PA300-100 is a compact, programmable siren available with self-contained controls. PA300-100 is easy to install and incorporates Convergence Network Configuration Software to provide a high-level of customizable control capability. Convergence Network Configuration Software is available as a download from the Federal Signal website making it easy to program one vehicle – or an entire fleet – from your laptop. 

Controller Features 
The control faceplate includes a seven-position rotary switch, volume control, speaker diagnostics, and (2) backlit buttons. The buttons are programmable and can be programmed for press-on, press-off, momentary, and multiple different blinking styles. The button brightness can be dimmed or turned off for stealth operation. Button color can be programmed through the Convergence Network Configuration Software and can be programmed in Red or Blue. 

PA300-100 is designed to detect speaker faults. The diagnostic LED is available on the front of the keypad and is fully programmable. Diagnostic LED can be set to steady burn or flash when the siren detects a fault or normal operation for the speaker.

Amplifier Features 
PA300-100 default siren tones include wail, yelp, priority, HI-LO, and air horn. A library of other selectable siren tones is available in the software. PA300-100 also includes two serial ports to be used with FS Convergence Network devices such as light bars or directional warning lights for easy “plug-and-play” installation. Other features include horn ring transfer, public address with included microphone, and radio rebroadcast. 

PA300-100 has connections for four general-purpose input circuits, plus dedicated inputs for park, horn, and ignition. Ignition is an active-high only input, while all other inputs are programmable for active-high or active-low. 

Programming Software Features 
The Convergence Network Configuration Software is available as a download from the FS website and siren configurations can be created via laptop computer. Configured programs can be extracted, modified, and stored for ease of service and reuse. The Federal Signal Convergence Network allows the user to “plug-and-play” simply by connecting the siren to the vehicle’s light bar. PA300-100 gives the user the ability to clone an entire fleet of siren functions. The user simply connects the PA300-100 to a PC and downloads the functions of the programmed software onto a USB drive to download functions to each siren.

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 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.
