14.0 Mass Notification System
Introduction
The MMX Mass Notification System (MNS) allows announcements and notifications outside of
regular fire announcements. For example, MNS can be used for weather warnings or toxic
chemical alerts, and these announcements have a higher priority than fire announcements.
The fire control system can also override the MNS.
The MNS comes with a fire control and monitoring system. A single MNS panel can display
both MNS and fire events, but each type of event appears separately on different annunciator
displays. The fire and mass notification modules on the MNS panel are arranged
independently of each other and are accessed by two separate doors. Refer to Figure 66.

14.1 Virtual Zones
A virtual zone is a zone that is not associated with any physical devices but instead monitors
inputs across groups and activates outputs across groups using advanced logic.
