What is the WK-PIR?

The WK-PIR is a presence sensor for use with the Rako wired system. It is supplied with a WK-CONNECT for a CAT5/CAT6 punch-down connection.
Features include:

• Three modes
  • Always (not time based)
  • Time range mode
  • Sunlight mode
• Webpage programmable
• Absence detection
• Ease of installation via the WK-CONNECT

The introduction of programming through the WK-HUB via the webpages using ‘Hub managed mode’, enables time-dependent automatic Scene selection, allowing for different scenes at different times of the day.
NB
A WK-HUB is required to program and operate the sensor.

Installation Instructions

 ●  Using an appropriate hole saw, make a  48mm cutout in the ceiling.|
---|---
 ●  Connect the sensor to the Rako wired  network through the RJ11 cable onboard the WK-PIR via the  WK-CONNECT  (included with the  WK-PIR).|
 ●  Using a punchdown tool, connect the CAT5 cores to the inputs on the  WK- CONNECT.|
 ●  Terminate the WK-CONNECT  according to its position in the wired  network.
See ‘Terminating the WK-CONNECT’ for more  information on page 4.|
 ●  Replace the WK-CONNECT cover and  ensure the cables are secured.|
 ●  Raise the fixings on the WK-PIR and  insert into the ceiling cutout.
●  Ensure there is adequate clearance and  nothing is obstructing the springs|

Terminating the WK-CONNECT

It is important to terminate the WK-CONNECT correctly; otherwise, the wired system will not function. The required termination depends on the nature of the installation and the position of the WK-CONNECT within the system. Examples of wiring within a system can be found in Appendix 2.
No Term: Both Jumpers removed
Used when the WK-PIR is not at the end of line. This is usually identifiable by two cables being punched down to the WK-CONNECT. Term: Jumper fitted across 1+2 and 4+5
Used when the WK-PIR is “end of line” in a radial configuration. Star Term: Jumper fitted across 2+3 and 5+6
Used when the WK-PIR is “end of line” in a STAR wire configuration.

Commissioning the WK-PIR Sensors

The following steps assume:

1. A Rasoft Pro project file has been created and rooms have been added
2. The HUB is set up as a communication device
3. The HUB is added as a device to Rasoft Pro
4. The “Smartphone/web data” tab has been used to upload the

Room/Channel/Scene data to the HUB
For information on creating a Rasoft Pro project file and adding the HUB as a device, refer to the links below.

• Wired system setup guide
• WK-HUB instruction manual

To commission the WK-PIR via the HUB webpages:
– Access the HUB webpages by right-clicking the HUB in “Communication Devices” and selecting “Open in browser”
– Select “Configuration,” “Modules,” and “PIR” ![Crako WK PIR Wired PIR Sensor

• commission](https://manuals.plus/wp-content/uploads/2024/03/Crako-WK-PIR- Wired-PIR-Sensor-commission.jpg) – Select “Go To Sensors” – Select “Commission Sensor” – Once the Sensor commissioning has finished, the HUB will have assigned unique ID’s to the WK-PIR’s, in the example shown the ID is 1124. – Enter a Description. – Select ‘Create’, the WK-PIR has now been added as a sensor
  If there is more than one WK-PIR, repeat the previous steps before moving on to the next section.

Adding a Controller

The Controller defines when the WK-PIR turns on lights and when it doesn’t; this can be conditional to the time of day, keypad inputs, or the status of other sensors.
– To get to the Controller, press “Back” on the sensor commissioning page
– Select ‘Configure Controllers’ – Select “Add” at the top right to create a new Controller
– Select the Room and Channel the sensor will control
– Give the Controller a description
– Select the sensor which will be managed by the Controller. Additional sensors can be added to the Controller later
– Select a template, the following options are available:
Standard
The sensor is operational all day and night, on movement, the Controller will switch to scene 1, and on timeout, the ‘Off Command’ in Controller will activate.
Day/Night
The sensor recalls different Scenes depending on the time of the day; between Dawn and Dusk Scene 1 is the ‘On Command’ and between Dusk and Dawn Scene 4 is the ‘On Command’. In both cases, the ‘Off Command’ will activate on timeout in the Controller. Dawn and Dusk times change throughout the year automatically. In the example above, the Day/Night template is selected

Programming a Controller

Once the sensor has been added to the Controller, it will operate according to the setup without further programming. Should there be additional programming requirements, such as adding additional sensors to the controller or changing the Time Range Configuration, select ‘Manage PIR Controller’.

1. Controller Description
   Give the Controller an accurate description to make the programming clear and easy to understand.

2. Room
   The Room of the Controller, the sensors in the section below will affect the Room selected.

3. Channel
   The Channel within the Room, with “Whole Room” set, the Controller will switch the whole Room; with a single channel set, the Controller will switch a single channel.

