Pathfinder® PF400 is a 400-Watt, programmable siren and light controller available with remote surface-mount controllers or handheld controller. Pathfinder PF400 is packed with features such as multi-tone and Rumbler traffic-clearing capability, along with optional On-Board Diagnostics (OBDII) integration. Pathfinder PF400 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
Pathfinder PF400 provides the user with customized control of the siren, warning lights, directional lights, and other accessories. Pathfinder PF400 can control the SignalMaster™ directional functions in light bars, ILS systems and “stick” lights that are compatible with FS Convergence Network as well as Latitude™ 3-wire SignalMaster. For convenient visual reference, the Pathfinder PF400 emulates the selected pattern of the SignalMaster operation.

All controller options feature programmable buttons that can be programmed for press-on/off, momentary, timed, step-thru and multiple different blinking styles. The button brightness can be dimmed or turned-off for stealth operation. Over (100) labeling stickers, such as alley, gun lock, and wail allow for further customization of the controller.

Button color can be programmed through the Convergence Network Configuration Software. The remote models can be programmed in dual-color (Red/Blue) while the Handheld and 17-button can be programmed in nine different colors - Red, Blue, Green, Cyan, Magenta, Yellow, White, Purple and Amber.

Integrated Rumbler® and Multi-Tone Capability
The Pathfinder PF400 is available with integrated Rumbler traffic-clearing capability. This allows the Pathfinder PF400 to produce a Rumbler tone without the need for a separate externally mounted amplifier. Rumbler capability requires the purchase of Rumbler speakers and vehicle-specific mounting kit.

Pathfinder PF400 provides the ability for single-, dual-, tri-, or quad-tone capability depending on the amount of speakers used. The Pathfinder PF400 is capable of doing dual-tone and Rumbler in a single amp.

FS Vehicle Integration/On-Board Diagnostics Integration (OBDII)
The FS Vehicle Integration is a simple plug-in connection using the existing vehicle CAN bus system. 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 use of the FS Vehicle Integration removes the need to separately wire certain options such as horn ring transfer or ignition (vehicle-type dependent).

Timer Feature
The Pathfinder PF400 built-in timer feature senses ignition ON/OFF and allows the selection of multiple time settings. Various devices can be wired to relay outputs on the Pathfinder amplifier (such as in-car video DVRs, radios, and laptop chargers), and a security timer can be programmed to minimize the possibility of unauthorized gun release. Pathfinder PF400 timer feature allows the end user to avoid the extra cost of an external timer per vehicle by allowing each device to be turned off at a different time, unlike many one setting external timers currently in the market.

Amplifier Features
The Pathfinder PF400 produces Wail, Yelp, Priority, and an Air Horn sound by default. The horn-ring transfer feature enables the driver to control siren tones as well as patterns by pressing the horn button. A library of other selectable siren tones are available including Unitrol™ branded siren tones such as Wail, Yelp, Futura, Hi-Lo, Ultra Hi-Lo, Alarm, Air Horn, and Hetro. PA, radio rebroadcast, and Air Horn are standard in the Pathfinder PF400. Pathfinder PF400 also includes (4) serial ports to be used with the FS Convergence Network devices such as light bars or directional warning lights for easy “plug-n-play” installation.

The Pathfinder PF400 has sixteen solid-state relays: ten-ampere high and six five-ampere high, and four 500 mA low. The maximum output current for each relay can be set with the Convergence Network Configuration Software.

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 re-use. The Federal Signal Convergence Network allows the user to "plug-and-play" simply by connecting the siren to the vehicle’s light bar. Pathfinder PF400 gives the user the ability to clone an entire fleet of siren functions. The user simply connects the Pathfinder PF400 to a PC and downloads the functions of the programmed software onto a USB drive to download functions to each siren.

Pathfinder PF400Q / PF400 Recommended Configurations 
The Pathfinder PF400 can drive one to four 100-Watt speakers. The PF400 is capable of multiple speaker and tone configurations. Pathfinder PF400 can also be used in 100-Watt applications and still meet SAE J1849 and NFPA Compliance. Please download the data sheet for recommended configurations.
