Installation Guide:
L40 and L41 Series LED Beacons
12 & 24 Volts
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.
Warnings to Users
Warnings to Installers
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.
Safety First
This document provides all the necessary information to allow your Whelen product to be properly and safely installed. Before beginning the installation
and/or operation of your new product, the installation technician and operator must read this manual completely. Important information is contained herein
that could prevent serious injury or damage.
• Proper installation of this product requires the installer to have a good understanding of automotive electronics, systems and procedures.

CAUTION! DO NOT LOOK DIRECTLY AT THESE LED’S WHILE THEY ARE ON.
MOMENTARY BLINDNESS AND/OR EYE DAMAGE COULD RESULT!
IMPORTANT WARNING!
beacon can operate at either 12 or 24 volts and will automatically
switch to whichever voltage is applied to the power wire.
CAUTION: Permanent mounting of this product will require drilling. It
is absolutely necessary to make sure that no other vehicle
components could be damaged by this process. Check both sides of
the mounting surface before starting. If damage is likely, select a
different mounting location.
Permanent Surface Mount:
1. Use the base as a template and mark the three mounting holes off onto
the mounting surface. Remove base. In the center
between the three mounting holes, mark the
location of the wire access hole.
2. Drill mounting holes into the mounting
surface with a #16 drill bit. Drill the wire
access hole with a 3/8” drill bit. Remove
any burrs from the wire access hole and
install a rubber grommet (user supplied)
into the wire hole to protect the wires.
3. The base seal goes between the beacon
base and the mounting surface.
4. Feed the wires through the base seal and
then through the cable access hole. Place
the base on the mounting surface and align
the beacon mounting holes with the
mounting holes drilled in step 2. Secure the
beacon firmly to the mounting surface using
the supplied #10 mounting screws.
This beacon may be mounted using “J”
hooks. Be sure to use the correct “J” hook mounting holes as shown
above.
If an alternate wire path is used, drill
a .375 DIA wire passage hole. Install a
3/8” grommet (user supplied) in this
hole.
1” N.P.T. Pipe Mount (optional):
1. Remove the base gasket (if present) from the base and discard.
2. Feed beacon wires through pipe. Connect as shown in “Wiring”.
Screw the beacon onto the pipe, being careful not to pinch or strain the
wires. Hand tighten the unit onto the pipe.
Operation:
Low Power - Activate the VIOLET wire to put the beacon into low power
operation. Disable this wire to restore normal, high power operation
(toggle switch).
Photocell Low Power - If this beacon is equipped with photocell Hi-Low,
the beacon will automatically step down to low power at night.
Wiring:
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!
Temporary Mount (Optional):
WARNING: The use of any magnetically mounted warning device on
the outside of a vehicle in motion is not recommended and is at the
sole risk and responsibility of the user.
Magnetic/suction: Thoroughly clean the proposed mounting surface. For
suction cup mounting, wipe the suction cup clean, place the beacon onto
its mounting surface and apply gentle pressure to ensure a good seal has
been achieved. The Magnetic/Suction Cups mount the same way but are
best suited to a flat, steel surface. Magnetic: Place the beacon onto the
mounting surface and plug it into the vehicle cigar lighter. Temporary
mount models do not offer Low Power or SYNC.
Stud Mount (optional):
1. Remove the base gasket (if present) from the base and discard.
2. Route the wires through the hole in the center of the bracket. If desired,
a slot for an alternate wire path is provided in the base.
3. Secure the Stud Bracket onto the base using the hardware provided.
Drill wire passage and mounting holes using the information shown.
Scan-Lock™ - Activate the RED wire to turn on the beacon. To cycle
forward through patterns, activate the WHT/VIO wire for less than 1
second and release. To cycle backward through patterns, activate the
WHT/VIO wire for more than 1 second and release. To choose a pattern,
allow it to run for more than 5 seconds. The beacon will now display this
pattern when active. To reset to the factory default pattern, turn off power,
activate the WHT/VIO wire, then turn power back on. Use a normally open
momentary switch to control Scan-lock™. Cigar cord models have a
momentary switch on the plug for Scan-Lock™ and an On/Off switch.
All beacons configured to display the Phase 1 mode of a pattern will flash
simultaneously. Any beacons configured to display the Phase 2 mode of a
pattern, will alternate with any Phase 1 beacons of the same pattern.
Sync - To sync two beacons, configure both beacons to display the same
Phase 1 pattern. With the power off, connect the GREY wires from each
beacon together. When the beacons are activated, their patterns will be
synchronized. To configure the two beacons to alternate their patterns,
advance the pattern of either beacon to the Phase 2 mode of the current
pattern.
Do not SYNC more than 8 beacons.
IMPORTANT: It is the responsibility of the installation technician to
make sure that the installation and operation of this product will not
interfere with or compromise the operation or efficiency of any
vehicle equipment! Before returning the vehicle to active service,
visually confirm the proper operation of this product, as well as all
vehicle components/equipment.
