Installation Guide: Century™ Mini Lightbar

Models: MC23**, MC16** and MC11**

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.

• Whelen Engineering recommends the use of waterproof butt splices and/or connectors if that connector could be exposed to moisture.

• Failure to use specified installation parts and/or hardware will void the product warranty.

• If mounting this product requires drilling holes, the installer MUST be sure that no vehicle components or other vital parts could be damaged
by the drilling process. Check both sides of the mounting surface before drilling begins. Also de-burr the holes and remove any metal shards
or remnants. Install grommets into all wire passage holes.

• If this manual states that this product may be mounted with suction cups, magnets, tape or Velcro®, clean the mounting surface with a 50/50
mix of isopropyl alcohol and water and dry thoroughly.

• Do not install this product or route any wires in the deployment area of your air bag. Equipment mounted or located in the air bag deployment
area will damage or reduce the effectiveness of the air bag, or become a projectile that could cause serious personal injury or death. Refer to
your vehicle owner’s manual for the air bag deployment area. The User/Installer assumes full responsibility to determine proper mounting
location, based on providing ultimate safety to all passengers inside the vehicle.

• For this product to operate at optimum efficiency, a good electrical connection to chassis ground must be made. The recommended
procedure requires the product ground wire to be connected directly to the NEGATIVE (-) battery post (this does not include products that use
cigar power cords).

• If this product uses a remote device for activation or control, make sure that this device is located in an area that allows both the vehicle and
the device to be operated safely in any driving condition.

• Do not attempt to activate or control this device in a hazardous driving situation.

• This product contains either strobe light(s), halogen light(s), high-intensity LEDs or a combination of these lights. Do not stare directly into
these lights. Momentary blindness and/or eye damage could result.

• Use only soap and water to clean the outer lens. Use of other chemicals could result in premature lens cracking (crazing) and discoloration.
Lenses in this condition have significantly reduced effectiveness and should be replaced immediately. Inspect and operate this product
regularly to confirm its proper operation and mounting condition. Do not use a pressure washer to clean this product.

• It is recommended that these instructions be stored in a safe place and referred to when performing maintenance and/or reinstallation of this
product.

Permanent Mounting / Bracket or Stud Mount:

This mounting style requires removal of the headliner. There may be a roof
support member that runs from the drivers to the passengers side of the
vehicle. Do not drill through this member.

Caution: Permanent mounting of this product will require drilling. Be
absolutely 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. Insert the 2 stud mounts (or brackets) under the lip in the bottom of the
extrusion. (rounded end first) and pivot the bracket so that the other end
slides under the other lip in the extrusion (Fig. 1). The mounting hardware
must be clear of the lightbar to get the bracket into the extrusion.

Fig. 1

4. Remove the lightbar and drill the mounting holes (Fig. 2) as well as the 5/
16” dia. wire passage hole. De-burr all the holes and install a rubber
grommet (customer supplied) into the wire passage hole.

5. Route the wires through the grommet and to the necessary switches and
power source as shown in the wiring diagram.

6. Secure the lightbar to the vehicle using the hardware provided. From the
underside of the mounting surface, apply RTV around each mounting
hole and the grommeted wire passage hole.

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.

Temporary Mount (Magnetic or Suction Cup):

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 prior
to mounting. 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 as standard
suction cups but are best suited to a flat, steel surface. Magnetic: Place the
lightbar onto the mounting surface and plug it into the vehicle cigar lighter.

NOTE: Insert into the base the same as the permanent mount brackets.

2. Make sure that the brackets are sitting all the way at each end of the
extrusion, then secure them with the supplied allen set screws.

3. Place the lightbar in the exact mounting location. Mark the location of the
2 (or 4) mounting holes onto the mounting surface, and the area for the
wire passage hole. This hole should be located directly below where the
wires exit the extrusion.

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 the load.
DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!

Scan-Lock™:

To operate Scan-Lock™, switch the lightbar on. Magnetic and Suction mount
models use a momentary switch on the cigar plug instead of a Scan-Lock wire.

TO CHANGE PATTERNS: To cycle forward apply +12 VDC to the WHT/VIO
wire (or switch) for less than 1 second and release. To cycle back to the
previous pattern apply +12 VDC to WHT/VIO wire for over 1 second.

TO CHANGE THE DEFAULT PATTERN: When the desired pattern is
displayed, allow it to run for more than 5 seconds. The lighthead will now
display this pattern when initially activated.

TO RESTORE THE FACTORY DEFAULT PATTERN: With power off, apply
+12 VDC to the WHT/VIO wire (or switch). While continuing to apply power to
Scan-Lock™ turn lighthead(s) on. The factory default pattern will be displayed.
