WDC Workplace Data Collector – User Manual 9

2 Introduction

The Inotec Workplace Data Collector (WDC) for occupancy is designed to detect the
occupancy of a desk or workplace position within an office environment.
Occupancy data is transmitted wirelessly to an Inotec wireless Access Point (AP)
and from there to a central database where it can be used to make informed
decisions regarding the workplace utilisation and efficiency.

The WDC can be located up to 80m away from an Access Point. With objects in the
way a more typical range is 50m.

The battery powered WDC is designed for long life. The WDC batteries will
typically last over 3 years. However, to ensure continuous operation new batteries
should be fitted every 36 months as part of a routine maintenance schedule.

This manual details the WDC installation and service procedure.

Battery Holder

1) Open the WDC case and ensure that 3 x good quality AAA batteries are fitted in
the correct orientation as shown in the diagram printed on the back wall of the
battery holder.

The WDC is supplied from the factory without batteries fitted.
Only good quality batteries should be used.

2) Upon fitting the batteries the red and green indicator LEDs will flash for 10
seconds, indicating the unit is functioning correctly. If the LEDs do not light up
then check the batteries are fitted correctly.

3) Replace the lid onto the base plate ensuring the catches on both sides of the unit
click into place. Make sure the antenna wire is kept safely inside the case and
does not get caught or damaged between the lid and base.

4) Insert the anti-tamper screw and tighten using a crosshead screw driver as shown
in Figure 1.0

WDC Workplace Data Collector – User Manual 15

6 Software Information

1) Once the batteries have been installed, the WDC-Occupancy sensor will go
through a software start up procedure, Using the inotec WEMS PC software
package and to ensure correct operation the following should happen in
order;

Start-up

Ready

WDC Workplace Data Collector – User Manual 16

Unoccupied

Occupied

Watchdog, Unoccupied

WDC Workplace Data Collector – User Manual 17

Watchdog, Occupied

2) The key chart for the software graphic symbols for start up, is as follows;

 Power onWDC, or handover sensor = ‘S’ = Start-up

 Walk or move away from sensor to enable the WDC to measure the back ground temperature.

 15 seconds later = ‘R’ sensor is ready for operation

 Then it’s ‘U’ for Unoccupied;

 Or ‘O’ for Occupied.

 ‘H’ for Hot Seat Compensation ~ 3 Mins

 ‘W’ for Watchdog, ~ 10mins.

 ‘A’ for Ambient temperature change, approx 1C (10 Units)

3) WDC will only transmit on change of state (occupied/unoccupied), but will send
data every 10 minutes (Watchdog), to confirm operational.

 WDC transmits when ambient value changes by 1 degree

 WDC will automatically determine the unoccupied IR sensor value and calculate

occupied status as a temperature approximately 3 degrees above unoccupied level.

 The WDC utilises the PIR sensor to detect movement as an indication of activity.

 WDC uses the PIR sensor to indicate unoccupied state, when person has left.

WDC Workplace Data Collector – User Manual 18

 WDC transmits battery voltage level

 WDC transmits the software version and the WDC type

 The WDC transmits but does not receive. Receiving is possible but would

drastically reduce battery life.

4) The WDC can be updated by opening the external case and connecting to the
programming interface provided. No “over the air” update is included at this stage

5) A ‘reset/test’ function is provided by a person holding their hand directly over the
WDC sensors for 5seconds. This will allow the WDC to re-establish, re-learn, the
background temperature. It is intended for use during WDC installation or on
relocation of the sensor. This function will also be automatically enabled if the
sensor detects no significant temperature changes over 3 minutes. The intent is to
allow the sensor to automatically adjust to changing ambient changes over time

6) WDC Occupancy software process

 The WDC resets its Auto Level at the end of every 15s of low Ir activity AND the

WDC is Unoccupied.

 A high negative change on the PIR value will set the WDC as Unoccupied.

 The WDC resets its Auto Level at the end of 3mins of low Ir and PIR activity, with

the WDC in Occupied state.

 In hot seat, the status can be sent from the WDC to allow the SQL to deduct 3

mins from the "unsure" WDC occupancy. (“Warm Seat” situation). Not required by
JCI at this point.

 The "Hand on Sensor" reset should be maintained and improved.

 Ambient will be converted to Degrees C inside the WDC. This indicates the

individual workplace working desk environment temperature situation.

 Pir activity can be used to indicate the active use of the workplace seat.

 Battery voltage is always transmitted

 Heartbeat transmission should be 10mins.

