Bob Harkins Library

In 2017 we worked with the Bob Harkins Library on a DDC upgrade in order to upgrade their controls and replace most of the existing installation by a previous contractor. This required using what we could from the previous install and integrating our new hardware to create a more streamlined and easy to manage system. Once complete, our graphics team created a customized graphics package that will allow the Library to monitor and control their building's systems from one location.
