Legacy amplifiers and loudspeakers could still be used, saving Houston Methodist considerable money while putting the infrastructure in place to convert failing components to Bosch Praesideo as the opportunity arose.

The first phase of the upgrade was to create a network, replacing relay-based analog signal routing by replacing existing signal processors with a Bosch Praesideo PRS-NCO3 network controllers and digital conversion hardware in each building.Ĭalls that were once missed were now getting through, solving the majority of problems with the system.

“The key is reliability and intelligibility, because a Code Blue call is literally life-or-death,” said Kenjura. Calls are routed according to priority, and are routed locally on the floor, within a building, or across the campus. There’s a Praesideo network controller and audio expander in each building. This nested architecture functions as the core for the distribution network.Īll the mission-critical campus-wide paging resides on the network, backed up by two redundancy networks, said Kenjura. These systems, in turn, are chained together based on which side of the street the building is located, essentially creating two primary control loops.Īn additional Praesideo system then connects all the buildings together to enable campus-wide calls. Walker Engineering’s approach was to harness each outlying building’s system by converting the audio signal to digital with Bosch Praesideo, enabling the system’s control network to work with the existing analog amplifiers and transducers. Houston Methodist’s goal was to allow system-wide call distribution while enabling floor-level and single-building traffic to function without losing any of the 1,700-plus daily PA calls. “Each existing building had its own legacy paging system, and the goal was to find an operational approach that could pull those patchwork analog systems into a modern digital environment, and do it without down time to critical communications,” he said.īosch Praesideo “has the flexibility and scalability to keep all these adjacent systems working throughout the transition,” said Kenjura. “We had previously upgraded several of the medical center‘s suburban facilities, but the downtown campus was a different kind of challenge,” said Matt Kenjura, manager of technology preconstruction for Walker, in the announcement. Walker recommended Bosch Praesideo digital public address and emergency sound system as a scalable, flexible enterprise solution to serve the new Walter Tower and unite it with the rest of the campus. “In keeping with Houston Methodist’s state-of-the-art approach to medicine, efficient communications across all 10 downtown buildings was a critical need,” according to a Bosch press release on the project.
