  • Federal Signal’s Modulator II Siren offers the same proven technology as the original Modulator with the exception of a smaller compact chassis.

    Modulator II provides a flat frequency response up to 2000Hz producing intense warning signals and digital voice messaging over a large area. The Modulator II design enables the siren to produce a high sound level and intelligible voice communications.

    The innovative omni-directional electronic Modulator II speaker array consists of modules that uitilize four 100 watt drivers. It also provides clear voice communication and offers warning signals which are produced by Federal Signal’s UltraVoiceTM electronic controller and amplifier system. Custom tones and professionally recorded voice messages for the UltraVoice controller are available and can be purchased upon request.

    The Modulator II siren combined with the UltraVoice controller is ideal for community/municipal, industrial and military applications where immediate instruction is necessary. The MOD6032 and MOD6048 have been replaced by the MOD8032B, which is shorter, lighter and more compact.
