Figure 1-1. Model PA640.
•
The Federal Signal Model PA640 (figure 1-1) is a
precision built, efficient and economical full-featured
electronic siren and light control system. The siren
provides wail, yelp, and priority or high-low siren
tones as well as the horn ring transfer Tap II feature,
public address (PA), radio rebroadcast and an air
horn sound.
High degree of reliability is achieved
through the use of a crystal controlled
microprocessor, integrated circuits and
silicon output transistors.
•
Programmable rubberized pushbuttons
with inserts. Each pushbutton can be
programmed to be either: inactive,
momentary, push on/push off, 8 second
timer, simultaneous, or alternate
flasher. The flash rate is selectable,
either 75 or 120 flashes per minute.
Relay pushbuttons can be attached to
slide switch positions 1, 2, or 3.
•
The control panel is illuminated with
non-glare backlighting.
The unit may be installed in negative ground
vehicles with 12-volt electrical systems. The siren
circuits are protected against failure by user-supplied
fuses. The audio power amplifier contains circuitry
that protects the output transistor stages against
speaker and wiring short circuits. The relay outputs
are protected against failure by user-supplied fuses.
No components protrude from the bottom of the siren
to interfere with mounting arrangements.
•
Printed circuit boards using surface
mount technology provide improved
performance and durability under a
wide range of environmental conditions.
•
Park-Siren Deactivator can deactivate
siren tones when the vehicle is shifted
into PARK.
A noise-canceling microphone is provided. It
provides high quality voice reproduction without
feedback squeal. The microphone push-to-talk switch
overrides any siren sound for instant Public Address
use. PA volume is adjustable by means of a front
panel VOLUME control.
•
The wail and yelp siren tones comply
with SAE J1849 JUL2002 and CCR
Title 13 Class ‘A’ specifications.
•
Siren tones can be programmed to be
dependent or independent of the slide
switch.
The PA640 is designed to drive one 11-ohm
impedance, high power (100W) speaker.
•
The horn ring transfer feature allows the driver
to change the siren sound from wail to yelp to priority/high-low to wail… via the vehicle’s horn ring. This
feature provides especially effective traffic clearing
capability. Each slide switch position can be individually programmed for siren dependency, transfer of the
An electronic beeper chirps upon
function selection. The beeper is dip
switch selectable to chirp every 10
seconds if a function is active.
•
The siren tones can be selected by dip
switch to cut-out or coast down when
deactivated.
On-board relays in the unit allow centralized
control and wiring of primary, secondary, alley lights,
and auxiliary circuits with a lighted rubberized
membrane switch assembly. A convenient fourposition Mode slide switch allows simplified and
rapid selection of most common siren and lighting
functions and changes the horn ring function accordingly to provide the Tap II feature.

SAFETY MESSAGE TO OPERATORS OF FEDERAL SIGNAL ELECTRONIC SIRENS
AND LIGHT/SOUND SYSTEMS
Signaling Limitations
WARNING
The lives of people depend on your safe
operation of Federal 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:
•
Be aware that the use of your visual and
audible signaling devices does not give you
the right to force your way through traffic.
Your emergency lights, siren, and actions
are REQUESTING the right-of-way.
•
Although your warning system is operating
properly, it may not alert everyone. People
may not hear, see, or heed your warning
signal. You must recognize this fact and
continue driving cautiously.
•
Situations may occur which obstruct your
warning signal when natural or man-made
objects are between your vehicle and others.
This can also occur when you raise your
hood or trunk lid. If these situations occur,
be especially careful.
•
The LED indicators on the siren control
switches simulate the light pattern(s) being
executed by the warning system. The display
is intended ONLY as a guide and NOT as an
indication of proper warning system operation. Before using the warning system, its
operation should be observed from outside
the vehicle.
Qualifications
•
To properly use an electronic siren and
speaker(s): you must have a good understanding of general vehicle operation, a high
proficiency in the use of safety warning
equipment, and thorough knowledge of state
and federal UNIFORM TRAFFIC CODES.
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, roll up your windows
and wear hearing protection. Do not sound
the siren indoors or in enclosed areas where
you and others will be exposed to the sound.
Only use the siren for emergency response
situations.
Driving Limitations
•
At the start of your shift, you should ensure
that the light/sound system is securely
attached to the vehicle and operating
properly.
•
If the unique combination of emergency
vehicle equipment installed in your vehicle
has resulted in the siren controls being
installed in a position that does not allow
you to operate them by touch only, OPERATE CONTROLS ONLY WHILE YOUR
VEHICLE IS STOPPED.
•
If driving conditions require your full
attention, you should avoid operating the
siren controls while the vehicle is in motion.
Sound Limitations
•
•
•
Before using the vehicle, check to see if the
siren speakers are concealed from view. If
the siren speaker is not in clear view on the
front of the vehicle, use extra caution when
operating the vehicle. A concealed siren
speaker installation is less effective at
warning others.
Maximum sound output will be severely
reduced if any objects are in front of the
speaker. If your installation has obstructions
in front of the speaker, drive even more
cautiously.
Continuing Education
•
Frequently inspect the speaker to ensure
that it is clear of any obstruction, such as
mud or snow, which will reduce maximum
sound output.
File these instructions in a safe place and
refer to them periodically. Give a copy of
these instructions to new recruits and
trainees.
Failure to follow these safety precautions may
result in property damage, serious injury, or death to
you, to passengers, or to others.

