1. Introduction
This device is an alarm device for 2-way leak detection. When the water sensor detects a leak, it will
send an alarm message to the gateway. When the water sensor detects that there is no water leak
again, it will send a back to normal status message to the gateway, which uses the SX1276 wireless
communication module.
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
4.1 Power on and Turn on / off
(1) Power on: Insert batteries: open the battery cover; insert two sections of 3.6V ER14505 AA
batteries and close the battery cover.
(2) Turn on: if the device had never joined in any network or at factory setting mode, after
powering on, the device is at off mode by default setting. Press and hold function key for 3 seconds
till the green indicator flashes once and release to turn on device.
(3) Turn off: Press and hold function key for 5 seconds till the green indicator flashes quickly and
release. The green indicator will flash 20 times to show that the device is turned off.
Note:
1. The interval between shutting down twice or power off/on is suggested to be about 10 seconds to
avoid the interference of capacitor inductance and other energy storage components.
2. Do not press function key and insert batteries in the same time, otherwise, it will enter engineer
testing mode.
3. Once the battery is removed, the device is at off mode by default setting.
4. Turn off operation is same with “Restore to Factory Setting” operation.
4.2 Join Into LoRa Network
To join the device into LoRa network to communicate with LoRa gateway.
The network operation is as following:
(1) If the device had never joined any network, turn on the device; it will search an available LoRa
network to join. The green indicator will stay on for 5 seconds to show it joins into the network,
otherwise, the green indicator will be off.
(2) If R718WA2 had been joined into a LoRa network, remove and insert the batteries; it will repeat
step (1).
4.3 Function Key
(1) Press and hold function key for 5 seconds to reset to factory setting. After restoring to
factory setting successfully, the green indicator will flashes quickly 20 times.
(2) Press function key to turn on the device which is in the network and the green indicator will flash
once and the device will send a data report.

4.4 Data Report
When the device is turned on, it will immediately send a version package.
And a data carrying water leakage status and battery voltage report.
Data will be reported once per hour by default setting.
Maximum time: 3600s
Minimum time: 3600s (Detect the current voltage value every 3600s by default setting)
Default reportchange:
Battery ---- 0x01 (0.1V)
Trigger:
When the leak sensor is immersed in water, it will immediately issue a report, leaking status:1.
When the leak sensor is out of the immersion state, a report is issued immediately, no water leakage
status: 0.
Note:
The device send data cycle depends on real burning configuration.
The interval between two reports must be the minimum interval.
Data report configuration and sending period are as following:
5. Restore to Factory Setting
R718WA2 saves data including network key information, configuration information, etc. To restore
to factory setting, users need to execute below operations.
1. Press and hold function key for 5 seconds till the green indicator flashes and then release; LED
flashes quickly 20 times.
2. R718WA2 is at off mode by default setting after restoring to factory setting.
Note: The device operation of turning off is the same as the “Restore Factory Settings” operation.

6. Sleeping Mode
R718WA2 is designed to enter sleeping mode for power-saving in some situations:
(A) While the device is in the network → the sleeping period is Min Interval. (During this
period, if the reportchange is larger than setting value, it will wake up and send a data report).
(B) When it is not in the network → R718WA2 will enter sleeping mode and wake up every
15 seconds to search a network to join in the first two minutes. After two minutes, it will wake
up every 15 minutes to request to join the network.
If it’s at (B) status, to prevent this unwanted power consumption, we recommend that users
remove the batteries to power off the device.
7. Low Voltage Alarming
The operating voltage threshold is 3.2V. If the battery voltage is lower than 3.2V, R718WA2 will
send a low-power warning to the LoRa network.
8. Installation
This product comes with waterproof function. When using it, the back of it can be adsorbed on the
iron surface, or the two ends can be fixed to the wall with screws.
Note: To install the battery, use a screwdriver or similar tool to assist in opening the battery cover.
9. 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.