 3 modes of data transfer should be considered: -

WDC Workplace Data Collector – User Manual 19

 Transmit every 1 second for detailed debug.

 Transmit on change of Ir for lower level Debug.

 Transmit on change of Occupancy, two packets of information are sent to ensure

one gets to the receiver.

7) Sensor type and software version will be held and transmitted for remote
verification.

8) PIR value is the range of the PIR between transmissions.

7 Hardware Details

1) Hardware WDC Occupancy details

The WEMS workplace data collector (WDC) is utilised to provide occupancy data
from desk workplace positions within an office environment, The WDC will be
utilised in a normal office environment, with temperatures ranging from 18 to 25
degrees C, with normal humidity and should not be pointed into direct sunlight or
heat sources.

2) The Workplace data Collector WDC will provide a battery-powered unit, including a
wireless link, for each workplace desk area for detection of occupancy or no
occupancy of change in IR and PIR levels.

3) Typical wireless range of a WDC is 80 metres line of sight; with obstructions, the
effective range is reduced to approximately 50 metres for normal office
applications.

4) WDC will be battery powered, with an approximate life of >24months (subject to
utilisation transmissions), we recommend changing batteries as a planned
maintenance action every 36 months. In addition, the battery level will be
transmitted and can be included as part of facility maintenance.

5) The WDC will run off 3xAAA batteries, a good quality battery must be utilised.

6) Data will be transmitted at different frequencies depending on country or regional
requirements; We have provided the following ISM bands for global regions. This
data can change over time. Access point frequencies are: -

 Japan - 315Mhz

 434 MHz Asia pacific regions, including China, Philippines, Australia. (Global)

 868Mhz UK & Europe

 915Mhz North & South America

WDC Workplace Data Collector – User Manual 21

7) WDC will be dedicated to the ISM frequency band required for that region and
country. Taking into account local power settings and duty cycles.

8) WDC will be tested accredited and validated for the region it will operate in, as
shown below proposed accreditation, self certification will take place after testing
products; Others will be added as more local country standards are adopted.

 ETSI EN 300 220, - UK and Europe

 FCC CFR47 Part 15, FCC - US

 ARIB RCR STD-T30, ARIB STD-T67 and ARIB STD-T96 – Japan

9) WDC will transmit on low power RF to maximise the battery life. (Tweet and Sleep)

10)There are no tamper proof devices within the WDC, it is assumed the data can be
translated and sampled by JCI, to confirm if WDC is being tampered with.

11)The WDC will only transmit on change of state (occupied/unoccupied), but will
send data once, every 10 minutes, to confirm operational.

12)To stop data transmit event clashes with numerous WDC’s transmitting
simultaneously, the WDC will be programmed in to “listen before talk” mode to
eliminate collisions.

13)Inotec will provide product traceability for all our products, in the following way; IP
Address, QR Bar Code, Base Freq, Software Level, Product Symbol, Eng Level,
Country via a label on the product. (TBE)

14)The WDC should be positioned under the desk centrally, approximately 500mm
from the front of the desk or table; this will provide a reading range of 300mm
from the front of the desk or table, 60 degrees angle.

WDC Workplace Data Collector – User Manual 22

15)The WDC unit is now ready to be fitted under the desk to be monitored. The WDC

can be fixed under the desk using double-sided adhesive pads, or by using the
screw holes provided in the base as shown below

The WDC must be installed under the desk, 500-300mm back from the front edge
– directly opposite the place where the worker is likely to sit. The WDC will then
detect up to 800mm from the installed position, providing 300mm sensing range
from the desk as shown below:

range

When positioning the WDC, ensure that the sensors have a clear line-of-sight to
the position where the user sits, with no obstructions in the way.

Ensure that the WDC is mounted flat against the underside of the desk. Note that
the WDC has been designed so the sensors point slightly downward by default.
This ensures the sensors are pointing down at the workstation occupant, and not
upwards towards the underside of the desk.

WDC Workplace Data Collector – User Manual 24

Ensure that you leave enough space at the back of the unit to allow a finger to be
inserted to depress the lid release catches so the lid can be removed for servicing
or battery replacement.

Fig. 7 WDC Lid Release Access

For correct operation the WDC requires a normal office environment, with
temperatures around 18 to 25 degrees centigrade and normal humidity. Therefore
the WDC should not be placed in direct sunlight or near heat sources such as fan­heaters or radiators.

16)After securing the WDC in place the unit must be reset by holding your hand
directly over the WDC sensors for 5 seconds. This forces the WDC to re-establish
its background temperature. This reset operation should be performed whenever
the WDC is moved or opened for servicing.
