Introduction
The 3930 series siren is a new series of electronic sirens that has been designed to meet the needs of all
emergency vehicles. This series of sirens incorporates a rugged extruded aluminum package along with
microprocessor based circuitry and MOSFET technology. Advanced features such as Park Kill, Instant
"ON", Adjustable Backlighting, "Horn Ring Scroll" and more, make the 3930 series sirens extremely
versatile.
Sirens are an integral part of an effective audio/visual emergency warning system.
However, sirens are only short range secondary warning devices. The use of a siren
does not insure that all drivers can or will observe or react to an emergency warning
WARNING!
signal, particularly at long distances or when either vehicle is traveling at a high rate of
speed. Sirens should only be used in a combination with effective warning lights and
never relied upon as a sole warning signal. Never take the right of way for granted. It is
your responsibility to be sure you can proceed safely before entering an intersection,
driving against traffic, or responding at a high rate of speed.
The effectiveness of this warning device is highly dependent upon correct mounting and
wiring. Read and follow the manufacturer’s instructions before installing or using this
device. The vehicle operator should check the equipment daily to insure that all features
of the device operate correctly.
To be effective, sirens must produce high sound levels that potentially can inflict hearing
damage. Installers should be warned to wear hearing protection, clear bystanders from
the area and not to operate the siren indoors during testing. Vehicle operators and
occupants should assess their exposure to siren noise and determine what steps, such
as consultation with professionals or use of hearing protection should be implemented to
protect their hearing.
This equipment is intended for use by authorized personnel only. It is the user’s responsibility to understand and obey all laws regarding emergency warning devices. The user
should check all applicable city, state and federal laws and regulations.
Public Safety Equipment, Inc., assumes no liability for any loss resulting from the use of
this warning device.
Proper installation is vital to the performance of the siren and the safe operation of the
emergency vehicle. It is important to recognize that the operator of the emergency
vehicle is under psychological and physiological stress caused by the emergency
situation. The siren system should be installed in such a manner as to: A) Not reduce the
acoustical performance of the system, B) Limit as much as practical the noise level in the
passenger compartment of the vehicle, C) Place the controls within convenient reach of
the operator so that he can operate the system without losing eye contact with the
roadway.
Emergency warning devices often require high electrical voltages and/or currents.
Properly protect and use caution around live electrical connections. Grounding or
shorting of electrical connections can cause high current arcing, which can cause
personal injury and/or severe vehicle damage, including fire.
PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE
OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF
EMERGENCY PERSONNEL AND THE PUBLIC.
Standard Features
The 3930 series sirens consist of integrated controls and amplifier in a single package. The siren is available
in two models as follows:
The following features are standard on Model 3930 sirens:
Siren Tones - Industry standard Wail, Yelp, and HyperYelp tones.
AIR HORN Tone - Electronic AIR HORN sound.
2
Instant-On- There is no " ON/OFF " switch. Selecting any siren function, or keying the microphone will
!
activate the siren assuming the siren is connected to a source of +12V.
Automatic Short Circuit Protection- The siren will sense a short circuit on the speaker terminals and
automatically go to standby until the fault is removed. Once the fault is removed the siren will return to normal
operation.
Instant Public Address - Public Address override of all siren functions when the microphone Push-to-Talk
(PTT) key is pressed.
Noise Cancelling Microphone - Wired in microphone that is easily unplugged internally for service or
replacement.
In addition to the standard features of the Model 3930 siren listed above, the following features are standard
on Model 3932 sirens:
Radio Rebroadcast - Broadcasts Two-way radio reception over siren speakers. These inputs are
transformer coupled to prevent loading of the radio.
Park Kill- This feature deactivates the siren tones when the vehicle is shifted into park. Once PKILL is
activated the siren will remain deactivated until the vehicle is shifted into gear and the siren is restarted using
the Horn Ring Scroll feature or the front panel switches.
Adjustable Backlighting- Backlighting is independent of siren power. Allows connecting to dimmer if
desired.
Horn Ring (Remote) Scroll - The siren accepts either a positive or a ground (Earth) signal, usually from the
vehicle's horn switch (or other user supplied switch), and remotely scrolls through the siren tones or activates
AIR HORN function. See Set-up and Adjustments section for details.
®
InterClear
the siren mode is changed using either the control switches or the vehicle horn ring, thus allowing an
additional level of warning in situations such as intersections without the operator having to take his hands off
the wheel or his eyes off the road.
- This unique feature can be used to activate additional warning lights for 7 seconds, each time
Unpacking & Pre-installation
After unpacking your 3930 series siren, carefully inspect the unit and associated parts for any damage that
may have been caused in transit. Report any damage to the carrier immediately.
Installation & Mounting
The 3930 series siren may be mounted above the dash, below the dash, on a tunnel or in a rack with the
mounting bracket (bail) and the hardware supplied (see Fig. 1). Ease of operation and convenience to the
operator should be the prime consideration when mounting the siren and controls.
All devices should be mounted in accordance with the manufacturer’s instructions and
securely fastened to vehicle elements of sufficient strength to withstand the forces applied
to the device. Ease of operation and convenience to the operator should be the prime
consideration when mounting the siren and controls. Adjust the mounting angle to allow
maximum operator visibility. Do not mount the Control Head Module in a location that will
WARNING!
obstruct the drivers view. Mount the microphone clip in a convenient location to allow the
operator easy access. Devices should be mounted only in locations that conform to their
SAE identification code as described in SAE Standard J1849. For example, electronics
designed for interior mounting should not be placed underhood, etc.
Controls should be placed within convenient reach* of the driver or if intended for two
person operation the driver and/or passenger. In some vehicles, multiple control switches
and/or using methods such as “horn ring transfer” which utilizes the vehicle horn switch to
toggle between siren tones may be necessary for convenient operation from two positions.
*Convenient reach is defined as the ability of the operator of the siren systems to manipulate
the controls from his normal driving/riding position without excessive movement away from
the seat back or loss of eye contact with the roadway.

