![]() Fedelcode sirens came with the option to add a coding damper, which used a motor-driven (early) or electromagnetic (later) damper to block and unblock the siren's intake, allowing it to produce a "pulse" of noise. The Fedelcode was designed with a very steep cowl, or "skirt" to project sound downwards and be dispersed by a building roof, as roof mounts were the most popular mounting style at the time. The designs included a weatherproof housing to prolong the life of the siren inside. Single rotor Fedelcodes came in three main sizes, the C1 1/2, C2 1/2 (or B2 1/2), and C3 1/2. Unlike the later Model series sirens, Fedelcodes came in a wide variety of shapes and sizes throughout the years. These sirens were designed to replace the antiquated Type B, which had lackluster performance. The user simply connects the PA4000 to a PC and downloads the functions of the programmed software onto a USB drive to download functions to each siren.The earliest sirens in the Model series began production in 1929 as the Fedelcode series, manufactured by the Federal Electric Company. PA4000 gives the user the ability to clone an entire fleet of siren functions. Configured programs can be extracted, modified, and stored for ease of service and reuse. The Federal Signal Convergence Network allows the user to "plug-n-play" simply by connecting the siren to the vehicle’s light bar. The Convergence Network Configuration Software is available as a download from the Federal Signal website and siren configurations can be created via laptop computer. The use of the FS Vehicle Integration removes the need to separately wire certain options such as horn ring transfer or ignition.įor a full list of vehicles, visit Programming Software Features The FS Vehicle Integration uses a vehicle specific cable (sold separately) to seamlessly integrate with the vehicle allowing light and siren control with vehicle events such as door open, headlight, brake, speed, park, etc. The FS Vehicle Integration is a simple plug-in connection using the existing vehicle CAN bus system. Dual-tone capability cannot be utilized with the Rumbler capability unless a complete RUMBLER-3, which includes the additional amplifier, is purchased.įS Vehicle Integration/On-Board Diagnostics Integration (OBDII) Rumbler capability requires the purchase of Rumbler woofers and vehicle specific mounting kit. This allows the PA4000 to produce a Rumbler tone without the need for a separate externally mounted amplifier. The PA4000 is available with built-in Rumbler® Traffic Clearing capability. PA4000 also 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. The maximum output current for each relay can be set with the Convergence Network Configuration Software. ![]() The PA4000 has 12 solid-state relays: five 10 A active high solid-state relays, one 10 A high-low, and six 5 A high. Other features include horn ring transfer, public address with included microphone, and radio rebroadcast. PA4000 also includes two serial ports to be used with FS Convergence Network devices such as light bars or directional warning lights for easy “plug-n-play” installation. A library of other selectable siren tones is available in the software. PA4000 default siren tones include wail, yelp, priority, and air horn. By default, the diagnostic LEDs are disabled but can be programmed with the Convergence Network Configuration Software. The LEDs are fully programmable and can be set to steady burn or flash when the siren detects a fault or normal operation for each individual speaker. Button color can be programmed through the Convergence Network Configuration Software in Blue or Red.ĭiagnostic LEDs available on the front of the controller can provide the operating status of each of the amplifier outputs. The button brightness can be dimmed or turned-off for stealth operation. The two programmable buttons can be programmed for press-on, press-off, momentary, and multiple different blinking styles. The design of the PA4000 siren system is ideal for use in ambulances, police cars, fire apparatus and command vehicles.Ĭontroller features a seven-position rotary switch, two programmable buttons, volume control knob, speaker diagnostic LEDs, and microphone. ![]() The PA4000 is a full-featured, programmable, electronic siren and light control system with a remote-control head that can be flush mounted to any flat surface. ![]()
