A Public Address (PA) System is a centralized system made up of loudspeakers, amplifiers, microphones, and audio switching matrixes used to broadcast alarms and provide voice paging to multiple or single areas of a facility using loudspeakers. The facility can be separated into zones or areas to enable the ability to specify which areas will receive voice or alarm notifications.
Having a PA System can be imperative in a large facility to provide the inhabitants of the building with notifications, important announcements, alarms, etc. Messages can be broadcast to either the entire facility at once, or to certain zones only.
The loudspeakers must provide clearly heard and understood audio signals. Certain industrial environments may require that the speakers be flame retardant or weather-proofed to ensure operational readiness in all conditions such as hazardous or noisy atmospheres. They can also be omnidirectional to transmit or receive messages from either end of the speaker. The system can be operated from a single control desk or multiple control desks.
Because amplifiers are built in over load protection circuitry, short-circuit protection, open circuit protection and thermal protection.
Messages can be pre-recorded in the event of an emergency to give specific directions to the entire facility quickly. This can be beneficial over the use of bells or traditional alarm sounds to provide specific instruction to people in any event. Spoken messages clearly identify the specific nature of the problem and provide clear instructions, while bells and alarms may cause people to panic. Messages can be used in the event of an emergency or to just to give general announcements.
JKS experts work with you to determine your facility’s specific PA system needs and engineers a system to accommodate them. We work with you from the planning phase through the implementation phase and perform regular maintenance to ensure your system operates at the highest level.
