Organic Response (OR) Integrated Sensor Technology is the cutting edge offering in the layer of Intelligent-Automatic controls.

OR affords greater levels of customisation from simple standalone occupancy based control through to the IoT cloud hosted portal.

Tiers of Simplicity 


8 - tiers


The Intelligent OR integrated Solution:


a.       Decide on your application and the way the environment is to be controlled.  

b.      Sensors are inside the luminaire – Installation occurs once for light and control in one instance. 

c.       There is no cabling (expect the lighting circuit) or network designs to consider

d.      Lights and control will work out of the box (Plug&Play) Tier 1

e.      Trim lighting levels and sensor time outs using the OR App Tier 1 +2

f.        Set up logical zones and associations of offices lighting control, integrate to AV and BMS – Tier 3

g.       Cloud based, monitoring, reporting, schedules and building optimisation analytics Tier 4




Application Use Cases: 


The Organic Response Integrated Solution is one of ELA’s premium offerings for intelligent control.

The system affords a scalable offering from simple to more advanced lighting control. Install a future-proof-provision of Wireless RF communications to change functional operations, monitor, schedule and analyse. The use of a specific IR Remote to afford latent changes-configurations post installation. Changes that do not involve access to wiring or controllers inside the luminaires. Building owners can keep down operational costs associated without the maintenance of lighting and controls as need the need of specialist integrators is not required. 



How Organic Response works

Organic Response acts like a school of fish, where every individual communicates with its nearest neighbours. Each fixture has a sensor that responds to presence and daylight. Each sensor shares, receives and transmits information to the nearby light fittings. 

The Sensor Node

At the heart of the system is the Sensor Node. Integrated into each luminaire during manufacture, each Sensor Node contains a motion sensor, infrared transmitter, infrared receiver, ambient light and an intelligent microprocessor.

Here's how it works:

 The moment a Sensor Node detects occupancy, the luminaire responds by outputting a predetermined light level. It simultaneously communicates with its immediate neighbour luminaires using a Level 1 proximity limited wireless infrared signal, telling them it can see someone.

2. On receipt of this signal the neighbouring Sensor Nodes know that there is someone within one light fitting, and responds by outputting a predetermined light level appropriate to that occupancy profile. They simultaneously relay a Level 2 signal to their own neighbours, notifying them of the occupant’s relative proximity.

3. This propagates throughout the floor, creating the Occupancy Information Cloud. Each Sensor Node receives signals indicating how close someone is to it, and responds by emitting the appropriate light level based on the rich occupancy information it continually receives (and disseminates).

Wireless Distributed Intelligence 

4 - Distributed intelligence 

The result is comfortable lighting conditions around all occupants, lower light levels in areas adjacent to them, but importantly no wasted lighting of unoccupied or naturally lit areas. Once an area becomes vacant, each light gently dims to a low light state until the system is sure that nobody remains in the area. After this time, the lights switch off completely.

The system is completely plug and play, and intrinsically adaptable to changes in the layout of the Sensor Nodes or office. However, Organic Response can be highly optimised via a simple smartphone app. This allows individual luminaire settings to be easily adjusted for the specific needs of a particular occupant or environment.

For example, brightness can be trimmed and dwell times increased or reduced. In addition, using the same infrared peer-to-peer communication network described above relay configuration allows a whole floor to be configured with a new setting just by pressing a few buttons on the smartphone. With no training, electricians, facility managers, office managers or even each occupant has the ability to configure and optimise the system’s behaviour to suit their individual needs.


Optimise with your smartphone

With the app on your smartphone and an IR dongle multiple configuration options for each individual luminaire in the system can be made:
