Direct LV works across Automated Logic (ALC), Trane, Johnson Controls (JCI), and other major BAS/DDC platforms—from low-voltage field wiring and controllers to BACnet networks and the building automation front end.
Professional DDC installation, startup, troubleshooting, and commissioning for commercial HVAC systems. Direct LV works across Automated Logic (ALC), Trane, Johnson Controls (JCI), and other major BAS/DDC platforms—from low-voltage field wiring and controllers to BACnet networks and the building automation front end.
Commercial HVAC equipment only performs as intended when the controls sequence, field devices, wiring, controller, and network work together. Direct LV installs and services the complete DDC path—from sensors and actuators in the field to the controller, BACnet communication network, and building automation system.
We work from project drawings, point lists, and sequences of operation to install, terminate, test, and verify each required control point. That includes new construction, tenant improvements, replacements, and upgrades to operating buildings where the existing platform and equipment must be understood before changes are made.
Whether the system uses Automated Logic (ALC), Trane, Johnson Controls (JCI), or another major BAS/DDC platform, the goal is the same: accurate inputs, reliable outputs, correct equipment response, and clear documentation of what was verified.
Installation, routing, labeling, and termination of low-voltage control wiring for field devices, equipment interfaces, and control panels.
DDC controller mounting, termination, panel assembly, power checks, relay interfaces, terminal identification, and panel cleanup.
Sensors, thermostats, actuators, control valves, dampers, VFD interfaces, safeties, and other field devices connected and checked against the intended sequence.
BACnet communication wiring, controller addressing support, network troubleshooting, and integration work for compatible building automation systems.
Every input and output is traced from the field device through the DDC controller to confirm point identity, signal accuracy, command response, and final equipment action.
Functional testing against drawings and sequences of operation, issue documentation, corrections within scope, and verification before handoff.
We review drawings, point lists, sequences of operation, equipment, platform, access needs, and the field conditions that affect installation.
Controllers, panels, field devices, low-voltage wiring, and equipment interfaces are installed and terminated to the approved project requirements.
We verify point-to-point operation, inputs, outputs, communication, and equipment response while coordinating with the project team as needed.
The completed work is functionally tested against the sequence of operation, deficiencies are documented, and verified control points are handed off clearly.
Direct LV has experience working across Automated Logic (ALC), Trane, Johnson Controls (JCI), and other major BAS/DDC systems. Before work begins, we verify the specific platform, controller family, access, protocol, and project scope.
DDC & Building Automation across Metro Detroit, Michigan and the surrounding communities in Macomb County, Oakland County, Wayne County. If your city is not listed, call us — chances are we cover it.
Tell us what the building is doing and we will tell you what it needs. Walkthroughs and quotes come before any work starts.
