1. Introduction
R718PA4is a long-range wireless occupancy detection device for Netvox Class A type devices based on LoRaWAN open protocol.
The R718PA4 can be connected to a hydrogen sulfide sensor with RS485 to report the concentration of hydrogen sulfide collected by the device to the
corresponding platform. 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.

4.Set up Instruction
On/Off
Power on DC12V adapter
Turn on Press and hold the function key for 3 seconds till the green indicator flashes once.
Turn off
(Restore to factory setting) Press and hold the function key for 5 seconds till the green indicator flashes for 20 times.
Power off Remove DC12V adapter.
Note:
1. At 1st to 5th second after power on, the device will be in engineering test mode.
2. Remove and supply the power; the device is at off state by default. Need to be turned on to use.
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 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
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
(when the device is on)
First two mins: wake up every 15 seconds to send request.
After two mins: enter sleeping mode and wake up every 15 minutes to send request.
Note: Suggest to remove batteries if the device is not used to save power.
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 for 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
5. Data Report
The device will immediately send a version package report and a report data with temperature and humidity and voltage values.
The device sends data in the default configuration before any configuration is done.
Maximum time: Max Interval
Note:
The real data sending cycle is programmed before shipment. There is no minimum time supported.
R718PA4 defaults Max Interval = 60min.
R718PA4 reports the hydrogen sulfide H2S concentration value.
The data parsing reported by the device is referenced by the Netvox LoraWAN Application Command document and http://www.netvox.com.cn:8888/page/index

1. The device has a built-in magnet (as shown
below). It can be attached to the surface of an iron
object when it is installed, which is convenient and
quick. 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 in -
two screws in the middle (purchased by users).
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.
2. The device periodically reports the data
according to Max Time. The default Max Time
is 1 hour. Note: Max Time can be modified by
the downlink command, but it is not
recommended to set this time too small to avoid
excessive battery drain.
3. The device can be used in scenarios such as:
Sewer
Pig farm
Chemical plant
Wastewater treatment plant
Exploration drilling channel

7.Important Maintenance Instruction
Your device is a product of superior design and craftsmanship and should be used with care. The following suggestions will help you use the warranty
service effectively.
• Keep the equipment dry. Rain, moisture, and various liquids or moisture 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 can damage its detachable parts and electronic components.
• Do not store in excessive heat. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
• Do not store in a 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. Rough handling of equipment can destroy internal circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not apply with paint. Smudges can block debris in detachable parts and affect normal operation.
• Do not throw the battery into a fire to prevent the battery from exploding. Damaged batteries may also explode.
All of the above suggestions apply equally to your device, battery and accessories. If any device is not working properly.
Please take it to the nearest authorized service facility for repair.
