An overriding challenge was not only bringing the specification up to speed but also determining where to place access control readers due to the large number of elevators in the facility. “It’s difficult to test wireless locks when you don’t have a final structure in place,” Doan said. “We used PIN modules to transmit to the wireless locks and back to the controller. We had to be sure the door locks would communicate properly,” he said.
Siemens handled integration into the new onsite command and control center and tied older analog cameras (although new surveillance is IP) into the control center with encoders.
“It was critical to do a lot of consulting work with the hospital, and that’s definitely where we excelled,” Doan said. “Sometimes it meant a change order and that wasn’t initially well-received but it saved headaches down the road,” he said. In addition to installing some 300-plus IP cameras, mostly Sony and some Arecont, Siemens also installed some 650 wireless door readers (Ingersoll Rand Security Technologies Schlage AD-400); 350 hardwired door readers from HID and also integrated new IP cameras to the American Dynamics (a Tyco International Co.) victor video management system that enables users to use both analog and IP cameras and provides a single solution to manage recorded video from VideoEdge NVRs.
Siemens Industry Inc. has been on the job since about 2009 and over the last year has spent about 1,800 hours at the hospital’s construction site, with about five technicians on the job.
