extension cable kit, is also available.
The Model PA4000U is designed to drive one
100 watt speaker.
Other special features of the Model PA4000U
include:
Figure 1-1. Model PA4000U.
The Federal Model PA4000U (figure 1-1) is a
precision built, efficient and economical electronic
siren incorporating state-of -the-art design. It provides wail, Tap II, yelp and manual peak-and-hold.
The Tap II feature allows the driver to change the
siren sound from wail to yelp via the vehicle’s horn
ring. This can also be accomplished by depressing the
control head’s
Tap II switch. Tap II provides an especially effective
traffic clearing capability.
•
High degree of reliability is achieved
through the use of a CMOS microprocessor and silicon output transistors.
•
The printed circuit board assembly
provides improved performance and
durability under a wide range of
environmental conditions.
•
AUX/OUT can drive an external relay
for controlling other devices, such as
warning lights.
The siren may be installed in negative ground
vehicles with 12-volt electrical systems. It is protected against failure modes (including reversed
polarity) by a fuse that is replaceable without tools.
No components protrude from the bottom of the siren
to interfere with mounting arrangements.
•
AUX/IN input can activate wail when
the WAIL/STBY switch is in the STBY
position.
•
Park-Siren Deactivator can deactivate
siren tones when the vehicle is shifted
into PARK.
The siren is made up of an Amplifier and a
Control Head. The Amplifier is suitable for mounting
in a dry, adequately ventilated location, while the
Control Head is designed for mounting under the
dashboard. Communication between the two units is
via the supplied cable. (See Section III for additional
information.)
•
When the WAIL/STBY switch is in the
STBY position, the horn ring will
activate the vehicle horn.
•
The peak-and-hold tone is activated
when depressing the TAPII/TEST
switch with the WAIL/STBY switch in
the STBY position.
The siren also has provisions for public address

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.
•
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.
•
DO NOT install equipment or route wiring or cord in the
deployment path of an air bag.
•
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.
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 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.
•
Federal Signal siren amplifiers 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.

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.
•
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.
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.

5-2. SIREN.
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.
A.
Removal for Servicing.
To remove the electronic assembly, located
inside the Amplifier chassis, for servicing; proceed as
follows :
1. Remove the two Phillips head screws
on the amplifier’s side which secure the cover to the
Amplifier chassis.
DO NOT connect this system to the positive
terminal of the battery until servicing is complete, and you have verified that there are no
short circuits to ground.
2. Remove the cover by sliding it away
from the chassis.
In order for the electronic siren to function
properly, the ground connection must be made
to the NEGATIVE battery terminal.
B.
Removal of Circuit Board.
The Amplifier logic circuit board (top circuit
board) is secured to the chassis by four Phillips head
screws. Unplug the eleven-position connector and the
red and black power connectors before removing the
screws.
After repair, test the electronic siren and
speaker system to ensure that it is operating
properly.

C.
Replacement of Output Transistors.
CAUTION
Before reinstalling the repaired PA4000U,
make certain that the speaker is not defective.
Failure of one or both of the output transistors (Q106, Q109) is usually the result of a defective
speaker (short circuited voice coil). Rebroadcast of
the unsquelched radio or music for long periods will
also have a detrimental effect on the output transistors, and is therefore not recommended.
D.
Testing.
WARNING
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.
Federal recommends that both output
transistors be replaced should only one device prove
to be defective. This practice will insure long periods
of service between failures.
When installing new output transistors,
insure that the Sil-Pad insulators are installed
between the heat sink and transistors.
After servicing is complete, perform a test
of all functions to ensure siren is operating properly.