The bail is mounted to the siren chassis by means of the "T" slot in
the side of the unit and the 1/4-20 hex head bolts, washers, and
nuts supplied. See Figure 1 for assembly and positioning details.
Note that once the unit is installed, removal involves only
loosening, not removing, the acorn nuts.
NOTE: Set-ups and adjustments will be made in subsequent steps,
depending upon the model and options purchased, that may
require access to the rear area of the unit. Plan the installation and
wiring accordingly.
Larger wires and tight connections will provide longer service life for components. For high
current wires it is highly recommended that terminal blocks or soldered connections be used
with shrink tubing to protect the connections. Do not use insulation displacement connectors
WARNING!
(e.g. 3M® ) Scotchlock type connectors). Route wiring using grommets and sealant when
passing through compartment walls. Minimize the number of splices to reduce voltage drop.
High ambient temperatures (e.g. underhood) will significantly reduce the current carrying
capacity of wires, fuses, and circuit breakers. Use "SXL" type wire in engine compartment.
All wiring should conform to the minimum wire size and other recommendations of the
manufacturer and be protected from moving parts and hot surfaces. Looms, grommets, cable
ties, and similar installation hardware should be used to anchor and protect all wiring.
Fuses or circuit breakers should be located as close to the power takeoff points as possible
and properly sized to protect the wiring and devices. Particular attention should be paid to the
location and method of making electrical connections and splices to protect these points
from corrosion and loss of conductivity. Ground (Earth) terminations should only be made
to substantial chassis components, preferably directly to the vehicle battery.
The user should install a circuit breaker sized to approximately 125% of the maximum Amp
capacity in the supply line to protect against short circuits. For example, a 30 Amp circuit
breaker should carry a maximum of 24 Amps.
DO NOT USE 1/4" DIAMETER GLASS FUSES AS THEY ARE NOT SUITABLE FOR
CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit breakers are very sensitive to
high temperatures and will "false trip" when mounted in hot environments or operated close
to their capacity.

Connections (see Figure 2)
ORANGE - Speaker - Connect to 100W ( 11 ohm ) speaker leads.
CONNECTION OF A 58 WATT SPEAKER TO THE SPKR TERMINAL WILL CAUSE THE
SPEAKER TO BURN OUT, AND WILL VOID THE SPEAKER WARRANTY!
The sound projecting opening should be pointed forward, parallel to the ground, and not
WARNING!
obstructed or muffled by structural components of the vehicle. Concealed or under-hood
mountings in some cases will result in a dramatic reduction in performance. To minimize this
reduction, mount the speaker so the sound emitted is projected directly forward and
obstruction by vehicle components such as hoses, brackets, grille, etc. is minimized.
Electromechanical sirens and electronic siren speakers should be mounted as far from the
occupants as possible using acoustically insulated compartments and isolation mountings to
minimize the transmission of sound into the vehicle. It may be helpful to mount the device on
the front bumper, engine cowl or fender; heavily insulate the passenger compartment; and
operate the siren only with the windows closed.
Each of these approaches may cause significant operational problems, including loss of siren
performance from road slush, increased likelihood of damage to the siren in minor collisions,
and the inability to hear the sirens on other emergency vehicles.
APPROPRIATE TRAINING OF VEHICLE OPERATORS IS RECOMMENDED TO ALERT
THEM TO THESE PROBLEMS AND MINIMIZE THE EFFECT OF THESE PROBLEMS
DURING OPERATIONS.

