Don’t be alarmed when emergency sirens ring out from 65 CBD locations as part of a test of Melbourne’s new emergency warning system on Tuesday morning.

The warning, which will include a recorded message that states it is a test, will run for about five minutes.

It follows a demonstration of the public address system from the State Library of Victoria in December.

A car drives in circles outside Flinders Street Station shortly before pedestrians were hit.

“If you hear the test alert or notice an enhanced police presence in the CBD tomorrow (Tuesday) morning, there is no cause for panic,” Assistant Commissioner Stephen Leane said.
