A Mass Notification System must be able to:

• Provide an alert to the population as quickly as possible
• Alert and inform people in multiple areas
• Provide door lock-down for vulnerable or targeted areas
• Provide communications under conditions such as a downed telephone service.

Zenitel products provide the voice for these systems, with a range of Intercom and Public Address solutions that enable both 1 way and bi-directional communication between the Control Room and the public.  High power Amplifiers and alarm speakers provide very high sound pressure levels to distribute announcements over vast distances. Interfaces such as SIP allow disparate systems such as the Telephony system to be included in these audio announcements.
