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.

• 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 any 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.

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

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

• If this product contains strobe light(s), halogen light(s) or high-intensity LEDs, do not stare directly into these
lights at a close distance. 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. Lens 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.

• FAILURE TO FOLLOW THESE SAFETY PRECAUTIONS AND INSTRUCTIONS COULD RESULT IN DAMAGE TO
THE PRODUCT OR VEHICLE AND/OR SERIOUS INJURY TO YOU AND YOUR PASSENGERS!

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

as good air circulation and heat dissipation.

• The flasher is not waterproof. The mounting area must be dry and free from elements that could damage the unit (road salt, sand, snow).

• The flasher should not be exposed to excessive heat.

• The mounting area should be easily accessible for wiring and service purposes.

• Mounting the flasher to a metal surface is recommended for optimum heat dissipation.

• 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 the mounting holes.

• Select a location towards the middle of the cab.

• Be sure that the mounting location is a minimum of 8” from the cab floor.

• The flasher should be mounted on as flat a surface as possible.

DOT-LED®: Included are two, 10-12 gauge and

twenty four, 14-16 gauge Faston connectors to
connect your lighting options to the flasher and to
connect your power wires.

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
battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!

IMPORTANT! Before returning the vehicle to
active service, visually confirm the proper
operation of this product, as well as all vehicle
components/equipment

Flasher Connection & Operation:

Connect your lighting options (Lightheads, beacons
etc...) to the flasher as shown. Connect the positive
wire of the lighting option to outputs 1 thru 8
(Each outlet will handle 5 AMPS PEAK). Connect
the negative wires of your lighting options to any of
the ground terminals. All terminals take a Faston
connector (supplied). Applying +12V DC to the
positive wire will activate its outlet or function (See
wiring diagram).

NOTE: Keep in mind that each control wire
activates two outlets each. Be sure to connect
lights that need to be on the same circuit accordingly, such as 2 front lightheads or both rear options would be. Fuse the control wires at 1 AMP each.

Hi/Low Power: This feature allows the user to step the unit down to low power operation for nighttime use

Option 1 / Latching Mode: By applying +12V DC to the "Hi/Low Power Control Wire” for less than 1 second, the system is latched into low power operation. The unit
must be turned off and then back on to restore normal high power (Momentary Switch).

Option 2 / Level Mode: Applying +12V DC to the "Hi/Low Power Control Wire” for more than 1 second holds the system in low power until the voltage is removed
(Toggle Switch).

Photocell (optional): If you have the photocell option, plug the BLACK wire into the negative photocell terminal, the RED wire into the positive photocell terminal and
the VIOLET wire into the low power terminal of the flasher (see wiring diagram). With the photocell hooked up, the system will switch to low power automatically at
night. Mount the photocell where it will be exposed to daylight, away from any vehicle lighting.

Scan-Lock™:

Scan-Lock allows the user to choose from several flash patterns. The entire system will display the pattern you choose (All outputs will display the same pattern).

TO CYCLE FORWARD THROUGH FLASH PATTERNS: Activate any of the outputs by applying power. With the outputs activated apply +VBAT to the Scan-Lock wire
for less than 1 second and release. Repeat to advance to next pattern.

TO CHOOSE A PATTERN: While cycling through the available flash patterns allowing a pattern to run for at least 5 seconds will configure it as the default pattern.
Now when activated the entire system will display this flash pattern.

TO RESET TO THE FACTORY DEFAULT PATTERN: Turn off all functions. Apply +VBAT to the Scan-lock wire while turning any of the functions back on. The system
is now restored to its factory default pattern.

Available Flash Patterns:
SignalAlert™ All outputs flash simultaneously > 4 - CometFlash® 75 Outputs 1, 2, 3 & 4 alternate with 5, 6, 7 & 8 > 5 - CometFlash® 75 Outputs 1, 3, 5 & 7 Alternate
