EOIR contracted with GTI to install and maintain a new public address (PA)/paging system in their four-building headquarters complex outside of Washington, D.C., to allow instant PA communication with all employees regarding routine and emergency situations. EOIR needed stand-alone, direct-paging access and the ability to announce pages from outside the complex—via a secured dial-in connection. This would ensure operability of the PA system in the event of PBX access failure. Task assignments included all planning, project management, equipment acquisition, and installation services.

GTI designed, engineered, and installed a multi-zone PA system that utilized the existing 56-zone distributed-amplifier solution and built upon that controller's expansion capabilities, allowing paging to a single floor or group of floors and/or to the outlying buildings within the complex. In order to provide coverage in all required areas, the system consisted of 13 100-watt digital amplifiers, two 20-watt digital amplifiers, 441 ceiling-mounted speakers, six wall-mounted speakers, and one horn. In addition, GTI installed 14,000 feet of plenum-rated 18-gauge speaker wires in support of this configuration.

GTI's ability to integrate its solution with the existing paging controller (installed the previous year) gave EOIR a significant cost-savings benefit by not having to purchase an entirely new PA communications system. Speaker installation was accomplished after hours and over weekends, to minimize disruption of EOIR's day-to-day business activities. All work was performed on schedule and was ready for operation in full compliance with all contract requirements.
