Introduction
R718PA1 is a Class A device based on the LoRaWANTM protocol of Netvox and is
compatible with the LoRaWAN protocol.
R718PA1 can be connected to a corresponding carbon monoxide sensor (RS485) to
report the concentration of carbon monoxide collected by the device to the
corresponding gateway. The device is compatible with the LoRaWAN protocol.
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.

Set Up Instruction
On/Off
| Power on | DCl2V adapter |
|---|---|
| Turn on | DCl2V power supply, the green indicator flashing once means turn on |
successfully.
Turn of (Restore to factory setting)| Press and hold the function key for 5
seconds till the green indicator flashes 20 times.
Power off| Remove DC I2V adapter.
Note:| I. The first 5 seconds after power on. the device will be in
engineering test mode.
2. 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 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
(Not restore to the factory setting)| 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| 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: the green indicator flashes once and
sends a report
The device is not in the network: the green indicator remains off
Data Report
The device will send a version package report immediately after power-on. Then, it will send a report data with the concentration of carbon monoxide after it is powered on for 20s.
The device sends data according to the default configuration before any other configuring.
Default setting:
MaxTime: Max Interval = 3min = 180s
MinTime: The MinTime configuration is not available.
*But the software has restriction, MinTime must be configured a number greater than 0.
Note:
- The cycle of the device sending the data report is according to the default.
- R718PA1 reports the concentration of carbon monoxide.
Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index to resolve uplink data.

Installation
-
R718PA1 has a built-in magnet (as the figure below). It can be attached to the surface of an iron object conveniently and quickly when it is installed.
In order to make the device installation more secure, use screws (purchased) to fix the device to the wall or other surface (such as the installation diagram). The device is screwed by two screws in the middle (purchased by users). -
The device periodically reports the data according to Max Time. The default Max Time is 3min.
Note:
Do not install the device in a metal shielded box or in an environment with other electrical equipment around it to avoid affecting the wireless transmission of the device.
Note: Max Time can be modified by the downlink command, but it is not recommended to set this time too short. -
The device can be used in scenarios such as:
- Boiler room
- Parking lot
- Gas water heater
- Mine environment monitoring
Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
- Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case the device is wet, please dry it completely.
- Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
- Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
- Do not store in excessive cold place. 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. Treating equipment roughly can destroy internal circuit boards and delicate structures.
- Do not wash with strong chemicals, detergents or strong detergents.
- Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
- Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.
All the above suggestions apply equally to your device, batteries and accessories. If any device is not operating properly. Please take it to the nearest authorized service facility for repairing.