4. Sensors
   Lists the sensors within the Controller, and the corresponding time stamp of their last activity.

5. Add sensors
   Commissioned sensors will appear in the list when “Add sensors” is selected.

6. Time Range Configuration Overview
   Adjusts the parameters of the Controllers “On Command” and ‘Off Command’.

Time Range Configuration

The time range configuration determines when the PIR will activate on movement and when it will time out.

1. Always
   The sensor will always activate the ‘On Command’ on movement detection.

2. Time Range
   The sensor will activate between specific times as set by the 24-hour clock.

3. Sunlight Mode
   The sensor will activate based on the Dawn/Dusk or Sunrise/Sunset conditions.

4. Exit Delay
   When ‘Off’ is pressed for the room, the sensor will not activate the lights on movement for 30 seconds. This option prevents unintentional activation if movement is detected while switching the lights off via the switch.

5. Absence Mode
   Ensure ‘On Command’ is disabled in Absence Mode
   Triggers the ‘Off command’ after a specified period if no movement has been detected.
   This is commonly used to prevent lights from being left on unintentionally.

6. Timeout
   When movement is detected, the countdown begins. Upon further movement detection, the countdown timer resets. Once the timer countdown is finished, the ‘Off Command’ is activated. The countdown timer can be set by hours, minutes and seconds.

7. Set On Command
   When the sensor has detected movement, the ‘On Command’ will be activated by the Controller, provided that the conditions are met, such as ‘After Dusk’ or ‘After 13:00’.

8. Set Off Command
   When the Controller has timed out, the ‘Off Command’ will be activated. The ‘Off Command’ can be any Scene including ‘Off’.

Appendix 1: Sensor Commands and Controller State

Sensor Commands
The sensor sends three commands:
Start Motion
When movement is first detected the sensor will send a Start Motion command to the Controller. The Controller logic will then determine whether or not to send the ‘On Command based on the time conditions and keypad override state. If the ‘On Command’ is triggered the timeout will begin. Once the timeout reaches its end the ‘Off Command’ will be triggered.
Continue Motion
Once the sensor has sent ‘Start Motion,”when motion is detected, a ‘Continue Motion’ is transmitted. This will restart the Controller timeout but not re- send the ‘On Command’.
End Motion
When movement is no longer being detected by the sensor, an ‘End Motion’ command will be triggered by the sensor to the Controller.
Live Status
Live status shows the current state of the Controller. Trigger Motion
Forces the Controller to send the ‘On command’ as if movement has been detected on a sensor.
Trigger Timeout
Forces the Controller to begin the timeout; once the timeout has been reached, the Controller will send the ‘Off Command’.
Disable Controller
Disables the Controller indefinitely; this will not remove the Controller, to delete the Controller, select ‘Delete’ at the bottom of the Controller menu.
Enabled
If the Controller has been disabled, this will show as ‘Disabled’; the default setting is ‘Enabled’.
Last Event
The last time a sensor detected movement, and updated the Controller.
State
The current state of the Controller, there are four states:
On Override
When a Scene or Level of 1% or higher is sent from the Room of the Controller which is not from a sensor , the Controller will enter an override state. When an ‘Off’ or Level 0% is sent from the Room, the Controller will no longer be On Override.
On
Movement has been detected by the sensor, and the Controller ‘On Command’ has been triggered.
Timeout
The sensor is no longer detecting movement; the Controller Timeout has started.
Off
Once the Controller Timeout reaches the end and no movement has been detected during the timeout period, the ‘Off Command’ will be triggered.

Appendix 3 Sensor Performance Data:

Technical Specifications: Detection area (2.5m): We highly recommend that testing at the intended location be conducted before installation to ensure that the expected results are achieved.
If the application requires sensitive operation with a coverage of (8m+) we highly recommend that multiple WK-PIR sensors are installed as required.

Appendix 4: Installation Considerations:

Sensors only provide binary on/off information back to the Rako system. This means they do not provide information about the location or nature of the object in view. Consideration of the environmental factors which could trigger the sensor is of paramount importance in successfully implementing a sensor to the customer’s requirements.
The function of sensors gives rise to certain limitations about their operation:

• Sensors cannot detect stationary objects.
• Sensors are sensitive to environmental conditions which can cause false triggering and other undesirable effects:
  • Avoid locating the WK-PIR in areas intermittently affected by direct sunlight.
  • DO NOT locate a sensor in an area with forced air ventilation, either in the room or ceiling void above the location of the WK-PIR.
• Sensing areas are non-uniformly distributed, causing areas of higher and lower sensitivity, requiring larger motions to trigger the sensor in some areas than others.
• Sensors are more sensitive to tangential motion than radial motion at the periphery of the sensing area.

The sensitivity at the extremities of the field of view shown above will have reduced sensitivity compared to the centre.
Expect reduced performance at the extremities of the field of view of the sensor.
PIR sensors only provide binary on/off information back to the Rako system. In context, this means they do not provide information about the location of the object in view or what the object is, which means consideration of the environmental factors which could trigger the sensor are of paramount importance in successfully implementing a PIR sensor to the customer’s requirements.
