Introduction
The 3992 series sirens are remotely controlled electronic sirens that has been designed to meet the needs of
all emergency vehicles. This series of sirens incorporates the popular features of the existing siren with
microprocessor based circuitry and MOSFET technology. All of the original
along with many added CODE 3 features such as; Park Kill, Instant "ON", Adj. " Scroll " Mode and more.
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
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.

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.
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.

Standard Features
The 3992 series sirens consist of a remotely mounted siren amplifier with an optional second amplifier,
providing up to 400W of siren power and opposing siren tones when both amplifiers are installed. The siren
system is operated by a compact control panel designed to be conveniently mounted near the operator. The
models are as follows:
3992 - Primary Tones: Wail, Yelp, Hi-Lo, Air Horn
- Secondary Tones: HyperYelp, HyperLo
3992XAMP - Primary Tones: Wail, Yelp, Hi-Lo, Air Horn
- Secondary Tones: HyperYelp, HyperLo

It is important to note that the 3992XAMP is
compatible with the popular RLS series sirens and
may also be used as a 2nd amplifier with these
sirens.
The following features are standard in the 3992 series
sirens (tones and sequences may differ with model and
options):
Instant-On- There is no " ON/OFF " switch. Selecting
any
siren function, or keying the microphone will activate the
selected siren function, assuming the siren is properly installed and the vehicle's ignition is switched on.
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 drive and an
action occurs such as depressing one of the siren control switches or keying the microphone. Any of these
actions will cause the siren tones to start again.
Adjustable Backlighting- Backlighting is independent of siren power. Allows connecting to dimmer if desired.
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.
Scroll Mode- Setting the slide switch on the rear of the siren to the SCROLL position will put siren in scroll
mode. This will allow "scrolling" through tones utilizing sharp taps on the horn ring, or a switch, via the Remote
siren input. In this mode holding the horn ring for prolonged durations will produce the Air Horn sound. See
OPERATION section for further details.
Hit-n-Go Mode - Setting the slide switch on the rear of the siren to the Hit-N-Go position will put the siren in the
Hit-n-Go mode. This mode will be most familiar to existing users. A seven second override is
standard for all tones when activated by the Remote input. See OPERATION section for details.
Figure 1 - Control Panel
Automatic Siren Tones - Industry standard Wail, Yelp, and Hi-Lo tones.
AIR HORN Tone - Electronic AIR HORN sound.
Instant Public Address - Public Address override of all siren functions when the microphone Push-to-Talk key
is pressed.
Status LED - An indicator LED, visible on the front of the remote siren amplifier indicates that the unit is on
when lighted.
Radio Rebroadcast - Broadcast Two-way radio reception over siren speakers. These inputs are transformer
coupled to prevent loading of the radio.
Remote Siren Switching - The siren accepts either a positive or a ground (earth) signal, usually from the
vehicle's horn switch (or other user supplied switch), to remotely activate the MANUAL or AIR HORN functions.
(MANUAL or AIR HORN is selected via the slide switch located on the front panel of the siren amplifier. The
siren is factory set for a GND (Earth) signal and may be reconfigured to accept a positive signal. See
SETUP and Adjustments and Operation sections for details.
Noise Cancelling Microphone - Plug-in microphone that is easily unplugged for service or replacement.

Unpacking & Pre-installation
After unpacking your 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 3992 series siren control may be mounted above the dash, below the dash, on a tunnel or in a rack with
the mounting hardware supplied (see Fig. 1). Ease of operation and convenience to the operator should be
the prime consideration when mounting the siren and controls
.
NOTE: Setups and
adjustments will be made in
subsequent steps. That may
require access to the rear area
of the unit. Plan the installation
and wiring accordingly.
!
WARNING!
Figure 1
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 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.

