CHAPTER 1
Safety Messages for Installers and Operators
For your safety, read and understand this manual thoroughly before installing, operating, and
servicing the Pathnder siren amplier/relay module. The safety messages presented in this chapter
and throughout the manual are reminders to exercise extreme care at all times. In addition, read and
understand the safety instructions to installers (doc. no. 256A692), and keep it close at hand for
reference.
To download copies of this manual, go to www.fedsig.com or call the Federal Signal Service
Department at 1-800-433-9132 (708-534-3400) 7 a.m. to 5 p.m., Monday through Friday (CT).
Safety Messages to Installers of Sound/Light Systems
People’s lives depend on your proper installation and servicing of Federal Signal products. It is
important to read and follow all instructions shipped with this product. In addition, listed below are
some other important safety instructions and precautions you should follow:
Before Installation
Qualications
• To properly install an electronic siren, you must have a good understanding of automotive
electrical procedures and systems, along with prociency in the installation and service of safety
warning equipment. Always refer to the vehicle’s service manuals when performing equipment
installations on a vehicle.
Sound Hazards
• Your hearing and the hearing of others, in or close to your emergency vehicle, could be damaged
by loud sounds. This can occur from short exposures to very loud sounds, or from longer
exposures to moderately loud sounds. For hearing conservation guidance, refer to federal, state,
or local recommendations. OSHA Standard 1910.95 offers guidance on “Permissible Noise
Exposure.”
• All effective sirens and horns produce loud sounds (120 dB) that may cause permanent hearing
loss. Always minimize your exposure to siren sound and wear hearing protection. Do not sound
the siren indoors or in enclosed areas where you and others will be exposed to the sound.

PathnderTM
Chapter 1: Safety Messages for Installers and Operators

• Federal Signal siren amplier/relay modules and speakers are designed to work together as a
system. Combining a siren and speaker from different manufacturers may reduce the warning
effectiveness of the siren system and may damage the components. You should verify or test your
combination to make sure the system works together properly and meets federal, state and local
standards or guidelines.
During Installation
• Do NOT get metal shavings inside the product. Metal shavings in the product can cause the
system to fail. If drilling must be done near the unit, place an ESD approved cover over the unit to
prevent metal shavings from entering the unit. Inspect the unit after mounting to be sure there are
no shavings present in or near the unit.
• Do NOT connect this system to the vehicle battery until ALL other electrical connections are
made, mounting of all components is complete, and you have veried that no shorts exist. If
wiring is shorted to vehicle frame, high current conductors can cause hazardous sparks resulting in
electrical res or ying molten metal.
• Be sure the siren amplier/relay module and speaker(s) in your installation have compatible
wattage ratings.
• In order for the electronic siren to function properly, the ground connection must be made to the
NEGATIVE battery terminal.
• Sound output will be severely reduced if any objects are in front of the speaker. If maximum
sound output is required for your application, you should ensure that the front of the speaker is
clear of any obstructions.
• Install the speaker(s) as far forward on the vehicle as possible, in a location which provides
maximum signaling effectiveness and minimizes the sound reaching the vehicle’s occupants.
Refer to the National Institute of Justice guide 500-00 for further information.
• Mounting the speakers behind the grille will reduce the sound output and warning effectiveness of
the siren system. Before mounting speakers behind the grille, make sure the vehicle operators are
trained and understand that this type of installation is less effective for warning others.
• Sound propagation and warning effectiveness will be severely reduced if the speaker is not facing
forward. Carefully follow the installation instructions and always install the speaker with the
projector facing forward.
• Do NOT install the speaker(s) or route the speaker wires where they may interfere with the
operation of airbag sensors.
• Installation of two speakers requires wiring speakers in phase.
• Never attempt to install aftermarket equipment, which connects to the vehicle wiring, without
reviewing a vehicle wiring diagram available from the vehicle manufacturer. Insure that your
installation will not affect vehicle operation and safety functions or circuits. Always check vehicle
for proper operation after installation.

