SINGAPORE - The Singapore Civil Defence Force (SCDF) will be sounding its Public Warning System sirens at 6.20pm on Monday (Feb 15), in support of Total Defence Day.
The Important Message signal will be broadcast through the islandwide network of sirens. It will last for a minute and members of the public are advised not to be alarmed.
When the signal sounds, local radio stations will play a brief message.
The annual exercise marks Singapore's surrender to the Japanese on Feb 15, 1942, during the World War II.
In the past, the exercise was held at 12.05pm.
In 2015, the SCDF changed the timing to activate the signal at 6.20pm - the historical time that the British surrendered to the Japanese.