Amplifier Connections
Terminal Connections
!
WARNING!
Siren Amplifier Connector - As a standard feature, the Siren is equipped with a combination plug-
in terminal block/connector. To terminate the wires, strip approximately 1/4" of insulation from the
end of each wire and insert it in the appropriate hole in the terminal block. Tighten the setscrew and
proceed to the next connection.
Should you ever have to remove the unit, pull the terminal block straight out. It will unplug from the
unit, leaving the wiring in place.
COM - Connect to the wire from speaker terminal 1.
SPKR - Speaker - Connect to the wire from speaker terminal 2.
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(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 otherrecommendations 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.
NOTE: When using two 100W (11 ohm) speakers in parallel, correct phasing is important and can
be accomplished by connecting both speaker terminals marked " 1 " to the COM terminal and both
speaker terminals marked " 2" to the SPKR terminal. Also refer to the wiring diagram on page 14.
REMOTE - Remote switch (Horn ring or foot switch). Circuit can be configured for both ground
(earth) or positive signals. A horn ring transfer circuit is standard in all 3990 series. Connect to the
"REMOTE" terminal on the Lighting Control Section terminal block. Unit is configured for a ground
(earth) at the factory. See page 8 for details on configuring for a +12V input.

!
WARNING!
BLTG- Provides +12V to siren backlighting. Connect to a vehicle circuit that is powered when the
ignition switch is " on ". If backlighting dimming is desired, connect to the dash lights' circuit.
Caution- If connected to the battery the backlighting will be active at all times.
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
obstructed or muffled by structural components of the vehicle. Concealed or underhood
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.
PKILL- This feature automatically deactivates siren tones when the vehicle is shifted into PARK.
Siren tones will be disabled until the vehicle is shifted out of PARK and one of the siren control
switches is selected. This circuit is activated by a negative signal. Connect this input to a circuit
that is GROUNDED (Earth) when the vehicle is shifted into PARK. It is the installer's
responsibility to determine an appropriate location in the vehicle circuitry to connect this
wire.
RRB - Connect to one side of the two-way radio speaker.
RRB - Connect to the second side of the two-way radio speaker.
InterClear® - Connect to the device or circuit that is to be activated by the InterClear feature. The
InterClear circuit is internally current limited at 1 Amp. Should your application require higher
currents, use the InterClear Power Booster Kit (# INTBS), available from your Code 3 supplier.
Power Connections
1/4" Male Quick-Connect Printed Circuit Board Terminals
+12V - Connect to a positive +12 volt DC source. It is recommended that the user protect this wire
with a 20 Amp fuse or circuit breaker located at the source. Use #14 gauge wire terminated with 1/
4" female, fully insulated quick-connect terminals only.
NEG - Connect to the negative terminal of the battery. This supplies ground (earth) to the siren. Use
#14 gauge wire terminated with 1/4" female, fully insulated quick-connect terminals only.
NOTE: A #8 stud is provided on the rear of the unit and is intended for use ONLY as a convenient
ground (earth) " tie-point " for the light bar wiring. It is not an adequate ground (earth) for the
siren or the light bar. It is recommended all ground (earth) wires attached here be
terminated with a crimp-on ring terminal.

Expansion unit is required. Refer to the diagram on page 11 for interconnection details.
The 3992XAMP may also be used with the RLS 3997, 3998 and 3999 sirens by using the same
basic interconnection method shown on page 11.
SETUP AND ADJUSTMENT
All of the adjustments and setup switches are located on the amplifier unit. Make these
adjustments and set the switches to the desired position prior to securing the amplifier in it's final
mounting location. (see wiring diagram, page 15).
Audio Adjustments
Radio Rebroadcast Adjustment - Place the selector switch in the RADIO position. The trimmer
located on the rear panel of the siren sets the maximum level RRB will reach with the knob fully
clockwise. To adjust properly, set the volume knob fully clockwise and adjust the trimmer such that
normal two-way radio volume inside the vehicle produces the desired volume outside the vehicle.
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 and adjust the trimmer
while keying the microphone until the maximum volume
out of the speaker is such that there is no feedback and is
intelligible.
Remote Input - The remote input can be configured to
accept either a positive +12V or negative GND ( Earth )
signal for actuation. All 3990 series sirens are shipped
setup to accept the GND (Earth) signal present on most
vehicles from the vehicle horn switch. To reconfigure the
Remote Input to accept a +12V signal the amplifier cover
must be removed (see exploded view, page 20). Move
both jumpers towards the "+ " position. Refer to detail "A"
for a complete illustration.
Siren Mode Selector Switch (located on the siren
amplifier, rear panel)
The siren has two distinct modes, Hit-N-Go and Scroll. Set
rear panel slide switch, Figure 2, to the desired mode by
sliding left or right. See operation section for a detailed
description of operation in each mode.
P.A. Volume Knob
This control adjusts the level of the P.A. audio produced
when keying the microphone and speaking into it. This control also controls the Radio Rebroadcast
level when in the " RRB " switch is on. (see SETUP, Radio Rebroadcast Adjustment).

