1. Introduction
R718F2 is a long-distance door Sensor based on the LoRaWAN open protocol (ClassA). The device is equipped with 2-gang
reed sensors, The reed switch is on (conducting) within the magnetic range, and is off (nonconducting) when it's out of the
magnetic range. The module can detect the closing and opening signals so that the state of the door window status can be
detected.
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.

1. Battery Voltage:
The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage.
Battery=0xA0, binary=1010 0000, if bit 7= 1, it means low voltage.
The actual voltage is 0010 0000 = 0x20 = 32, 32*0.1v =3.2v
2. Version Packet:
When Report Type=0x00 is the version packet, such as 013E000A0B202005200000, the firmware version is 2020.05.20

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 variation 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. Installation
1. R718F2 has a built-in magnet (as the figure below). When
installed, it can be attached to the surface of an object with
iron which is convenient and quick.
To make the installation more secure, use screws (purchased
separately) to secure the unit to a wall or other surface (as the
figure below).
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.
2. Tear off the 3M glue at the bottom of the reed switch probe
and the magnet (as the red frame in the figure above). Then,
stick the reed switch probe to the door and is parallel to the
magnet (as the figure on the right).
Note:
The installation distance be
tween the reed switch probe and
the magnet should be less than 2cm.

When installing the device, the magnet must move along the X axis relative to the sensor.
If the magnet moves along the Y axis relative to the sensor, it will cause repeated reports due to the magnetic field.
R718F2 is suitable below scenarios:
Door, window
Machine room door
Archives
Closet
Refrigerators and freezers
Cargo ship hatch
Garage door
Public toilet door
The place needs to detect the opening and closing status.
3. When the door or window is opened, the reed switch probe is
separated from the magnet, and the device sends an alarm
message about the opening.
When the door or window is closed, the reed switch probe and
the magnet get closer, and the device restores to the normal
state and sends a state message about the closing.

Note:
Please do not disassemble the device unless it is required to replace the batteries.
Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries. Please use suitable
screwdriver to tighten the screws (if using an electric screwdriver, it is recommended to set the torque as 4kgf) to ensure the
device is impermeable.
7. Information about Battery Passivation
Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many
advantages including low self-discharge rate and high energy density.
However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium
anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high. This lithium chloride
layer prevents rapid self-discharge caused by continuous reaction between lithium and thionyl chloride, but battery passivation
may also lead to voltage delay when the batteries are put into operation, and our devices may not work correctly in this situation.
As a result, please make sure to source batteries from reliable vendors, and it is suggested that if the storage period is more
than one month from the date of battery production, all the batteries should be activated.
If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.
ER14505 Battery Passivation:
7.1 To determine whether a battery requires activation
Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit.
If the voltage is below 3.3V, it means the battery requires activation.
7.2 How to activate the battery
a. Connect a battery to a resistor in parallel
b. Keep the connection for 5~8 minutes
c. The voltage of the circuit should be ≧3.3, indicating successful activation.
Brand Load Resistance Activation Time Activation Current
NHTONE 165 Ω 5 minutes 20mA
RAMWAY 67 Ω 8 minutes 50mA
EVE 67 Ω 8 minutes 50mA
SAFT 67 Ω 8 minutes 50mA
Note:
If you buy batteries from other than the above four manufacturers, then the battery activation time, activation current, and
required load resistance shall be mainly subject to the announcement of each manufacturer.

8. Important Maintenance Instruction
The device is a product with 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 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.
9. Description of Waterproof Grade
1: According to Enclosure Protection Class
This standard is equivalent to IEC 60529:2001 Degrees of Protection Provided by Enclosures (IP Code) (English version)
2: The test method of IP65 waterproof grade is: spray the device in all directions under 12.5L/min water flow for 3min, and the
internal electronic function is normal.
The test method of IP67 waterproof grade is: the device is immersed in 1m deep water for 30min, and the internal electronic
function is normal.
IP65, dust-proof and to prevent damage caused by water from nozzles in all directions from invading electrical appliances. It can
be used in general indoor environment and sheltered outdoor environment. It is not suitable for use in environments with high
water pressure, high temperature and high humidity, such as long time direct sunlight outdoors and possible direct exposure to
rainstorm. If it is really necessary to install in harsh environments, it is recommended to add sunscreen and rainproof shields when
installing.
Case I (face down with LED and buttons) Case II (installed under the rain shield)
