Federal Signal PA300 Siren

The PA300 series of sirens 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.