Chapter 1: Safety Messages for Installers and Operators

PathnderTM
• Do NOT install equipment or route wiring or cord in the deployment path of an airbag.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to
be recalibrated for proper airbag deployment.
• Locate the control head so the vehicle, controls, and microphone can be operated safely.
• When drilling into a vehicle structure, be sure that both sides of the surface are clear of anything
that could be damaged. All drilled holes should be deburred and all sharp edges should be
smoothed. All wires going through drilled holes should be protected by a grommet or convolute/
split-loom tubing. Additionally, all exterior drilled holes must be sealed with Motorcraft seam
sealer T-A-2-B or equivalent to prevent the potential exposure to carbon monoxide or other
potentially harmful fumes. Failure to observe this warning could cause serious injury or death.
After Installation
• After installation, test the siren and light system to ensure that it is operating properly.
• Test all vehicle functions, including horn operation, vehicle safety functions and vehicle light
systems, to ensure proper operation. Ensure that installation has not affected vehicle operation or
changed any vehicle safety function or circuit.
• After testing is complete, provide a copy of these instructions to the instructional staff and all
operating personnel.
• File these instructions in a safe place and refer to them when maintaining or reinstalling the
product.
Failure to follow all safety precautions and instructions may result in property damage, serious injury,
or death.

Safety Messages to Operators of Sound/Light Systems
People’s lives depend on your safe operation of Federal Signal products. It is important to read and
follow all instructions shipped with the products. In addition, listed below are some other important
safety instructions and precautions you should follow:
• Do not attempt to activate or de-activate the light system control while driving in a hazardous
situation.
• Although your warning system is operating properly, it may not be completely effective. People
may not see or heed your warning signal. You must recognize this fact and continue driving
cautiously.
• Also, situations may occur which obstruct your warning signal when natural and man-made
objects are between your vehicle and others, such as raising your hood or trunk lid. If these
situations occur, be especially careful.
• All effective sirens and horns produce loud sounds that may cause, in certain situations, permanent
hearing loss. You and your passengers should consider taking appropriate safety precautions, such
as wearing hearing protection.
• In order to be an effective warning device, this product produces bright light that can be hazardous
to your eyesight when viewed at a close range. Do not stare directly into this lighting product at a
close range or permanent damage to your eyesight may occur.
• It is important that you fully understand how to safely operate this warning system before use.
• You should only operate your vehicle and its light/sound system in accordance with your
department’s Standard Operating Procedures.
• If a selected function does not perform properly or if any of the lamps remain illuminated when
the control is off, disconnect the power connector from the control unit and contact the nearest
service center.
• At the start of your shift, you should ensure that the entire warning light system and the siren
system is securely attached and operating properly.
• The effectiveness of an interior mounted warning light depends on the clarity, the tinting, and the
angle of the glass it is being placed behind. Tinting, dirt, defects, and steeply angled glass reduce
the light output of the warning light. This may reduce the effectiveness of the light as a warning
signal. If your vehicle has dirty, tinted, or steeply angled glass, use extra caution when driving
your vehicle or blocking the right of way with your vehicle.
• Suction cup mounting is for temporary applications only. The unit should be removed from the
window and stored securely when not in use. Temperature changes and sunlight can cause suction
cups to lose holding power. Periodically check the unit to be sure the suction cups have a rm grip
on the mounting surface. An improperly secured light could fall off of the vehicle causing injury
and damage.

• The holding power of magnetic mounting systems is dependent upon surface nish, surface
atness, and thickness of the steel mounting surface.
Therefore, to promote proper magnetic mounting:
✓ The mounting surface and magnets must be kept clean, dry, and free of foreign particles that
prevent good surface contact.
✓ Ensure that the mounting surface is at.
✓ A magnet mounting system should not be used on vehicles with vinyl tops.
✓ To prevent the light assembly from sliding on mounting surface, avoid quick acceleration and
hard stops.
Failure to follow these precautions may result in property damage, serious injury, or death.

CHAPTER 2
An Overview of the Pathnder
The Pathnder 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 Pathnder siren
uses class D amplier 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 Conguration Software from a computer via a
USB cable that connects the siren amplier. System features include ash 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 Pathnder 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 Pathnder 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 Pathnder
to provide dual siren tones. Alternatively, the Pathnder 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 amplier.
Lightbars and SignalMasterTM Control
Compatible lightbars include full featured, serially-controlled Federal Signal Legend®, Valor®,
AllegiantTM, Navigator®, and Integrity®as well as the SpectraLux ILS Series of interior-mounted
lightbars. In addition, ash rates and patterns, lightbar dimming, external SignalMaster control and
other options can be programmed with the Convergence Network Conguration Software.

