SiraTone is a defunct brand of electronic outdoor warning sirens produced by Federal Signal Corporation which began production in the early 1980s. 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. [1] The SiraTone product line is no longer in production. The product line was succeeded by the Modulator and DSA (Directional Speaker Array) electronic outdoor warning sirens. [2]

Products

Six models of outdoor warning sirens were produced under the SiraTone brand. Model numbers are designated by the lettering EOWS (Electronic Outdoor Warning Siren) and an asterisk, followed by a number representative of the respective siren's decibel output or speaker array setup. All models utilize re-entrant speaker horns, arrays of 100 watt speaker drivers, and produce six standard signals.

There was also a mobile vehicle-mounted version, at one time, called the EOWS* M12. However, likely none were made.

Signals

The sirens are able to produce these tones:

A unique feature of the SiraTone siren series was the ability to conduct routine tests with a Westminster Chime melody instead of an actual alarm tone, intended to be a more pleasant alternative to the use of actual alarm tones. This allows operators to test sirens without fear of public panic and still ensure siren speakers are fully functional. Various other signals could be added upon special request. [11]
