Please select an option.

The Federal Signal PA300 siren delivers exceptional value, time-tested durability, unmatched reliability, and is recognized worldwide as the industry standard.

This totally enclosed, fully featured siren will operate from any 12-volt negative ground vehicle electrical system. The PA300 can be powered directly by the vehicle’s battery or through secondary power distribution centers. No matter how power is delivered, the siren is protected against most failure modes, including reversed polarity, by a fuse that is readily available and can be replaced without tools. This PA300 series of sirens provides 100-watt output and will meet or exceed SAE J1849 and Class A requirements for sound when paired with a Federal Signal high-power speaker.

A wide range of features comes standard with any PA300 series siren. Included are 5 basic siren tones, TAP II (horn-ring transfer), PA, radio rebroadcast, and air horn sound with siren override. TAP II allows for effective intersection traffic clearing capability without removing your hands from the steering wheel or your eyes from the road. There is also a “Press-and-Hold” function, depressing and holding the horn ring will produce an alternate sound for as long as the operator keeps the horn ring circuit depressed. The siren’s PA volume level can be controlled with a rotary GAIN switch located on the unit’s backlit front panel, and radio rebroadcast volume is adjustable via an easily accessible rotary pot. The PA300 siren also includes a permanent noise-canceling microphone that produces high-quality voice reproduction without feedback squeal, and the microphone’s push-to-talk switch will override any siren tone for instant PA use.
