SCDF will be sounding the “Important Message” signal through the island-wide network of Public Warning System (PWS) sirens on Friday, 15 September 2023 at 6:20pm. Do not be alarmed by the minute-long sounding exercise.

The signal will also sound for all smartphones that have the SGSecure mobile app downloaded and are not on silent or vibration mode. The signal will stop once the message is acknowledged or cease after 20 seconds. This will be followed by a brief text on the PWS sounding.

When you hear the “Important Message” signal, tune in immediately to any local radio station or free-to-air TV channel for a brief message on the PWS. If you miss the message, visit go.gov.sg/pws to know more about the PWS signals.

Held annually, the sounding and broadcast message are part of SCDF’s continuous efforts to familiarise the public with the PWS signals and to raise awareness on how the public should react upon hearing the signal.

To prevent any undue public alarm, we seek your assistance to carry the above information in your news bulletins to remind the public on the sounding.
