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.
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 respon-
sibility 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.
