1.10. Response Radio Devices
1.9.1. Introduction
The Response Radio Devices are a new family of products that the Organic Response team has built from the ground up. They are a new type of control node designed to extend the reach and coverage of an Organic Response mesh. These devices don’t detect presence themselves but instead listen to nearby Response Sensor Nodes for instructions and will dim up/down to match those neighbors.
They come in two variations:
Response Radio - A small device designed to be integrated inside of a luminaire.
Supports control of up to 12 DALI devices.
1.9.2. The Product
Product Version: 2.0
Firmware Version: 2
The Response Radio devices uses RF to communicate with the neighbouring Response SN3, allowing them to be installed hidden in the ceiling and out of sight. With no infrared connection, the Response Radio device does not have any sensing or decision-making capabilities of its own. Therefore in Response Radio devices, we only have RF component and that can only take information from a neighboring Response Sensor Node. It doesn’t house any capabilities such as PIR motion sensing, IR communication, ambient sensing or associated control operations. The intended use of passive node could satisfy the following needs in your projects,
Maintain Connectivity: To keep the network contiguous through areas where a room divider, a stairwell or a gap in luminaire layout has created a ‘dead zone’.
Avoid Special Installation Constraints: As Response Radio device can be installed out of sight that may suit in scenarios where changes to ceiling aesthetics are restricted. Or in examples where smaller footprint luminaires or Emergency exit signs are used amidst of regular OR integrated luminaires thus reducing the labour and complexity.
Response Radio device linked to a Response SN3 for EM testing ( Response portal-connected projects)Cost Savings: A Response Radio device is a more cost-effective control option than a Response SN3, or a Detached Response SN3.
Please note that Response Radio devices should NOT be used as an alternative to a traditional Response Sensor Node when presence detection is required.
Response Radio devices should ideally be placed within 10 meters non-LOS with at least one or more Response SN3 to allow network continuity. Please note this distance is not necessarily required between a publisher and subscriber there could be several nodes between them that can act as a bridge for communication. However network continuity can be adversely affected by several installation factors and interference introduced by the environment. Always test your installation during configuration for continuity of communication.
1.9.3. Operational Principle
Instead of usual peer-to-peer communication between Response Sensor Nodes, the Response Radio devices forms a subscriber relationship to a configurable publishing Response Sensor Node. As a result, the Response Radio device will follow the same commands as issued by the publishing Response Sensor Node and in turn implement those control measures for devices directly connected to itself over DALI. In a typical scenario what this will look like is imagine a corridor,
In the above application example key operations will takes place as below,
The Response Radio device will be configured to subscribe to a Response SN3 using a unique channel where the Response SN3 on the left will be a publisher to that same channel, as shown by blue dotted line - (later referred to as pub-sub channel).
At the same time, the 2nd Response SN3 on either end of corridor will also be linked wirelessly to capture occupancy entering from the either end of the corridor. They can be linked using new wireless linking method also known as Channel Link. (Click here to read more on channel link)
Now if there is an occupancy under any Response Sensor Node the communication will be shared through Wirepas over new group link between both Response Sensor Nodes.
The Response Radio devices being a subscriber to at most one Response SN3 will receive the same dimming command as that Response Sensor Node would have issued over DALI i.e. causing the luminaires connected to Response Radio devices dim to same light output as luminaires connected to publisher Response Sensor Node in response to their occupancy. This means the light output will follow the maxlight & personality configuration of the publishing Response Sensor Node.
Use Case : Let’s say Response Sensor Node A is configured as a publisher with group ID 122 and Response Radio A is configured as subscribers for group 122 as illustrated in the figure above. When the node A detects a motion it will give a configured max light output e.g., 100%. At the same time Response Sensor Node A publishes a control command. The subscriber Response Radio configured for group ID 122 will receive this control command and turn on the lights with light output level 100% for devices directly connected to itself over DALI.
However, due to personality the nearby Response sensor node B received an occupancy message from Node A and decided that it should take 80 % light output. Since Response Radio B is configured to the same group as Response sensor node B it will also output 80% light output as it received the same control command from it publisher for group 14.
1.9.4. What to Expect (Out of Box)
Response Radio devices without having any of the control elements that we find in Response sensor node will have its own unique behaviour. They come unassociated to any Response sensor node and independent of any control publishers therefore they must be first configured to a neighbouring Response sensor node before they can exercise any control operations. Similar to Response SN3 they do however, have built-in integration test which works in a similar fashion to that of a Response SN3. Please refer to (Integration Test) for details on the integration test and sequence of actions that are followed. At the end of the test the Response Radio device will implement the last control as the default operation mode such as,
If tunable white the colour temperature of the connected luminare will be set to operate at 4000K
The light output of the connected luminaires will be at a dim percentage of 100%
