The Federal Signal PA300 siren delivers exceptional value, timetested 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.  The PA300 series of sirens can provide either 100- or 200-watt output and will meet or exceed SAE J1849 and Class A requirements for sound when paired with a Federal Signal high-power speaker.
