1. Introduction
R313WA is a ClassA wireless 2-gang seat occupancy device based on standard LoRaWAN protocol. The R313WA will report
to the gateway whenever one of the 2-gang seat occupancy sensor detects external pressure. It will also report to the gateway
when the external pressure is gone.
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
Insert two sections of 3V CR2450 button batteries and close the battery cover.
Note: users may need a flat blade screwdriver to open the battery cover.
Turn on
Press any function key until the green and red indicator flashes once.
Turn off
(Reset to factory setting)
Press and hold both function keys for 5 seconds until the green indicator flashes for 20 times.
Power off
Remove Batteries.
Note:
1. The device would memorize the previous on/off state by default even when user removes
and inserts the battery.
2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor
inductance and other energy storage components.
3. The device will be in engineer testing mode when user presses any function key and inserts
batteries at the same time.

2. The transmission frequency of sending version package is once every 24 hours.
3. Data will be reported once per hour by default setting.
Default setting:
Maximum time: 3600s
Minimum time: 3600s
Battery: 0x01 (0.1V)
Disabletime:0x001E (30s)

4. Pressure detecting:
R313WA is equipped with two-gang seat occupancy sensor.
When the seat occupancy sensor detects changes with the pressure status R313WA will report.
When the seat is taken, report 1.
When the seat is not taken, report 0.
Note:

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 change value 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. Seat Occupancy Delay Configuration
There is a delay configuration specially designed for battery saving. The delay configuration logic includes DetectionTime and
DisableTime.
DisableTime is the sampling period;
DetectionTime is the detecting period. (Please find further info regarding DisableTime and DetectionTime below.)
(1) When R313WA detects pressure caused by the occupancy of the seat, it will report 1 (indicating the seat is taken) and
other status (battery for example).
(2) The delay configuration will be triggered after the occupancy is detected.
Once the delay configuration is triggered, the device will enter the detecting and sampling period
(i.e. the DetectionTime and DisableTime.)
Note: How long you set the DetectionTime and DisableTime will determine the number of the periods of DisableTime
R313WA will only report 0 (indicating the seat is unoccupied ) when the following is both fulfilled:
(1) A DetectionTime is finished
(2) No pressure is detected during the DisableTime (the default setting is 30 seconds, and it can be changed)
Note: If DetectionTime and DisableTime are not set to the same, there will be multiple DisableTime periods, and all of them
should detect no pressure to fulfill this prerequisite.)

11
Disabletime and Detectiontime
Once the device enters the DisableTime, it will stop detecting for the first 70% period of the DisableTime, and it will be back
to detection for the remaining 30% of the DisableTime. If pressure/occupancy is detected during the remaining 30% of the
DisableTime, R313WA will enter the next period of DisableTime.
Example 1:
While DetectionTime is 60 secs and DisableTime is 30 secs, nopressure is detected after triggered.
R313WA will report un-pressure after 60 secs (DetectTime).
Example 2:
While DetectionTime is 60 secs and DisableTime is 30 secs, pressure is detected during 25th sec.
R313WA will restart pressure detect procedure (DetectionTime).
No pressure is detected during next DetectionTime and R313WA therefore report un-pressure

7. Installation
1.Remove the 3M adhesive on the back of the Wireless Seat
Occupy Sensor and attach the body to the surface of a
smooth object (please do not stick it to a rough surface to
prevent the device from falling off after a long time use)
Note：
1. Wipe the surface clean before installation to avoid
dust on
the surface to affect the adhesion of the device.
2. Do not install the device in a metal shielded box or
other electrical equipment around it to avoid affecting
the wireless transmission of the device.
2. Tear off the 3M adhesive on the back of the sensor and
stick the sensor to the seat.
3. one of the 2-gang seat occupancy sensor detects external
pressure (not less than 200g).It will also report to the
gateway.
4. When no pressure is detected during DisableTime
(occupancy delay configuration,default:30s, can
modify) ,R313WA will report un-pressure
Note:
When the seat is taken, report 1.
When the seat is not taken, report 0.
Wireless Seat Occupy Sensor is suitable for the following
scenarios:
⚫Theater seat detection
⚫Conference hall seat detection
⚫Large classroom seating detection
⚫Performance of the stadium seating status

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 a dusty or dirty environment. It might damage its detachable parts and electronic
components.
⚫Do not store the device under excessively hot conditions. High temperatures 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 the device 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 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.
