Douglas Lighting Controls (MC-6000) Replacement

Customer office tower had an existing Douglas MC-6000 based Lighting  Control system that was installed in the mid 90's and has been unsupported since the early 2000's.  Over time the customer was forced to hard-wire various lighting loads to maintain lighting along with consuming energy 24 hours per day.  Recognizing that this was problematic and wasteful, could not continue various upgrade solutions were considered with a mainstream lighting vendor selected to perform the upgrade.  However, the overall cost, extensive deployment/commissioning delays, inadequate support, and the need to use/support a proprietary control architecture stimulated the customer to halt further upgrades beyond what was committed.  S2 was engaged and identified that the S2BACLightDP would be a very cost effective, quick to deploy, provide direct support for the existing Douglas switches, and could be directly integrated into the building's Bacnet based BMS  (no need for proprietary software).  After a successful smaller evaluation project, the customer committed to using S2 and the S2BACLightDP for numerous other Douglas Lighting Panel upgrades that their yearly budget would allow.  

• All existing Douglas based lighting controllers were replaced with the S2BACLigjhtDP controllers while maintaining all of the existing electrical infrastructure including the cabinets, wiring, conduit, and even the very old, but working early Douglas 2-wire relays (WR6321).
  

• Should the existing old Douglas relays become problematic, S2 can provide a very cost effective solution to upgrade the existing lighting panels to use the latest 2-wire lighting control relays.

• Should the existing Douglas Switches become problematic, S2 has several direct replacement Douglas switch compatible options to suit the customer's budget and aesthetics.

• Should the customer wish to include 0-10V or Dali dimming and control capability, S2 has expansion products to suit this functionality.

• S2 worked with the base building electrical, controls, and networking contractors to ensure that all of the customer's connectivity requirements (topology and Cybersecurity) were followed.  Customer requires all new building controllers to be Bacnet IP based which the S2BACLightDP has direct onboard support for. 
  

• After working with S2 regarding the BMS integration, the base building controls contractor created a BMS framework and "template" to allow rapid integration of the S2BACLightDP controllers into the BMS.  The result was that each of the Douglas lighting panels could be upgraded and BMS integrated at a rate of one per every 1.5 hours.

• Once all of the Ethernet networking was installed, S2 and the electrical and controls contractors were able to upgrade and BMS integrate seventeen (17) Douglas Lighting panels in just over 2 business days which is unprecedented with any other lighting control upgrade solution.

• In contrast to the original installation, S2 has provided the customer and their base building contractors complete and thorough S2BACLight documentation, configuration software, and reports detailing all of the lighting panel relay load descriptions and electrical circuit numbers.

• Project cost was substantially less (1/3) than the previous upgrade solution, but with more features, functionality, and direct BMS integration and in so doing allowing the customer to self maintain or use their preferred base building contractor for ongoing changes.

• Customer has recently committed to upgrading all remaining Douglas Lighting panels with the project starting (and completing) this Spring (2025)
