1. Introduction
The R311CAis a dry contact detection device for Netvox ClassA type devices based on the LoRaWAN open protocol and is
compatible with LoRaWAN protocol. When any dry contact of R311CA detects a change, R311CAwill send a message to the
gateway.
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 and 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 need a flat blade screwdriver to open)
Turn on Press any function key till green and red indicator flashes once.
Turn off (Restore to original setting) Press and hold the function key for 5 seconds till the 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. Press any function key and insert batteries at the same time; it will enter engineer testing
mode.
3. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor
inductance and other energy storage components.
Network Joining
Never join 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 in the original setting)
Turn on the device to search for 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 Suggest checking device verification on the gateway or consulting your platform service
provider if the device fails to join the network.
Function Key
Press two function keys for 5
seconds
Restore to the original setting / Turn off
The green indicator flashes 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
Low Voltage Warning
Low Voltage 2.4V
Sleeping Mode
The device is turn on and join in the
network
Sleeping period: Min Interval.
When reportchange exceeds the set value: send data packets according to Min Interval.
