Federal Signal EOWS-408 [SiraTone]

SiraTone is a brand of electronic outdoor warning sirens produced by Federal Signal Corporation which began production in 1981. These sirens were designed to broadcast high-intensity warning signals over a large area. SiraTone products are/were used for natural disaster notification, HAZMAT incident notification, fire call systems, and more. Most of the SiraTone line was discontinued in the early 2000s and newer designs, like the Modulator and DSA (Directional Speaker Array), have replaced it.[1] The SiraTone product line is not in standard production, as of 2001. An exception to the rule, the EOWS* 612 speaker array was sold on request until around 2006-2007.
