WARNING!

Sirens are an integral part of an effective audio/visual emergency warning system. However, sirens are only short range second-

ary 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.

The effectiveness of this warning device is highly dependent upon correct mounting and wiring. Read and follow the manufacturer’s instruc-

tions before installing this device. The vehicle operator should check the equipment daily to insure that all features of the device operate cor-

rectly.

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 imple-

mented 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 emer-

gency 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 con-

nections. 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.

Installation and Operation Instructions

WARNING!

• Sirens produce loud sounds that may damage hearing
