Value and Unmatched Reliability
The PA300 siren delivers exceptional value and unmatched reliability. This siren can provide either 100- or 200-Watt output to 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
A wide range of features comes standard with any PA300 police 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 having to remove 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.

Noise-canceling Microphone
The PA volume level can be controlled with a rotary GAIN switch located on the unit’s backlit front panel. 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 push-to-talk switch will override any siren tone for instant PA use.


Electrical System
The enclosed, fully-featured siren operates from any 12- or 24-volt negative ground vehicle electrical system. The PA300 can be powered directly by the car’s battery or through secondary power distribution centers. No matter how power is delivered, the PA300 siren is protected against most failure modes, including reversed polarity, by a readily available fuse and can be replaced without tools.

Compact Size
PA300 siren packages are built small and compact, and each unit comes supplied with its own “U” shaped mount bracket. There are no protruding components to interfere with mounting arrangements, and all electrical connections are easy “plug-and-play” types located on the rear of the siren’s housing.

Mounting Options
An optional stainless steel bezel is available for flush mounting and a wide variety of switch controls that flush mount to the PA300 series siren are also available.

Important Warning for Police Boats and Fire Rescue Boats

It has come to our attention that police boat and fire rescue boat sirens and speakers may subject persons operating those craft to sound pressure levels that can cause permanent hearing loss. We recommend that speakers be located as far forward on the boat as possible, as recommended in the SAE Recommended Practice J1849 "Emergency Vehicle Sirens". However, unprotected exposures of a sufficient duration to properly located siren speakers can still create a risk of hearing loss.

It is our recommendation that your siren speakers should be relocated and persons operating these craft should wear hearing protection when using the siren system.

Failure to comply with these recommendations may result in temporary or permanent hearing loss to operators and passengers of these vehicles.
