Introduction

RA0701_R72601_RA0701Y is a ClassA type device based on the LoRaWAN protocol.
The RA0701_R72601_RA0701Y data can be sent to the corresponding gateway via externally connecting the CO detector.

LoRa Wireless Technology:
Lora is a wireless communication technology dedicated to long-distance and low power consumption. Compared with other communication methods, the LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely used in long-distance, low-data wireless communications. Examples, 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.

Set up Instruction

On/Off

**** Power On| RA0701 and RA0701Y are connected to a DC 12V adapter for power on.
R72601 applies solar power and rechargeable lithium batteries.
---|---
Turn On| Connect with power on to turn on
Restore to Factory Setting| Press and hold the function key for 5 seconds, and the green indicator flashes 20 times.
Power Off| Disconnect from the power supply
Note| 1. The engineering test requires writing the engineering testing software separately.
2. The interval between on and off 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.
The green indicator keeps 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 the previous network. The green indicator keeps on for 5 seconds: success. The green indicator remains off: fail.
Fail to Join the Network| Suggest checking the device registration information on the gateway or consulting your platform service provider if the device fails to join the network.

Low Voltage Threshold

Function Key

Press and Hold 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 the device sends a data report (It would take 35 seconds for the sensor to sample and process the collected value after pressing the button) The device is not in the network: the green indicator remains off

Data Report

After power is on, the device will immediately send a version packet report and data.
The device sends data according to the default configuration before any other configuration.
ReportMaxTime:
RA0701 and RA0701Y are 180s,
R72601 is 900s (subject to original setting)
ReportMinTime: 30s
ReportType count: 1
ReportChange: 0

• ReportChange is not supported by RA0701_R72601_RA0701Y (Invalid configuration).
• The value of the ReportMaxTime should be greater than ReportType count *ReportMinTime+10

Note:

1. The device also supports the TxPeriod cycle configuration instructions of Cayenne. Therefore, the device can perform the report according to the TxPeriod cycle. The particular report cycle is ReportMaxTime or TxPeriod depending on which report cycle was configured last time.
2. It would take 35 seconds for the sensor to sample and process the collected value after pressing the button, please be patient.
3. Data pocket: CO
   The device reported data parsing please refer to the Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index

3.  The RA0701Y product is waterproof and can be placed outdoors after the network joining is completed.
   (1) In the position to be installed, loosen the bottom U-shaped screw of the RA0701Y and the mating washer nut, and fix the U-shaped screw through the appropriate size cylinder on the RA0701Y fixed strut piece. Install the washer nut in order, and lock the nut till RA0701Y body is stable and does not shake.
   (2) Loosen the M5 nut at the bottom of the RA0710Y matte and take the matte together with the screw.
   (3) Insert the power DC plug from the center through the hole of the RA0701Y bottom cover, insert it into the RA0701Y DC socket, and then return the mating screw to the original position and lock the M5 nut tight.

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 a dusty or dirty environment. It might damage its detachable parts and electronic components.
• Do not store the device under excessive heat conditions. 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 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.
