CHAPTER 2
An Overview of the Pathfinder
The Pathfinder siren is a full-featured, programmable electronic siren and light control system. State-
of-the-art microprocessor technology is used to create a system with a small, compact siren system
that can be installed under the dashboard (PF200, Self -Contained), in the trunk or under the seat
(PF200R, Remote) of any vehicle with a 12 V or 24 V negative ground system. The Pathfinder siren
uses class D amplifier technology to provide two independent 100W channels of audio, for a total
of 200W, without the need for a large and heavy transformer. The module provides the automatic,
simultaneous light and siren activation required by some jurisdictions. A security gun timer is also
provided to minimize the possibility of unauthorized shotgun release. The module has two easily
accessible Convergence Network serial ports that can connect a remote mounted control head and/
or any serially-controlled Federal Signal product. The siren also has FS Vehicle Integration to allow
for various events a vehicle to integrate with siren/lighting control. A variety of system features
can be programmed with the Convergence Network Configuration Software from a computer via a
USB cable that connects the siren amplifier. System features include flash patterns, siren tones, and
momentary, push-on/push-off, timed relay operation, as well as vehicle events. Programming does
not require disassembling or removing any hardware from the vehicle.
Siren, PA, and Speakers
The Pathfinder produces wail, yelp, priority, and as well as an air horn sound by default. The horn-
ring transfer feature enables the driver to control siren tones by pressing the horn button. Public
address is available with the Federal Signal microphone, which is included with the system. Radio
rebroadcast is also available. The Pathfinder can drive one or two 11-ohm impedance, 100 W
speakers. The two 11-ohm impedance, 100 W speakers have separate wires that allow the Pathfinder
to provide dual siren tones. Alternatively, the Pathfinder can drive one 11-ohm impedance, 100
W speaker on one channel, and two Rumbler speakers on the second channel to provide Rumbler
integration, without the need for a secondary external amplifier.