Chapter 2: An Overview of the Pathnder
PathnderTM 11
FS Vehicle Integration
The Pathnder siren includes the capability to integrate with the existing vehicle CAN bus. The
FS Vehicle Integration uses a vehicle specic cable (not included) to seamlessly integrate with the
vehicle. Vehicle events can be programmed with the Convergence Network Conguration Software to
interface with the lighting/siren control. The Convergence Network Conguration Software contains
the latest list of events supported based on model, make and year of the vehicle.
Programmable Solid-State Auxiliary Relays
The Pathnder has 12 solid-state relays: ve 10A active high solid-state relays: one 10 A high-low and
six 5 A high. The maximum output current for each relay can be set with the Convergence Network
Conguration Software.
Programmable Input Circuits
The Pathnder has connections for four general purpose input circuits, plus dedicated inputs for
park, horn and ign. Ignition is an active-high only input, while all other inputs are programmable for
active-high or active-low. The inputs are most commonly used for switches that send a signal to the
siren when a condition in the vehicle changes.
LED Indicators and Visual Diagnostics
All buttons on the control head glow when the system is on. Pressed buttons turn bright to indicate
that the function they control is active. The buttons are programmable for red or blue backlighting.
LEDs on the keypad mimic these active SignalMaster patterns: Left, Right, Center-Out, and Warn
patterns. An LED glows over the position in which the slide switch is placed. Diagnostic LEDs for
speaker fault detection are also available and are programmable.

CHAPTER 3
Wiring the Pathnder
General Guidelines for Wiring the Pathnder on a Vehicle
HIGH CURRENT ARCING: Do not connect this system to the vehicle battery until
ALL other electrical connections are made and you have veried that no shorts
exist. High current conductors can cause hazardous sparks or burning wire
resulting in electrical res.
DRILLING PRECAUTIONS: When drilling into a vehicle structure, be sure that
both sides of the surface are clear of anything that could be damaged. All drilled
holes should be deburred and all sharp edges should be smoothed. All wires
going through drilled holes should be protected by a grommet or convolute/
split-loom tubing. Additionally, all exterior drilled holes must be sealed with
Motorcraft seam sealer T-A-2-B or equivalent to prevent the potential exposure
to carbon monoxide or other potentially harmful fumes. Failure to observe this
warning could cause serious injury or death.
Before permanently installing the Pathnder system, plan all wire routings and select the mounting
locations for the siren amplier/relay module. Read and understand all instructions included with
related equipment before installing it. Ensure that all wiring is protected from damage during normal
operation of the vehicle and away from any sharp edges and screws. Splice joints should be soldered
or crimped with butt-connectors, and properly insulated. Splice joints that will be exposed to the
elements should be adequately sealed and insulated. All wires that are extended should not be a lesser
gauge than its original mating wire. Make sure that connections are easily accessible for assembly
and service.

Overview of the Pathnder Connections
To prepare the vehicle for connecting the Convergence Network system:
1. After planning where to route the wires and cables for the system components — such as Federal
Signal warning lights, directional lights, and speakers — drill the holes for the wiring. Smooth,
deburr, and insert a grommet in the holes.
2. Mount the system components according to the instructions included with each product.
The next sections describe how to connect and wire each system component to the siren amplier/
relay module.
Convergence Network Ports
There are two “plug and play” serial ports that communicate on the Federal Signal Convergence
Network. Federal Signal Network devices include exterior mount lightbar, interior mount
ILS systems and remote keypads. For instructions on mounting network devices, refer to
the instructions included with the products. For instructions on conguring the operation
of the devices connected through the Convergence Network ports, see the help menu in the
Convergence Network Conguration Software.
Relay Outputs
The Pathnder has a total of twelve solid-state relay output available. Relays 1-6 can each
provide up to 10 A switched from the battery terminal on the Pathnder. Relay 6 can switch
both battery (active-high) and ground (active-low). Relays 7-12 can each provide up to 5A
switched from the battery terminal on the Pathnder. Each relay has a software programmable
current limit set that can be set. By default, the current limit setting is disabled. Each relay also
can also be programmed to ash various patterns and dim levels. See the Convergence Network
Conguration Software for all available programming options available for the Pathnder
relay outputs.
General Purpose Inputs
The Pathnder has a total of four general purpose inputs available. These inputs are by default
set to detect active-high (battery). Each input can individually be programmed to detect an
active-high (battery) or active-low (ground). All inputs are software-congurable options
include siren activation or siren mute, timer settings, and switch operation. See the Convergence
Network Conguration Software for all available programming options available for the
Pathnder inputs.
Park Input
The park input circuit sends a signal to the siren amplier/relay module to mute all siren
functions except Air Horn and Manual and shut off any ashing white light in the lightbar when
the vehicle transmission is shifted into park. This input is by default set to detect active-low
(ground). The park input can be programmed to detect an active-high (battery) or active-low
(ground). The functionality of the park wire (as well as the input polarity) can be congured
with the Convergence Network Conguration Software. If using FS Vehicle Integration to detect
the park event, this wire is not used. Fold and seal.

