Fire Alarm systems notify with bright strobes and loud sirens. This is effective for alerting occupants of a problem, but not how to react. Mass/Voice Notification allows someone in authority to give verbal instructions to all persons in and around the emergency area. Prerecorded messages can also be triggered for standard announcements. Beyond fire alarm systems, voice notification systems can also be utilized for intruder alerts, severe weather conditions or any other situation involving public safety.
Will a regular paging system work? No. Since this is a life safety system it falls under the UL2572 Mass Notification Systems code. Many requirements are in place, including speaker and amplifier monitoring which ensures functionality.
Bosch Praesideo Digital Paging and Voice EVAC System has been
implemented in Europe for over 11 years. A network paging and emergency evac system has complete redundancy for processors and amplifiers with alert notification so if any piece fails, the good component will take over and alert you of the failure. Since it is networked, a page mic may be in Ohio while you're paging in Florida and Maine. A true global solution.
