Warnings to Users
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 he can operate the system without
taking his 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.
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.