siren can switch a maximum of 5 A. Some vehicles do not have a horn relay
and consequently will draw more than 5 A when the vehicle horn is activated.
Consult your vehicle service manual or a qualied mechanic to determine the
current required to activate the horn. If it is less than 5 A, perform step 3. If it is
greater than 5 A, perform steps 4 through 9.
The horn input circuit is designed to allow siren and lighting control from the vehicle horn.
This input is by default set to detect active-low (ground). The horn input can be programmed to
detect an active-high (battery) or active-low (ground). The horn signal event may be available
using FS Vehicle Integration, if so fold and seal the unused leads.
NOTE: To enable horn-ring control of siren tones, obtain a SPST relay of enough contact-
current capacity to activate the vehicle horn:
1. Cut the wire that connects the switch for the vehicle horn ring to the horn or horn relay
(Figure 3.3).
2. Splice the white/yellow wire from the power cable to the horn ring side of the wire
that you cut in step 1.
3. Splice the white wire from the power cable to the horn side of the cut wire.
4. Mount the SPST relay in a suitable location.
5. Connect the horn side of the wire cut in step 1 to the relay-contact terminal.
6. Determine the “sense” of the vehicle’s horn ring activation circuit. Does the horn
circuit require a switched positive (active-low) voltage or switched ground (active-high)
for activation?
7. Connect the switched relay-contact terminal to the positive or negative potential you
determined in step 6.
8. Connect the white wire from the power cable to one end of the relay coil.
9. Connect the other end of the relay coil to the opposite potential of that connected to
the switched relay contact terminal in step 7.
Speaker Connections
The Pathnder is designed to operate with a few different speaker congurations. It can operate
one or two 11-ohm impedance, 100 W speakers. If using two 11-ohm impedance, 100 W
speakers, they must be wired on separate channels of the amplier and in phase for proper
operation (see Figure 3.1). Alternatively, it can operate one 11-ohm impedance, 100 W speaker
and two Rumbler speakers, without the need for a separate amplier (see Figure 3.2). By
default, the siren is set for two 11-ohm impedance, 100 W speakers. See the Convergence
Network Conguration Software for all available programming options available for the
Pathnder tones.

Speaker Diagnostics
The Pathnder siren is designed to detect speaker faults. Diagnostic LEDs available on the
front of the keypad that can provide operating status of each of the amplier outputs. The LEDs
are fully programmable and can be set to steady burn or ash when the siren detects a fault or
normal operation for each individual speaker. By default, the diagnostic LEDs are disabled, but
can be programmed with the Convergence Network Conguration Software.
Radio Re-Broadcast
The Radio Re-Broadcast inputs allow incoming two-way radio messages to be amplied by the
siren amplier/relay module and rebroadcast over the siren speakers. The Radio Re-Broadcast
gain is set in the Convergence Network Conguration Software.
FS Vehicle Integration
The Pathnder can interface with the vehicle’s OBDII port or up-tter CAN bus, using a
separately available cable harness. Common signals that can be obtained are transmission,
door, headlight, brake and speed statues. Many other signals may available depending on
the make and model of vehicle. See the Convergence Network Conguration Software for
programming options. If using FS Vehicle Integration, discrete wiring inputs may not be
required for park, horn ring and/or ignition. By default, the PathFinder has the FS Vehicle
Integration port disabled.
Ignition Input
The ignition input a programmable active high input that can be used to turn on and off the
Pathnder system. This input can be programmed to keep the system alive for a set time
after ignition is removed. This input is by default set to turn off the system immediately
when ignition is removed. The functionality of the ignition wire can be congured with the
Convergence Network Conguration Software. If using FS Vehicle Integration to detect the
ignition event or key position, this wire is not used. Fold and seal.
System Power
The Pathnder system includes ring terminals for connecting the battery. The installer-supplied
red (positive) and black (negative ground) power leads from the siren to the vehicle battery
should be as short and direct as possible. Crimp the supplied ring terminal on the red lead
and connect it through an in-line fuse to the positive battery terminal. The fuse must be of an
amperage capacity sufcient to handle the total vehicle electrical loads plus siren. Crimp the
supplied ring terminal on the black lead and connect it to the negative battery terminal. See
Figure 3.3 for proper ring terminal orientation.
