The installation and commissioning process in the lighting industry has always been unpredictable. Things go wrong, and unprecedented challenges come up while solving an issue. Only experienced professionals like Sigma Tech 360 can be trusted to solve any problem reliably and efficiently because we have the required expertise and solutions. When we say, "We've done the hard work, so you don't have to", we mean it, and this case study is yet another example!

The Issue

The customer was seeking to install wireless lighting control at their facility. When Sigma Tech 360 started the installation and commissioning process, we discovered that predetermined wiring points between the canopy and reception were causing connectivity issues. The canopy had connection points well away from the reception area, and due to site conditions, Bluetooth communication for controlling lighting fixtures was sporadic. This severe connectivity issue would normally have been challenging for Bluetooth mesh networks but was easily resolved using our Unite Bridge module.

The Solution

Sigma Tech 360 utilised a mixture of DMX and DALI-controlled fixtures to enable wireless lighting control of the reception and canopy lighting for our customer. Mixing and matching lighting control protocols allows the use of a single product to control any of the protocols on site without the need for separate modules for each protocol.

Sigma Tech 360 supplied 2 x Unite Bridges to resolve the customer's connectivity issues utilising the Islands of Bluetooth concept unique to us. We ensured the customer can now control all of their fixtures effortlessly from the reception as desired.

Sigma Tech 360 used DMX wall fixtures which are RGBW colour changing since the customer wanted to change the colour of the fixtures individually. They also desired to set scenes of colour for different occasions, so RGBW colour-changing fixtures were perfect for their needs.

The Issue

The customer wanted a single point of control for all the lighting fixtures in the Atrium. It had to be through an iPad or online, even though the unusual nature of the distributed lighting scheme made this difficult to implement. Due to the specifics of the Site, Bluetooth communication with the Atrium was not possible.

Sigma Tech 360 had to devise a special connectivity arrangement to meet the customer's requirements. Our Unite products provided a unique solution to solve this problem. Using a 4G router and a remote antenna with an extension cable, we were able to achieve wireless communication and control between all the UMPs.

The Solution

Sigma Tech 360 controlled 44 DMX colour-changing light bars along with 16 on-off-only floodlights. We used four UMP modules, each controlling 11 DMX fittings in the atrium. To control 16 floodlights with simple schedules, one UMP is installed, having a built-in relay. The control is done locally on an iPad or remotely through the cloud.

Four modules and the master node are positioned in the atrium to control the DMX light bars. In contrast, the module for the floodlights was positioned 15 meters away in a separate electrical riser. The UMP has the ability to attach a remote antenna. Sigmatech 360 supplied a 15-meter extension cable for the remote antenna to be positioned in the atrium enabling communication between all the Master Node and other UMPs.

The fixtures are controlled locally using a tablet, or remotely via cloud services enabled by the master node connected to a 4G router.
