Red Color

When the signature of a rocket launch is detected, the system automatically activates the public broadcast warning system in nearby Israeli communities and military bases. A recorded female voice, intoning the Hebrew words for Red Color ("Tzeva Adom"), is broadcast 4 times. A intermittent tone with 2-second intervals between sound and pause is transmitted after the pre-recorded female voice in case the missile attacks do not cease after a certain time. The entire alert system is repeated until all rockets have been shot down and no further launches are detected. The system was installed in Ashkelon between July 2005 and April 2006. Up to June 2006, the announcement was called Red Dawn (transl.: Shakhar Adom) but it was changed to the Hebrew words for Red Color (transl.: Tzeva Adom) due to a complaint made by a 7-year-old girl named Shakhar (Hebrew for dawn). It was the subject of a documentary, which focused on how children are to cope with an alert, directed by Yoav Shoam. Since 2014, alerts have been available as an app on iPhone and Android from the App Store and Play Store. It was the most downloaded app in Israel in July 2014 during Operation Protective Edge. Users can select to receive alerts for rocket attacks nationwide, or only in their districts. • Illustration — Red Color (Tzeva Adom) alarm and Gazan Qassam rocket attacks on Sderot, Israel – 2007 In October 2023 it was reported that a version of the system modified to suit Ukraine "would start working in Kyiv soon" to warn against the Russian missile strikes of the Russian invasion of Ukraine.
