Fire Alarm Systems:
Fire alarm systems are used to provide notification to building occupants, notify local first responders or interface with various other life safety and building systems by use of automatic detection and manual means of activation during an emergency.
Mass Notification/Emergency Voice Systems:
A mass notification system provides occupants with information and instructions about emergency conditions in a building, area site, or other spaces. The objective of a MNS is to protect life by indicating the existence of an emergency situation and instructing people what actions they should take through concise, accurate, timely, and well-directed messages. These systems are typically used in military or campus type facilities.