Operation
IMPORTANT !
The Model 3992 Siren has two distinct modes of operation. These are Hit-N-Go mode and
SCROLL mode. The desired mode of operation can be selected via the amplifier rear panel slide
switch. Each mode will affect the siren operation as described below. The Hit-N-Go mode should be
most familiar to existing users.
The Park Kill features will, in some cases, prevent the siren from producing siren tones. The
siren will not produce tones when the vehicle is in "PARK" if the PKILL feature has been connected.
To test the siren tones the vehicle must not be in "PARK". The following assumes that PKILL has not
been activated.
Operation - Hit-N-Go Mode Selected
The Hit-N-Go mode is designed to allow the user to instantly change siren tones by utilizing the
Remote input on the siren. By depressing the switch connected to the Remote input of the siren (usually the
vehicle Horn Ring switch), the user can cause the siren to change tones for an eight second period after
which time the siren will revert to the previous tone. The InterClear output will also be activated during this
period.
Function Description
RRB - In the RADIO position, the audio from the 2-way radio is rebroadcast over the siren speaker.
Note, all siren tone functions are disabled in this mode. Hhowever, the AIRHORN function will operate
normally.
STANDBY - This is the standby mode. If the MANUAL button is depressed the Manual wail tone will
ramp up until it reaches a peak then ramp down when released. If the AIR HORN button is depressed,
the Air Horn sound will be produced.
WAIL - Rotating the selector switch to the WAIL position will cause the siren to produce the Wail
tone. Depressing the AIR HORN button will produce the Air Horn sound and when released the siren will
resume the Wail tone. If the MANUAL button is depressed the Manual wail tone will ramp up until it
reaches a peak then ramp down when released then resume the selected tone. The Remote/Horn Ring
input will activate the Interclear output and cause the siren tone to either scroll to the next mode or change to
Yelp for 7 seconds, depending on the position of the SCROLL/HIT&GO switch.
YELP - Rotating the selector switch to the YELP position will cause the siren to produce the Yelp
tone. Depressing the AIR HORN button will produce the Air Horn sound and when released the siren will
resume the Yelp tone. If the MANUAL button is depressed the Manual wail tone will ramp up until it
reaches a peak then ramp down when released then resume the selected tone. The Remote/Horn Ring
input will activate the Interclear output and cause the siren tone to either scroll to the next mode or change to
HyperYelp for 7 seconds, depending on the position of the SCROLL/HIT&GO switch.
HI-LO - Rotating the selector switch to the HILO position will cause the siren to produce the HILO
tone. Depressing the AIR HORN button will produce the Air Horn sound and when released the siren will
resume the HILO tone. If the MANUAL button is depressed the Manual wail tone will ramp up until it reaches
a peak then ramp down when released then resume the selected tone. The Remote/Horn Ring input will
activate the Interclear output and cause the siren tone to either scroll to the next mode or change to HyperLO
for 7 seconds, depending on the position of the SCROLL/HIT&GO switch.

Push-to-Talk (PTT) Microphone Switch - Keying
the microphone will automatically override whatever mode
the siren is in and broadcast public address messages
over the siren speaker.
MANUAL Push-button Momentary Switch Produces the Manual tone as described above.
AIR HORN Pushbutton Momentary Switch -
Produces the Air Horn tone as described above.
"Wail" and "Yelp" tones are in some cases (such as in the state of California)
!
WARNING!
SLIDE SWITCH (Manual / AIR HORN) - The slide switch located on the front of the siren amplifier
(see Figure 3) selects the function for the REMOTE (external switch) circuitry. When the siren is in standby
mode and switch is to the right, the Horn Ring circuitry remotely "depresses" the AIR HORN button and it
produces the effects outlined above. When the slide switch is to the left, it allows the REMOTE circuitry to
remotely "depress" the MANUAL push-button with a similar result.
the only recognized siren tones for calling for the right of way. Ancillary tones
such as "Air Horn", "Hi-Lo", "Hyperyelp", and "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 an emergency
vehicle.

