4.3. Motion Sensitivity

By Former user (Deleted)

This feature helps users define how sensitive a Response SN3 can be to motion. Motion can be defined as PIR detecting a change in heat generated by a person moving in its surroundings.

The default configuration for Motion Sensitivity in Response SN3 is,

  • High in FW < 191.27.

  • 52% in FW ≥ 191.27.

4.3.1 Why and When to Change Motion Sensitivity?

Motion sensitivity may require adjustments to its sensitivity depending on how the space will be used and the conditions under which it will be installed. Primary reasons may include,

  1. A limited number of sensors in a room doesn’t provide enough coverage.

  2. Users report that they have to move every now and then to turn the lights on.

  3. Lights turn on when there is no movement in its surroundings.

Use Case 1: A small meeting room has only one sensor node installed due to limited space. The users in that space feel that they have to move every now and then for the sensor to pick up motion. In such scenarios, it’s recommended to increase the motion sensitivity to higher value.

Use case 2: Let’s say a Response SN3 is located near an HVAC outlet due to space restrictions. During HVAC operating hours there is a sudden change in temperature that can cause the Response SN3 to false trigger in absence of occupancy. This can be solved by changing the motion sensitivity of the said node to lower value and enabling the idle threshold.

4.3.1.1. Idle Threshold

When a node stops seeing occupancy in an on/auto operation mode it goes to standby mode. Idle threshold is a higher threshold value that is activated with the standby mode. An increase in threshold can make the sensor less sensitive to motion and vice versa.

The Idle Motion Mode helps users control whether the threshold is increased or kept at default in the standby mode.

The operational principles of Idle Motion Mode and configuration is explained below,

4.3.1.1.1. Disable Idle Motion Mode image-20240726-025403.png

Nodes don’t increase the idle threshold and thus become more sensitive as compared when its enabled.

Suitable where users enter a space and experience poor detection.

4.3.1.1.2. Enable Idle Motion Mode image-20240726-025109.png

Nodes will increase their Idle Threshold when in the standby mode and become less reactive to motion.

Enable Idle Motion Mode If you are experiencing issues with false triggering when the luminaires are in an Idle state.

The nodes with firmware version 191 or higher have the option to disable/enable the Idle motion mode whereas all previous firmware have this always enabled.

By default, the Idle Motion Mode is disabled.

4.3.1.2 Configure Motion Sensitivity Using Response App

Motion sensitivity configuration for your installed sensor nodes can differ based upon the firmware (FW).

4.3.1.2.1 Response Nodes with FW < 191.27

Log in to the app and select your Response SN3. Click on the configuration menu and go to Motion Sensitivity

  1. Press relay if you wish to relay the settings

  2. Use slider - slide right to increase the sensitivity and vice versa. The furthest right setting is ‘High,' and the furthest left setting is 'Disable’.

Disable, Low, Medium & High

  1. Press Query to read the current PIR sensitivity

  2. Press Save to Save settings.

4.3.1.2.2 Response Nodes with FW ≥ 191.27

Log in to the app and select your Response SN3. Click on the configuration menu and go to Motion Sensitivity

Go to Motion Sensitivity

  1. Press relay if you wish to relay the settings

  2. Use slider - slide right to increase the sensitivity and vice versa.

Increasing the motion sensitivity above 60% will display a warning. This warning is intended to prevent you from increasing the motion sensitivity to a higher level that could lead to an increased risk of false detections.

Refer to Glossary of Terms for all motion sensitivity percentages available via the Response App.

  1. Press Query to verify the current PIR sensitivity

  2. Toggle this right to enable Idle Motion Mode and toggle left to disable Idle Motion Mode.

  3. Press Save to Save settings.

If you click on the information tab image-20240816-081111.png in the image, you can see the details pop up in a small window as shown in the right image.

4.3.1.3 Configure Motion Sensitivity using Response IR App

Login to the app and point your charged and working dongle towards your Response Node

Go to Other parameters

  1. Select High, Medium, Low or Disable

  2. Press relay if you want to relay settings

Please change the motion sensitivity only where it is necessary and be mindful when you change the motion sensitivity to “Low” or “Disable” to prevent any possible safety hazards.

If a Response SN3 is installed near a mechanical or electrical device (e.g. an air conditioning supply outlet, a strong Wi-fi router), this may trigger a false activation of the Response SN3’s motion sensor. This means that the luminaire may think an occupant is nearby and switch on due to change in temperature and other interruptions, unnecessarily increasing energy consumption.

Please refer to 4.3. Avoiding Interference to read more on how to avoid electrical interference.
