Introduction

R313WA is a Class A 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.

Insert two sections of 3V CR2450 button batteries and close the battery cover.

---|---
Turn on| Press any function key till green and red indicator flashes once.
Turn off (Restore to factory setting)| Press and hold both function keys for 5 seconds till green indicator flashes for 20 times.
Power off| Remove Batteries.

Note:

| 1.Remove and insert the battery; the device memorizes previous on/off state by default. 2.On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor

inductance and other energy storage components.

3.Press any function key and insert batteries at the same time; it will enter engineer testing mode.

Low Voltage Warning

Data Report

When the device is turned on, it will immediately send a version package. The transmission frequency of sending version package is once every 24 hours. 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)
Detectiontime:0x001E (30s)

The setting of 2-gang is same.
DisableTime must ≧5s , Detection Time must ≧ DisableTime .

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:
The reported data is decoded by the Netvox LoRaWAN Application Command document and Data report configuration and sending period are as following:

Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V

Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BatteryVoltageChange value.

Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.

Example#3 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.

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.

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:
a. A DetectionTime is finished
b. 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.)

Disable time and Detection time
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.

Example1:
While DetectionTime is 60 secs and DisableTime is 30 secs, no pressure is detected after triggered.
R313WA will report un-pressure after 60 secs (DetectionTime).

Example2:
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

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：
   

2. Wipe the surface clean before installation to avoid dust on the surface to affect the adhesion of the device.

3. 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.

4. Tear off the 3M adhesive on the back of the sensor and stick the sensor to the seat.

5. one of the 2-gang seat occupancy sensor detects external pressure (not less than 200g).It will also report to the gateway.

6. 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

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 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. 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.
