General Description
Introduction
Federal Signal Modulator Series siren products are a family of electronic sirens capable of
producing high-intensity warning signals over a large area. The siren consists of a speaker
array and Control and Battery Cabinets. A highly efficient design enables the siren to
produce a high sound level while making moderate demands on the power source.
Modulator models purchased after September 2017 are preconfigured to support top and
side lights kits for visual signaling options that can enhance the proven technology of the
Modulator’s intelligible voice communication and signaling.
Federal Signal omni-directional, electronic Modulator Series siren consists of aluminum
modules that use four 100-watt drivers per module. The Modulator series B is available in
several models with the following sound output rating at 100 feet.

The Modulator Series siren provides a virtually flat frequency response from
200-2000 Hz. This gives the siren the ability to produce loud and clear voice messages
and produce a full spectrum of warning tones.
An UltraVoice® Controller (Model UV) is needed for complete operation.
