flashes once meaning it is turned on

successfully.

Turn off

(Restore to factory setting)

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

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. If 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.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Had joined the network

(not restore to the factory setting)

Turn on the device to search the previous network.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Fail to join the network Suggest to check the device verification information on the gateway or

consult your platform server provider.

Function Key

Press and hold for 5 seconds

Restore to factory setting / Turn off

The green indicator flashes 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

Press doorbell button

Trigger the doorbell alarm

Note: Users can configure the button pressing time to send alarm by

command

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.

Low Voltage Warning

Low Voltage 2.4V

per Max Interval

The device will immediately send a version packet report along with an uplink packet including

doorbell alarm.

The device sends data in the default configuration before any configuration is done.

Default setting

Maximum time: 3600s

Minimum time: 3600s

BatteryChange: 0x01 (0.1V)

Doorbell button trigger:

Press the doorbell button and immediately send a report.

R312 was pressed, Alarm=1

R312 was not pressed, Alarm=0

Note:

1. The actual data sending cycle of the device is subject to the programming configuration

before shipment.

2. The interval between two reports must be the minimum time

The data report can be decoded by the Netvox LoraWAN Application Command

document and http://www.netvox.com.cn:8888/page/index
