1. Introduction
R718PQA is a long-range wireless occupancy and door sensor for Netvox Class A type devices based on LoRaWAN open
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.

Occupancy alarm:
If there are movements of people, animals or any organism in the detected area, the infrared sensor detects the infrared
signal. And, if the closing event happen in the following 10seconds, the device will report Occupy status.
Occupy status = 1
Unoccupy. status = 0
Note:
The data transmission period of the device is subject to the programming configuration before shipment.

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. IR Disable Time and Detection Time
If there are movements of people, animals or any organism in the detected area, the infrared sensor detects the infrared signal.
And, if the closing event happen in the following 10seconds, the device will report occupy status=1.
After IRDetectionTime(Default 30s), if there is to no longer people, animals or any organism movement detected by the R718PQA
within the monitoring range and the reed switch status is detected as open, the device will report occupy status=0.
To save the power, when R718PQA detects the infrared signal, it will enter IRDetectionTime period. If there is no infrared signal
detected in IRDetectionTime period. It will report un-occupy.
IRDisableTime is the sampling period during IRDetectionTime (IRDisableTime are 30 seconds by default setting that PIR is off
for first 70% of the period; on for rest 30% of the period).
For example, after triggered, the PIR will turn off the infrared probe for 21 (30 * 70%) seconds to save the power, living objects
within this period will not be detected. PIR will re-open detection function after 21 seconds, if it detects living objects in this
period, the IR delay time will be extended for another 30 seconds till no infrared signal is detected and IRDetectionTime period is
due and R718PQA will then report un-occupy
Note：IRDisableTime >=5 s, IRDetectionTime>= IRDisableTime
Default disabletime：30s detectiontime：5min
Example1:
The IRDetectionTime is 60 seconds and the IRDisableTime is 30 seconds, no living creature is detected during the two 9-second
detection period (the yellow parts shown below). R718PQA will report “unoccupied” after 60 seconds (IRDetectTime).
Example2:
The IRDetectionTime is 60 seconds and IRDisableTime is 30 seconds, living creature is detected at the 25th second of the first 30
seconds. R718PQA will restart the IR detecting procedure (IRDetectionTime).
No living creature is detected during the next IRDetectionTime and R718PQA therefore report “unoccupied.”
Note: Occupancy status (status =1) requires both reed switch and infrared to detect close/someone and interval between both less than 10 seconds.

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.

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