Introduction
!
The enhanced 3890 series siren is an improved series of electronic sirens that has been designed to meet
the needs of all emergency vehicles. This series of sirens incorporates the popular packaging and features
of the original Mastercom siren with microprocessor based circuitry and MOSFET technology. Most of the
original Mastercom features are available along with many new added features that are not available on any
other Code 3 siren such as; Park Kill, Instant "ON", Adj. Backlighting, " 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
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.
Code 3, 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.

between the siren and the light control circuits that permits
automatic siren tones only when the progressive switch is in Level 3 or in Level 2 or 3 (user selectable - works
in conjunction with the horn transfer relay). This feature is used in jurisdictions that require warning lights to be
on before the siren is activated.
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 an action occurs such as moving the selector switch to
STANDBY, returning lighting level switch to position one or keying the microphone. Any action will enable the
siren tones to function again with the exception of the auxillary lighting pushbuttons.On lighting models this also
drops-out the Level 3 lighting output for a power- down mode when in park.
Adjustable Backlighting- Backlighting is independent of siren power. Allows connecting to dimmer if desired.
Radio Power- Allows user to power the two-way radio from the siren when the ignition is "OFF".
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.
Lighting Level "3 " Drop-out- When vehicle is shifted to PARK and the PKILL feature is connected, Level 3
lighting will drop-out. This is indicated by the "red" LED exstinguishing. This is a power down mode and can be
defeated by setting the 4 -position rear dip switch to the PKILL "OFF" position on the lighting board.
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 Airhorn 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 Mastercom users. A seven second override is
standard for all tones when activated by the Manual button or the Remote input.See OPERATION section for
details.
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 panel that informs the operator of the status of his siren at
all times.
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), and remotely activates the MANUAL or AIR HORN (if
supplied) function. Selection is made via the front panel slide switch.The siren is factory set for a GND
(Earth) signal and may be reconfigured to accept a positive signal. See Set-up and Adjustments section
for details.
Tone Priority/Manual Wail - The following tones are produced while pushing the MANUAL Push-button or
triggering the user-supplied REMOTE siren switch:
Manual Wail when the MANUAL Push-button is depressed while the rotary switch is in the STANDBY position.
Yelp when the MANUAL Push-button is depressed while the rotary switch is in the WAIL position.
HyperYelp when the MANUAL Push-button is depressed and the rotary switch is in the YELP position.
HyperLo when the MANUAL Push-button is depressed and the rotary switch is in the HI-LO position.
Noise Cancelling Microphone - Wired in microphone that is easily unplugged internally for service or
replacement.
Power Distribution Section - A three level progressive
switch for primary warning light system control plus 4 pushon/push-off auxiliary switches that are user convertible to
momentary action ('L4 models). The unit may also be
purchased with 6 auxiliary switches ('L6 models).
Each auxiliary switch can be custom labeled with the
supplied label kit. Each label is backlit and increases
intensity when activated to alert the operator. Each position
of the progressive switch has its own indicator LED.
Horn Ring Transfer - ('L models only) Built in horn transfer
relay that may be activated at Levels 2 and 3 of the warning
light progressive switch. Point of activation is customer
selectable with the rear panel DIP switch.

Unpacking & Pre-installation
After unpacking your 3890 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
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.
WARNING!
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.

Installation & Mounting
The 3890 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. 2). Ease of operation and
convenience to the operator should be the prime consideration when mounting the siren and
controls.
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
carriage bolts, washers, and nuts supplied. See Figure 2 for assembly and positioning details. Note
that once the unit is installed, removal involves only loosening, not removing, the acorn nuts. Use of
1/4 - 20 HEX head bolts can damage slots and prevent easy removal of the unit.
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.

Amplifier Connections
Siren Amplifier Connector - As a standard feature, the Siren and Auxiliary sections ('L4 & 'L6
models) of your unit come 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. Recommend using a screwdriver with a 1/8" wide blade
with a 6" shaft such as an Xcelite(C) R186 or equivalent rather than a 4 1/2" adjustment screwdriver
to ensure proper torque on the screws. Tighten the set-screw 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.
WARNING!
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 other
recommendations of the manufacturer and be protected from moving parts and hot surfaces.
Looms, grommets, cable ties, and similiar 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.

WARNING!
!
Terminal Block Connections
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 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 ot
her emergency vehicles.
APPROPRIATE TRAINING OF VEHICLE OPERATORS IS RECOMMENDED TO ALERT
THEM TOTHESE PROBLEMS AND MINIMIZE THE EFFECT OF THESE PROBLEMS
DURING OPERATIONS.
