“Since 9/11, much closer attention has been paid to life safety systems,” said Steve O’Rourke, audio division manager of Backman Vidcom, the Canadian integrator responsible for installing the plant-wide public address system.
“Along with security, fire protection and rescue systems, the PA system has an extremely important role in plant safety. People need to be able to hear announcements and alerts clearly – it can be a matter of life and death in an emergency situation.”
The Point Lepreau Nuclear Generating Station system includes 18 Crown CTs Series CTs 8200USP/CN power amplifiers with CobraNet networking cards and 32 Crown CTs 2000 amps with PIP3 card connectivity.
“This gives us a total of 208 channels and 92,800 watts of power. “We needed the networking capability the Crown amps provide because we designed the installation to be a completely self-monitoring system.”
Since the previous PA was 30 years old it needed to be completely replaced. “This gave us the opportunity to take advantage of the latest advancements in amplifier and speaker design and system control. What the plant needed was a ‘Voice of God’ PA that could reliably deliver pages all day long and could be clearly heard for any alert and emergency situations that might occur. It had to be intelligible even over the adverse noise conditions that occur in a large industrial complex,” O’Rourke stated.
Equally important, the system absolutely had to keep functioning during emergency situations and had to be CSA (Canadian Standards Association) certified and assembled to nuclear-grade standards. For these reasons O’Rourke only used most reliable components and built in a level of redundancy so that the PA would keep working even if parts of it incurred physical damage.
