Police will carry out a monthly test of the Sydney CBD emergency warning system on Friday.
Officers will test some of the 98 speakers throughout the city, which display 13 variable messages, about 12.15pm.
"Members of the public who reside, work or travel through the Sydney CBD need to be aware of the warning system, what it sounds like and what it is used for," police said in a statement.
"The system is in line with similar warning systems overseas, where monthly tests are conducted to educate and remind the public of the existence of the warning system, and to ensure the system works."
