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.

IMPORTANT - This product was designed to be configured
using the WeCan system programming software. It can not be
used as a stand alone module.
WARNING! All customer supplied wires that connect to the
positive terminal of the battery must be sized to supply at
least 125% of the maximum operating current and fused ‘at
the battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!
Addressing - The network address for this module is pre-
configured to be identified in the configuration software as
“MODULE 1”. If two (2) CANEM16 modules are installed, it will
be necessary to cut the jumper wire located between J1-2 and
J1-5, on one of the modules. That module will now be identified
in the configuration software as “MODULE 2”.
Selecting a mounting location:
The expansion module has been designed to be mounted
under the hood, in the trunk or in the passenger compartment.
Regardless of the location selected, the following notes must be
observed:
• The module should be mounted on a flat surface. Be
sure that this surface is not one that either generates
or is exposed to excessive heat during normal
operation of the vehicle.
• Do not select a location where the module will be
exposed to potential damage from any unsecured or
lose equipment in the vehicle.
• The mounting area should be easily accessible for
wiring and service purposes. Be sure that the backside
of the proposed mounting surface does not hide any
wires, cables, fuel lines, etc., that could be damaged
by drilling mounting holes.
