Introduction

Federal Signal Modulator Series siren products are a family of electronic sirens that are
capable of producing high-intensity warning signals over a large area. The siren consists
of a speaker array and Control/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.

modules that use four 100-watt drivers per module. The Modulator series B is available in
several models, which have the following sound output rating at 100 feet.
The MOD6032B is a 3200-watt siren that uses the MOD6024B siren configuration. The
middle two modules use eight 100-watt drivers.
