WARNING
Sirens produce loud sounds that may damage hearing
• Wear hearing protection when testing
• Use siren only for emergency response
• Roll up windows when siren is operating
• Avoid exposure to the siren sound outside of vehicle
Read all instructions and warnings before installing and using.
IMPORTANT:

Introduction
The 4000 series of electronic sirens have been designed to meet the needs of all emergency vehicles. This
series of sirens incorporates many popular features of the Code 3® siren line with microprocessor based
circuitry and MOSFET technology.
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 intersec
tion, driving against traffic, or responding at a high rate of speed.

WARNING!
SIREN PRODUCTS:
The effectiveness of this warning device is highly dependent upon correct mounting
and wiring. Read and follow the manufacturer’s instructions before installing ng
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.
Standard Features
The 4000 series of E-CON sirens consist of remotely mounted siren amplifier is operated by a user supplied
controls. The models are as follows:
4012 - 12V, No Public Address
4013 - 12V, With Public Address
4024 - 24V, No Public Address
4025 - 24V, With Public Address

Instant-On- Applying Ground to the ACTIVEZ terminal will cause the siren to operate in Day power mode. When
either the Police or Emergency Medical Siren Tones are selected (SW1 set to 0 or 2), applying Ground to both
the ACTIVEZ and the NUIT terminal will switch to Night power mode. Pressing the microphone Push-to-Talk
(PTT) button on models 4013 and 4025 will activate the Public Address function.
Instant Public Address - The Public Address function will override the siren function when the microphone
Push-to-Talk button is pressed (Models 4013 and 4025 only).
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.
Noise Canceling Microphone - A Plug-in noise canceling microphone (Models 4013 and 4025 only) is provided
for easy service or replacement.
Unpacking & Pre-installation
After unpacking your 4000 Series Siren, carefully inspect the unit and associated parts for any damage that may
have occurred in transit. Report any damage to the carrier immediately.
Installation & Mounting
Figure 1, Light Bar Mounting
The 4000 Series of Sirens is designed to be mounted inside a light bar or inside the vehicle. Do not mount the
siren inside the engine compartment. Mounting hardware is supplied (see Fig. 2) for mounting the amplifier
inside the light bar.
NOTE: Setups and adjustments will be made in subsequent steps that may require access to the siren. Plan
the installation and wiring accordingly.

Amplifier Connections
Siren Amplifier Connector - Refer to the Wiring Diagram in Figure 5 (page 10) for detailed
information about the amplifier connections. As a standard feature, the 4000 Series of Siren are
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, loosen the security screws and pull the terminal block
straight out. It will unplug from the siren, leaving the wiring in place.
Terminal Block Connections
-V - Connect to the negative terminal of the battery. This supplies ground (earth) to the siren. Use #14
gauge wire.
+V - Connect to a positive +12 volt DC source (+24 volts for Models 4024 and 4025). It is
recommended that the user protect this wire with a 10 Amp fuse or circuit breaker located at the
power source (5 Amp fuse for Models 4024 and 4025). Use #14 gauge wire.
NUIT - Connect to a switch which will supply ground (earth) when ON. Use #14-16 gauge wire.
ACTIVEZ - Connect to a switch will supply ground (earth) when ON. Use #14-16 gauge wire.
HP1 - Speaker - Connect to the wire from 100W ( 11 ohm ) speaker terminal 1.
HP2 - Connect to the wire from one 100W ( 11 ohm ) speaker terminal 2.
SETUP AND ADJUSTMENT
P.A. Volume Adjustment - Public Address volume is set by the sliding volume control located on
the front of the microphone. Set this control to give the desired PA Volume level. The user may
adjust this control at any time during use.
Tone Selection - Referring to Figure 2 and Figure 3 and the Siren Tone Chart, Figure 4, set the 16
position rotary switch SW1 (located inside the siren) to the number which corresponds to the desired
tone. Unless otherwise specified at the time of order, the default setting is 0 (Police).
All devices should be mounted in accordance with the manufacturer’s instructions and
!
WARNING!
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.