Operation - Scroll Mode Selected
The " Scroll " mode is designed to allow the user to scroll through Wail, Yelp, HyperYelp and AIR
HORN tones by utilizing the Remote input on the siren. This will usually be connected to the vehicle Horn
Ring circuit. The user can use the Horn Ring to sequence through Wail, Yelp and Hyperyelp by applying a
quick, sharp tap on the horn. Additional taps will scroll the siren to the next tone. The InterClear output will
also be activated for an eight second period following each tap of the Horn Ring switch. Depressing the horn
for longer periods will produce AIR HORN tone and deactivate the InterClear output.
When the Scroll Off option is purchased, the Remote input may be used to activate the siren from the
Standby mode. In this case the Scroll feature will operate as described above except that the siren will scroll
through WAIL, YELP, HYPERYELP & STANDBY modes. Holding the remote switch for a longer period will
still cause the siren to switch to the Air Horn tone. When the siren is not in Standby mode (the siren is
operating in any mode which was invoked by the either the Scroll Up or Scroll Down switches on the 3992
control panel), the scroll feature will operate as previously described.
Function Description
RRB - In the RRB position, the audio from the 2-way radio is rebroadcast over the siren speaker.
Note, all siren tone functions are disabled in this mode. Hhowever, the AIRHORN function will operate
normally.
STANDBY - This is the standby mode; no siren tones are produced in this position except when the
MANUAL button is depressed the Manual wail tone will ramp up until it reaches a peak then ramp down when
released. If the AIR HORN button is depressed, the Air Horn sound will be produced.
9
WAIL - This mode produces the Wail tone. Depressing the MANUAL button will now produce Manual
wail tone and ramp up until released. Depressing the AIR HORN button will produce the Air Horn sound. The
siren can be scrolled in this position as described above. The Remote/Horn Ring input will also activate the
Interclear output for 7 seconds.
YELP - This mode produces the Yelp tone. Pushing the MANUAL button will now produce the
Manual wail tone and ramp up until released. If the AIR HORN button is pushed, the AIR HORN sound will be
produced. The siren can be scrolled from this position as described above. The Remote/Horn Ring
input will also activate the Interclear output for 7 seconds.
HI-LO - This position produces the Hi-Lo tone. Pushing the MANUAL button will produce the Manual
Wail tone until released. If the AIR HORN button is pushed, the AIR HORN sound will be produced and when
released the siren return to Hi-Lo. The siren cannot be scrolled from this position. The Remote/Horn Ring
input will activate the Interclear output and cause the tone to change to HyperLo for 7 seconds.
Push-to-Talk (PTT) Microphone Switch - Keying the microphone will automatically override
whatever mode the siren is in and broadcast public address messages over the siren speaker.
MANUAL Pushbutton Momentary Switch - Produces the Manual tone as described above.
AIR HORN Pushbutton Momentary Switch - Produces the Air Horn tone as described above.
MANUAL / AIR HORN SWITCH - The MANUAL / AIR HORN slide switch located on the front of the
siren amplifier, Figure 3, selects the function for the REMOTE (external switch) circuitry when the siren is in
standby mode. When the siren is in standby mode and switch is to the right, the Horn Ring circuitry remotely
"depresses" the AIR HORN button and it produces the effects outlined above. When the slide switch is to the
left, it allows the REMOTE circuitry to remotely "depress" the MANUAL pushbutton. This causes the effects
described above to occur. When in the "Scroll " mode this switch has no effect unless in STANDBY
position.
LED STATUS INDICATOR - The green LED status indicator indicates the siren amplifier is on when
lighted; off or standby mode when unlighted.
