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. Listed below are some other important safety instructions and precautions
you should follow:
Before Installation
Qualifications
• To properly install an electronic siren, you must have a good understanding
of automotive electrical procedures and systems, along with proficiency 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 oers guidance on “Permissible Noise Exposure.”
• All eective 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.
• Federal Signal siren amplifier/relay modules and speakers are designed to
work together as a system. Combining a siren and speaker from dierent
manufacturers may reduce the warning eectiveness of the siren system and
may damage the components. 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 ensure that 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
verified that no shorts exist. If wiring is shorted to vehicle frame, high current
conductors can cause hazardous sparks, resulting in electrical fires or flying
molten metal.
• Ensure that the siren amplifier/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, 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 that
provides maximum signaling eectiveness 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 eectiveness 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 eective for warning others.
• Sound propagation and warning eectiveness 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.
• Never attempt to install aftermarket equipment, which connects to the vehicle
wiring, without reviewing a vehicle wiring diagram available from the vehicle
manufacturer. Ensure that your installation will not aect vehicle operation and
safety functions or circuits. Always check vehicle for proper operation after
installation.
• 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.

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. Listed
below are some other important safety instructions and precautions you should
follow:
• Do not attempt to activate or deactivate the light system control while driving in
a hazardous situation.
• Although your warning system is operating properly, it may not be completely
eective. People may not see or heed your warning signal. You must recognize
this fact and continue to drive cautiously.
• Situations may occur that 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 eective 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 eective 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.
• 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 o, disconnect the power connector from the
control unit and contact the nearest service center.
• At the start of your shift, ensure that the entire warning light system and the
siren system is securely attached and operating properly.
• The eectiveness 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 eectiveness 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 firm grip on the

OverviewThe Pathway 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 (Self -Contained), in the trunk, or under the seat (remote) of any vehicle
with a 12 V or 24 V negative ground system. The Pathway siren uses class D
amplifier technology without the need for a large and heavy transformer. The
PW100 provides one 100-watt channel.
The module provides the automatic, simultaneous light and siren activation
required by some jurisdictions. 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. A variety of system features
can be programmed with the Convergence Network Configuration Software
(downloadable at www.fedsig.com/software-downloads) from a computer via a USB
cable that connects the siren amplifier. System features include flash patterns, siren
tones, momentary, push-on/push-o, and timed relay operation. The provided gun
lock timer feature may be configured to be dependant on other features (additional
button press, press-and-hold, etc.) to reduce the possibility of unauthorized access.
Siren, PA, and Speakers
The Pathway produces wail, yelp, priority, HI-LO, and 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 PW100 Pathway can drive one 11-ohm impedance, 100-watt speaker on one
channel.

General Guidelines for Wiring the Pathway 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: Before drilling holes, check the area into which
you plan to drill to ensure that you do not damage vehicle components. All
drilled holes should be deburred, and all sharp edges should be smoothed.
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 Pathway system, plan all wire routings and select
the mounting locations for the siren amplifier/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 their original mating wire. Make sure that
connections are easily accessible for assembly and service.

Overview of the Pathway 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 amplifier/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
light bar, interior mount ILS systems, and remote keypads. For instructions on
mounting network devices, refer to the instructions included with the products.
For instructions on configuring the operation of the devices connected through
the Convergence Network ports, see the Help menu in the Convergence Network
Configuration Software.
Relay Outputs
The Pathway®has a total of twelve solid-state relay outputs available. Relays 1-8
can each provide up to 5 A switched from the battery terminal on the Pathway.
Relays 9-12 can each provide up to 20 mA maximum switched to ground trigger
output to another device. Relays 1-8 have a software programmable current limit
that can be set. By default, the current limit setting is disabled. Each relay can also
be programmed to flash various patterns and dim levels. See the Convergence
Network Configuration Software for all available programming options available for
the Pathway relay outputs.
General Purpose Inputs
The Pathway has a total of four general-purpose inputs available. These inputs
detect active-high (battery). All inputs are software-configurable options that
include siren activation or siren mute, timer settings, and switch operation. See
the Convergence Network Configuration Software for all available programming
options available for the Pathway inputs.
Park Input
The park input circuit sends a signal to the siren amplifier/relay module to mute all
siren functions except Air Horn and Manual and shut o any flashing white light in
the light bar when the vehicle transmission is shifted into park. By default, this input
is 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 configured with the Convergence Network
Configuration Software.

Federal Signal www.fedsig.com
Horn Ring Transfer
DETERMINE CURRENT FOR HORN: The horn ring transfer circuit of the
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 steps 1 through 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 set to detect active-low (ground) by default. The horn
input can be programmed to detect an active-high (battery) or active-low (ground).
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. See Figure 2.
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-high) voltage or switched ground
(active-low) 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.

The Pathway PW100 is designed to operate with one 11-ohm impedence, 100W
speaker.
Speaker Diagnostics
The Pathway siren is designed to detect speaker faults. Diagnostic LEDs available
on the front of the keypad can provide operating status of the amplifier output. The
LED is fully programmable and can be set to steady burn or flash when the siren
detects a fault or normal operation for the speaker. By default, the diagnostic LEDs
are disabled but can be programmed with the Convergence Network Configuration
Software.

Radio Re-Broadcast
The Radio Re-Broadcast inputs allow incoming two-way radio messages to be
amplified by the siren amplifier/relay module and rebroadcast over the siren
speakers. The Radio Re-Broadcast gain is set in the Convergence Network
Configuration Software.
Ignition Input
The ignition input is a programmable active high input that can be used to turn on
and o the Pathway system. This input can be programmed to keep the system
alive for a set time after ignition is removed. By default, this input is set to turn o
the system immediately when ignition is removed. The functionality of the ignition
wire can be configured with the Convergence Network Configuration Software.
System Power
The Pathway®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 su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 2 for
proper ring terminal orientation.

Mounting the Pathway
The next step in the installation after wiring and connecting the system is to
permanently mount the siren in the vehicle. Verify that the mounting locations you
selected earlier are safe for installing these components. Review the following
precautions before mounting the equipment.
AIRBAG DEPLOYMENT: Do not install equipment or route wiring in the
deployment path of an airbag. Failure to observe this warning will reduce
the eectiveness of the airbag or potentially dislodge the equipment,
causing serious injury or death.
SEAT REMOVAL PRECAUTION: If a vehicle seat is temporarily removed,
verify with the vehicle manufacturer if the seat needs to be recalibrated for
proper airbag deployment.
UNIT REQUIRES AIR FLOW: Do not install the siren in areas where the air
ow is restricted. Do not mount the unit near a heater duct or under the
hood.
MODULE IS NOT WATERPROOF: The housing of the siren is NOT waterproof.
Select a mounting location that allows the vehicle, controls, and microphone to
be operated safely under all driving conditions. To identify safe mounting areas
for equipment inside the vehicle, consult the vehicle manufacturer’s guidelines.
To avoid driver distraction and unreliable switch activation, the mounting location
must not allow any movement of the unit. Installer-supplied mounting hardware is
required to mount the siren.
