Lehigh Career and Technical Institute
Situation
LCTI, located in Schnecksville, PA, is one of the largest technical schools in the country. The institute houses individual classrooms and large lab settings for teaching a wide variety of technical and industrial trade classes. LCTI needs to be able to contact students and faculty in the classrooms and lab areas with public address announcements as well as time coordinated tones for the start and end of classes.
Analysis
LCTI needed a way to communicate with these individual classrooms, lab areas and corridors with mass notification in the whole building and campus buildings. The system will require the take-over and control of speakers connected to individual sound systems used in the cafeteria and restaurant areas. These public address announcements needed to be coupled with a synchronized clock and coordinated time tone signaling system.
Solution
ETI proposed a solution to replace the existing paging system with an individually addressable public address system. This system allows for individual classroom communication as well as multi-zoned public address announcements. The solution also accommodated the low power requirements of the individual classroom speakers as well as the high power requirements of the lab and corridor speaker areas. The communications system allowed for mass notification to all areas and all campus buildings, including the individual sound systems of the cafeteria and restaurant areas. The system also included a redundant system as a back-up, should the microprocessor system fail. The communications system was integrated with a campus-wide synchronized corrective clock system and time coordinated tone signaling system. Finally, the system was interconnected to the LCTI’s voice over IP telephone system to allow classroom, lab, and mass notification announcements to be made directly from the administration staff telephone sets. This system solution added to the security and safety of the students attending LCTI.
