1. Introduction
RA02C is a CO/temperature detector for Netvox Class-A 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.

4. Set up Instruction

On/Off

Power on

Insert batteries. (Users may need a screwdriver to open the cover)

Turn on

Press any function key to turn on the device. After releasing the key, the red and green indicators will flash at the same time to indicate that it turns on successfully.

Press and hold both keys for 5 seconds till the green indicator flashes and then release; Turn off (Restore to factory setting)
LED flashes quickly 20 times.

Power off

Remove Batteries.

1. After 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

Note:

inductance and other energy storage components.

3. Do not power on the device while any function key is pressed, otherwise the device will enter

the engineering test mode.

Network Joining

Turn on the device to search the network.

Never joined the network

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Turn on the device to search the previous network.

Had joined the 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 and Test Key

Press and hold both keys for 5 seconds

Restore to factory setting / Turn off The green indicator flashes 20 times: success The green indicator remains off: fail

Press function key 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

The device is in the network: The buzzer alarms for 5 seconds, the red indicator flashes 5 times,

Press test key once

and sends a report

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

Sleeping Mode The device is on and in the network Low Voltage Warning Low Voltage Threshold
5. Data Report

Sleeping period: Min Interval. When the reportchange exceeds setting value or the state changes, a data report will be sent according to Min Interval.
2.4V

The device will immediately send a version packet report and a data report. Data will be reported by default setting before any configuration.

Default setting: Max Interval = 0x0E10 (3600s) Min Interval = 0x0E10 (3600s) (The voltage is detected every Min Interval by default.) Battery Voltage Change: 0x01 (0.1V)
CO Trigger: The CO concentration is sampled 30 seconds after the device is powered up, when the concentration is higher than 110 ppm, the red indicator light flashes, the buzzer alarms and immediately sends a report (CO alarm bit is 1). If the alarm continues, the report will be sent every 30 seconds. When the concentration drops below 110ppm, the flashing end alarm will be stopped and an alarm will be sent to restore the report.
High Temperature Alarm: After the device is successfully connected to the network, the temperature will be sampled once every 1 minute. When the temperature is higher than 60°C, the buzzer will alarm, the red indicator will flash, and a report will be sent immediately. (The fire alarm bit is 1.) If the alarm continues, the report will be sent every 1 minute. When the temperature below 60°C, the flashing end alarm will be stopped and an alarm will be sent to restore the report. (The fire alarm bit is 0.)

Note: (1) The device report interval will be programmed based on the default firmware. (2) The interval between two reports must be the minimum time. The reported data is decoded by the Netvox LoRaWAN Application Command document and http://cmddoc.netvoxcloud.com/cmddoc

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. 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.
