Introduction
!
The Code 3® Model 3000 Electronic Siren produces two distinct tones, "Wail" and "Yelp". Model 3050
produces three distinct tones, "Wail", "Yelp" and "Air Horn".
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, particu-
WARNING!
SIREN PRODUCTS:
larly 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.
Unpacking & Pre-installation
After unpacking your 3000 or 3050 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. Before discarding the
packaging material, check to see that you have the following:
1. Siren and Cover
2. User Parts Bag (#S91017 - Model 3000 or #S91018 Model 3050)
Installation & Mounting
Mounting
The 3000 and 3050 series sirens can be mounted anywhere in the passenger compartment that will
provide adequate ventilation. It is not recommended that the unit be placed in the direct path of heater
duct discharge. Do not mount in the engine compartment or any other area subject to high heat or
moisture.

Mount the siren with the (2) supplied #8 screws into a secured portion of

sheet metal. See Fig. 1.
Remove the backing from the adhesive faceplate and place the
faceplate over the three hole bracket, see Fig. 2. Should you wish
to install a switch for a beacon, carefully cut the faceplate with a
sharp knife from the front to expose the extra hole in the bracket
and then mount the bracket with the remaining (2) #8 screws. The
bracket should be mounted in a location that will provide
convenience for the operator.
For custom installations, such as in a console or in-dash mounting, the
three hole bracket may be used as a drilling template and the faceplate then
applied directly to the dash or console surface.
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.
WARNING!
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.
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.

Wiring
Wire should be #16 gauge, or larger for all connections to the switch, push-button (3050), and the
siren unit. Speaker wire should be #18 gauge or larger. For protection of the wiring and the siren
unit, the in-line fuse and fuseholder supplied should be located as close to the battery as practical.
For proper operation, ground the siren unit negative (earth) terminal to the vehicle frame as close to
the unit as possible. Be sure to scrape away the paint down to the bare metal.
For maximum reliability, it is recommended that all connections be soldered with 60/40 resin core
solder. Should you prefer to crimp the terminals to the wires, be sure that all crimp connections are
tight and that the wire cannot be pulled loose from the terminal. It is further recommended that
wirenut connections be soldered first.
Route all wiring in such a manner as to prevent abrasion between the wires and the metal vehicle
surfaces. Cut off and discard any excess wire.
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 similar installation hardware should be used to
anchor and protect all wiring.
