Automotive: Other
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.

Introduction....
The Whelen LiFe model LF35 portable scene light features a Lithium
Iron Phosphate (LiFePO4) battery. This type of battery provides efficient
and long-lasting energy using the safest, most environmentally friendly
technology available. In addition, Lithium Iron Phosphate batteries are
capable of up to 5 times as many charge cycles as traditional Lithium
Ion (LiCoO2) batteries!
For maximum battery life, there are precautions that must be followed
to ensure long battery life. Be sure to follow the information contained in
this manual carefully.
Installation
1. Select a mounting location for the IIC (Intelligent Inductive
Charger) base. The base may be mounted on any smooth, flat
surface of ambient temperature. This surface can be either
horizontal or vertical (provided the base is properly oriented).
IMPORTANT! The location selected must not allow the LF35
to be exposed to temperatures above 140°F or below -4°F.
This will cause permanent damage to the battery and void the
warranty.
2. Position the base against the proposed mounting surface. When
determining the location for the base, remember there needs to be
sufficient room for the LF35 to be easily removed from and
returned to the base for charging (see below). Additionally, the
Release Button/Diagnostic Display needs to be clearly and readily
visible.
3. With the base in position, mark the locations of the four mounting
holes with an awl, marker or similar tool. Remove the base from
the mounting location and using a 1/4 inch bit, drill 4 mounting
holes. Be sure to deburr these holes before continuing.
4. Return the base to its mounting location and using the hardware
provided, secure the base to its mounting surface.
Wiring
DC chargers - Using appropriately sized wire, extend the wires coming
from the base to an ignition controlled, 12VDC circuit capable of
accommodating a current draw of 5 amps. The circuit used should be
fused at 7.5 Amps. IMPORTANT! Failure to use an ignition
controlled circuit could, over time, result in vehicle battery drain.
AC Chargers - AC chargers (120/240 VAC) do not require any special
wiring. The base features an AC adaptor and includes a removable
power cord that plugs into a standard AC receptacle.
Operation
After installation of the charging base has been completed, mount the
LF35 onto the base. Orient the LF35 so that the light is facing away
from the release button/diagnostic display. Place the LF35 onto the
base so that the four, metal, mounting tabs are located just ahead of the
mounting tab retainers. Slide the LF35 backwards until it fully engages
the mounting release button with a ‘click’.
Once the LF35 is latched into position, the IIC will evaluate the battery
state and report its condition by illuminating the Release Button in one
of four colors. Each color represents a different property of the battery
and serves to keep the user informed as to the battery’s state:
RED - Indicates that the LF35 is properly positioned and the battery
is charging.
GREEN - Indicates that the battery has been fully charged. Note: This
color may remain lit for a few moments after the LF35 has
been removed from the charger.
AMBER - Indicates that the temperature of the LF35 is outside its
acceptable range (140° to -4°F). The user must
immediately move the light into an area within the
acceptable operating range.
BLUE - Alerts the user that a metal object has been placed on or
near the charger and should be removed. After removal,
wait for the Blue light to go out before placing the LF35
in the charger. This may take up to 30 seconds. Do not
place any object other than the LF35 on the charger!
While the LF35 is on its base, the battery is being constantly monitored
and charged as needed. The translucent release button doubles as the
diagnostic display and provides important information about the state of
the battery. Note that the LF35 can not be activated while on the
base.

Operating Modes
The LF35 can be used in one of three operating modes. As outlined in
their descriptions, the duration of each mode is estimated using a 76°F
ambient temperature. As the temperature moves away in either
direction, the estimated battery life will diminish. The further away it
moves, the more significant the reduction of usable battery life.
The modes are as follows
High Power High power mode produces the brightest, most
intense light. To turn the light on in high power mode,
press and release the power button.
In this mode, a fully charged battery will last for
approximately 3 hours of continuous use.
Battery Saver Battery Saver mode is used to extend battery life
when a less intense light output is acceptable. To
change to Battery Saver mode, turn the light on in
high power, then press and hold the power button.
When you see the light output has been reduced,
release the button.
In this mode, a fully charged battery will last for
approximately 6 hours of continuous use.
Alert Mode Alert mode produces a flashing light. To turn the light
on in alert mode, with the power off, press and hold
the power button until the light begins to flash.
In this mode, a fully charged battery will last for
approximately 8 hours of continuous use.
IMPORTANT! While the LiFe portable light is
capable of flashing, it is not a warning light!
Critical Mode When there is approximately 15 minutes of usable
battery life left, the light will automatically switch
to critical mode. Until the battery has been
recharged, no other mode of operation is
available.
During Critical mode, light output is reduced to
10% of full intensity.
When the light has switched to critical mode, it
must be recharged before it can be returned to
service.
ONCE THE LF35 HAS SWITCHED TO CRITICAL
MODE, IT WILL TAKE APPROXIMATELY 6 HOURS
TO FULLY CHARGE THE BATTERY.
Angle Adjustment
The angle of the projected light may be adjusted as needed by rotating
the Angle Adjustment Knob. The total sweep is 180° in 15° increments.
