Red Color - Wikipedia, the free encyclopedia: "The Red Color (Hebrew: צבע אדום, transl.: Tzeva Adom) is an early warning radar system installed by the Israel Defence Forces in several towns surrounding the Gaza Strip to warn civilians of imminent attack by rockets (usually Qassam rockets).[1]
The system currently operates in a number of southern Israeli cities within range of missiles fired from the Gaza Strip, including Ashkelon and Sderot. When the signature of a rocket launch is detected originating in Gaza, the system automatically activates the public broadcast warning system in nearby Israeli communities and military bases. A two-tone electronic audio alert (with a pattern of high, 2 second pause, high-low) is broadcast twice, followed by a recorded female voice [2] intoning the Hebrew words for Red Color ('Tzeva Adom').[3] The entire program is repeated until all rockets have impacted and no further launches are detected. In Sderot, it gives residents approximately 15 seconds' warning of an incoming missile.[3]"
