Shiratech EN54-16 Emergency Sound System is a public-address audio equipment that provides evacuation information and instructions through loudspeakers placed inside the building. Building areas are divided into zones; each zone is fitted with a group of loudspeakers that is feeded by a dedicated line. The EVAC receives inputs from the main fire control unit and forwards a recorded or a live spoken message in those zones subject to fire alarm.

Audio path management is achieved through a switch matrix that routes the sources to each zone accordingly to user inputs or commands from fire alarm unit.


Shiratech voice alarm system is certified on EN54-16 Standard by a notified body. A list of all notified bodies can be found on EU institutional websites.

The certificate released by the notified body contains:

• Certificate number

• Approved system components

• Approved options


The indication of approvement is the certificate number that shall be visible on the main parts of the system and in the accompanied documents.
