DANGER!

Sirens produce extremely loud emergency warning tones! Exposure to these tones without proper and adequate hearing protection, could

cause ear damage and/or hearing loss! The Occupational Safety & Health Administration (www.osha.gov) provides information necessary to determine

safe exposure times in Occupational Noise Exposure Section 1910.95. Until you have determined the safe exposure times for your specific application,

operators and anyone else in the immediate vicinity should be required to wear an approved hearing protection device. Failure to follow this

recommendation could cause hearing loss!

•

Warnings to Installers

Whelen’s emergency vehicle warning devices must be properly mounted and wired in order to be effective and safe. Read and follow all of Whelen’s written
instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for
when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate the system without
taking their eyes off the roadway.   Emergency warning devices can 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  vehicle
damage,  including  fire.  Many  electronic  devices  used  in  emergency  vehicles  can  create  or  be  affected  by  electromagnetic  interference.  Therefore,  after
installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other
components  within  the  vehicle.  Never  power  emergency  warning  equipment  from  the  same  circuit  or  share  the  same  grounding  circuit  with  radio
communication equipment. 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. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted. This
device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any. Any device mounted in the deployment
area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its
mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a
method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow
instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. 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.

Warnings to Users

Whelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and
personnel.   However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other
drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely
before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning
devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible
warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility
to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations prior to the use of
any  emergency  vehicle  warning  device.  Whelen’s  audible  warning  devices  are  designed  to  project  sound  in  a  forward  direction  away  from  the  vehicle
occupants.  However,  because  sustained  periodic  exposure  to  loud  sounds  can  cause  hearing  loss,  all  audible  warning  devices  should  be  installed  and
operated in accordance with the standards established by the National Fire Protection Association.
