Installation Guide:

L51 & L52 Series LED Beacon

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.

Permanent Mount:

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.

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 using a 3/8” drill bit. Remove any burrs from the wire access hole and
install a rubber grommet (customer 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 first through the base seal and then through the cable access hole.
Place the base (with seal) 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.

Magnetic Mount (optional):

WARNING: The use of any magnetically mounted warning device on the
outside of a vehicle in motion is not recomended and is at the sole risk and
responsibility of the user.

Magnetic: Place the beacon onto a flat, metal surface surface and plug it into the

vehicle cigar lighter.

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

Operation:

Scan-Lock™ - Activate the RED wire to turn on the beacon. Activate the WHT/VIO

wire for less than 1 second and release to cycle forward through patterns. Activating
the WHT/VIO wire for more than 1 second will cause the lighthead to cycle backward
through patterns. When the desired pattern is displayed, allow it to run for more than
5 seconds. The lighthead 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. See below for pattern information.

Sync - To sync two lightheads, configure both lightheads to display the same Phase
1 pattern. With the power off, connect the GREY wires from each lighthead together.
When the lightheads are activated, their patterns will be synchronized. To configure
the two lightheads to alternate their patterns, advance the pattern of either lighthead
to the Phase 2 mode of the current pattern.

The following example will demonstrate how to use the SYNC feature with more than
2 lightheads. In this sample system, there are 4 lightheads. 2 are mounted on the
rear, driver side of the vehicle and 2 mounted on the rear, passenger side of the
vehicle.

With all the wiring complete, turn on the 4 lightheads. As shipped from the factory, all
the lightheads will simultaneously display the same pattern (SignalAlert 75 Phase 1).

To configure, for example, the passenger side lightheads to alternate with the driver
side lightheads, change the flash patterns for either the passenger or driver side
lightheads to Phase 2 mode of the same pattern. Do not SYNC more than 8 (eight)

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.
