Voice Alarm And Public Address System

What is EVC?

An EVC system covers a variety of functions, mainly for emergency use.

An EVC (emergency voice communication) system allows firefighters and others to communicate with one another during emergency situations. The system also allows communication with disabled persons.

It is a “System that allows voice communication in either direction between a central control point and a number of other points throughout a building or building complex, particularly in a fire emergency situation.”

What is EVC needed?

  • For conformance with national standards and building codes
  • To communicate with ‘emergency personnel’ within a building, to ensure a controlled evacuation
  • To communicate with ALL occupants within a building, to assist and reassure throughout an emergency
  • To communicate with occupants of ‘refuge areas

An EVC System is intended for use by:

  • Management of the building or complex, for the initial evacuation
  • The fire service during an evacuation
  • The fire service after an evacuation
  • Disabled / physically impaired people

One-way EVC System?

The primary purpose of the one-way EVC system is to enable announcements to be made, both manually and automatically to individual, or collective groups of zones, to facilitate a Quick and Orderly Evacuation of occupants in the building in an Emergency Situation.

The effectiveness of the Emergency Voice Communication System depends on the quality of the announcements. It shall be heard Loud and Clear. The building shall be zoned such that it shall be possible to make announcements to individual floor. Staircase cores may be group into one zone where appropriate


The Fireman Intercom Two-Way Communication System provides firefighting personnel with facilities for two-way communication that conform to Building Standards and Requirements.