Any electronic device may create or be affected by electromagnetic interference. After
installation of any electronic device, operate all equipment simultaneously to insure
that operation is free of interference.
WARNING!
WARNING!
The only adjustments necessary for the 3930 series sirens are Maximum P.A. Adjustment (accessible from
the front of the unit), and Maximum RRB Adjustment (accessible from the rear of the unit). Refer to Figure
3 for the location of these adjustments. The Horn Ring (Remote) input polarity is configured at the factory to
respond to a GND (Earth) signal. Refer to the procedure described under Horn Ring (Remote) Input
Configuration if your application requires that this input respond to a positive signal. Make these adjustments
prior to placing the unit inside the bail bracket.
Audio Adjustments
Maximum Radio Rebroadcast (RRB)
Adjustment - This trimmer (located on the rear
of the siren) sets the maximum level that the 2way radio will reach with the front panel
VOLUME control in the fully clockwise position.
To adjust properly, set the 2-way radio volume
control to produce normal radio volume inside
the vehicle. Slide the RRB switch to the right to
enable the RRB function. Next set the siren's
front panel VOLUME control knob fully clockwise
and adjust the rear panel RRB trimmer to
produce the desired volume outside the vehicle.

Rear View
Maximum P.A. Volume Adjustment - This
trimmer ( located on the front panel next to the
volume control knob ) sets the maximum level
that the P.A. volume will reach with the front
panel VOLUME control in the fully clockwise
position. To adjust properly, set the front panel
volume control fully clockwise. While keying the
microphone hold the microphone close to your
lips and speak directly into it in a normal voice
and adjust the trimmer until the maximum
volume out of the speaker is intelligible and
produces no feedback.

Operation (refer to Figure 5)
!
SCROLL v / MANUAL Momentary, Push-button Switch -This switch provides two distinctly different
functions depending on the mode of the siren when the switch is pressed and how long the operator holds the
switch. In order to fully understand the function of this switch read the following description carefully.
Tapping the MANUAL button will cause the siren to scroll down one mode. When the MANUAL button is
pressed and held, the siren will produce the MANUAL tone. Under this condition, when the button is released
the siren tone will ramp down to it's lowest frequency and the siren will revert to it's previous mode. Also refer
to the description of the "INSTANT-OFF" function.
SCROLL ^ Momentary, Push-button Switch - Each time the SCROLL ^ button is pressed it causes the
siren to scroll up one tone. Starting from the OFF mode, pressing the SCROLL ^ button will cause the siren
to start producing the WAIL tone. Pressing the button again will cause the siren to switch to YELP mode.
Pressing the button again will cause the siren to switch to HyperYelp mode. Pressing the button a fourth time
will cause the siren to switch back to WAIL
mode. This process may be repeated as often
as desired.
AIR HORN Momentary, Push-button Switch -
Produces the Air Horn tone. If the siren is active in
any mode except Manual mode, it reverts to that
previous mode when the AIR HORN button is
released. If the siren is active in MANUAL mode
when the AIR HORN button is pushed, it reverts to
OFF when the AIR HORN button is released.
Figure 5 - Control
IMPORTANT WARNINGS TO USERS OF SIRENS: "Wail" and "Yelp" tones are in some
cases (such as in the state of California) the only recognized siren tones for calling for
the right of way. Ancillary tones such as "Air Horn", "Hi-Lo", "Hyperyelp", and
WARNING!
INSTANT OFF - The siren may be turned off from any mode by simultaneously pressing the SCROLL ^
arrow button and the SCROLL v arrow button. Also refer to the description of the PARK KILL feature.

is used to enable (right position) or disable (left position) the Radio Rebroadcast (RRB) function.
is enabled, all other siren functions except PA are disabled.
When the switch is to the right, the 2-way radio audio connected to the RRB input wires is routed through the
siren amplifier to the siren speaker. The audio level at the speaker is set by adjusting the front panel volume
control knob. Also refer to Maximum Radio Rebroadcast (RRB) Adjustment.
PUBLIC ADDRESS (PA) - The PA portion of the siren is activated each time the microphone PTT button is
pressed. While the PTT button is pressed, the PA function over-rides any active siren tone and routes the
PA audio through the siren speaker. When the PTT button is released, the siren will automatically switch
back to the siren tone (if any) that was active when the button was pressed.
"Hyperlo" in some cases do not provide as high a sound pressure level. It is
recommended that these tones be used in a secondary mode to alert motorists to the
presence of multiple emergency vehicles or to momentarily shift from the primary tone
as an indication of the imminent presence of an emergency vehicle.
