OmniDirectional Electronic Siren Series

Federal Signal's Modulator Series Siren, a family of electronic sirens, produces high intensity warning signals over a large area. A Modulator siren consists of an omni-directional speaker array and a siren control unit/battery cabinet (purchased separately - see the UltraVoice Electronic Siren Controller). A highly efficient design enables the siren to produce a high sound level, while making moderate demands on the battery power source.

The innovative Modulator Siren Series speaker array consists of modules that utilize four (4) 100-watt drivers per module. The Modulator is available in several models rated from 106 to 125 dBC at 100ft/30m.
