New England Business Service's Flagstaff office serves as a order processing center for it's North America clientele. Phone and fax orders are received at this facility and processed at one of their printing and manufacturing plants located throughout the United States.
The building's major mechanical systems include:
|18 - Roof Top Units (Electric air conditioning/Gas heating)|
|Caterpillar Electric Generator|
This project involved controlling the 18 roof top units as well as monitoring the fire alarm system and the generator. The generator was designed to provide the facility with full electric power in the event that city power failed. This also includes the air conditioning and heating systems.
R. L. Shields Associates was the selected controls contractor and Delta Controls was the selected manufacturer.
The NEBS Corporate Facilities Engineer and R. L. Shields Associates established several goals to be accomplished with the completed system. These included:
A Delta Controls Intelli-Sys Control System was designed to accomplish these goals and provide NEBS with a comfortable, energy efficient work environment.
A Delta Intelli-Con Turbo Panel was installed in the Maintenance Office. The Turbo Panel monitored lighting, the fire panel, the generator and items such as outside temperature and humidity. Twenty-two Delta Controls Zone Controllers were installed to control the 18 roof top units. Five of the eighteen units had additional zone control dampers.
A Delta Turbo Panel is a multi-ported, memory enhanced, dual processor field panel. At NEBS - Flagstaff, a Personal Computer and a modem are to the Turbo Panel. This provides the operator with Color Graphics using 'Delta's IGraphW software. The modem allows off-site servicing of the system and provides NEBS Corporate Office in Groton, Massachusetts, the ability to monitor the building and make schedule and control changes. The modem also has the ability to page the maintenance personnel in the event of a mechanical problem requiring immediate attention.
Special software was written by R. L. Shields Associates, Inc. to accomplish several of the tasks designated as goals. Custom software included:
As previously mentioned, the Delta Turbo Panel is connected to a color host PC. The host system features Delta's IGRAPHW software. This "state-of-the-art" software package provides the user with both text information as well as providing a graphical interface. This software is also installed on the mechanical staff's personal computers to be used for off-site, after hours, operating changes. The maintenance staff has the ability to view all data and graphics from their home computers as they would see from their on-site computers.
Future phases of this project will likely include adding Carbon Dioxide sensors to monitor indoor air quality.