SECTION IV
INSTALLATION
SAFETY MESSAGE TO INSTALLERS
OF
ELECTRONIC SIRENS
WARNING
The lives of people depend on your proper installation
and servicing of Federal 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:
•
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 air
bag sensors.
•
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.

SECTION V
OPERATION
SAFETY MESSAGE TO OPERATORS OF
FEDERAL SIGNAL ELECTRONIC SIRENS
AND LIGHT/SOUND SYSTEMS
•
WARNING
The lives of people depend on your safe
operation of Federal 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:
Signaling Limitations
•
Be aware that the use of your visual and
audible signaling devices does not give you
the right to force your way through traffic.
Your emergency lights, siren, and actions
are REQUESTING the right-of-way.
•
Although your warning system is operating
properly, it may not alert everyone. People
may not hear, see, or heed your warning
signal. You must recognize this fact and
continue driving cautiously.
•
Situations may occur which obstruct your
warning signal when natural or man-made
objects are between your vehicle and others.
This can also occur when you raise your
hood or trunk lid. If these situations occur,
be especially careful.
Qualifications
•
To properly use an electronic siren and
speaker(s): you must have a good understanding of general vehicle operation, a high
proficiency in the use of safety warning
equipment, and thorough knowledge of state
and federal UNIFORM TRAFFIC CODES.
Sound Hazards
•
•
Frequently inspect the speaker to ensure
that it is clear of any obstruction, such as
mud or snow, which will reduce maximum
sound output.
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.”
Driving Limitations
All effective sirens and horns produce loud
sounds (120 dB) that may cause permanent
hearing loss. Always minimize your exposure to siren sound, roll up your windows
and wear hearing protection. Do not sound
the siren indoors or in enclosed areas where
you and others will be exposed to the sound.
Only use the siren for emergency response
situations.
•
At the start of your shift, you should ensure
that the light/sound system is securely
attached to the vehicle and operating
properly.
•
If the unique combination of emergency
vehicle equipment installed in your vehicle
has resulted in the siren controls being
installed in a position that does not allow
you to operate them by touch only, OPERATE CONTROLS ONLY WHILE YOUR
VEHICLE IS STOPPED.
•
If driving conditions require your full
attention, you should avoid operating the
siren controls while the vehicle is in motion.
Sound Limitations
•
•
Before using the vehicle, check to see if the
siren speakers are concealed from view. If
the siren speaker is not in clear view on the
front of the vehicle, use extra caution when
operating the vehicle. A concealed siren
speaker installation is less effective at
warning others.
Continuing Education
•
Maximum sound output will be severely
reduced if any objects are in front of the
speaker. If your installation has obstructions
in front of the speaker, drive even more
cautiously.
File these instructions in a safe place and
refer to them periodically. Give a copy of
these instructions to new recruits and
trainees.
Failure to follow these safety precautions may
result in property damage, serious injury, or death to
you, to passengers, or to others.

Federal Signal siren amplifiers and
speakers are designed to work together
as a system. Combining a siren and

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 both federal, state and local
standards or guidelines.
Failure to follow all safety precautions and
instructions may result in property damage,
serious injury, or death to you or others.
Electronic circuit and speaker repairs
must be performed by a qualified and
competent electronic technician.
