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.

1 INCH (NPT) PIPE MOUNT:
Threading for a 1 inch (NPT) pipe mounting is precast in the base.
1. Feed power cable through the 1 inch pipe and connect the cable to
the wires of the beacon.
2. Screw the beacon into the threads on the 1” pipe, taking precaution
not to damage the connected power wires. Do not tighten base too
hard as not to damage threads on base.
PERMANENT 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 the mounting holes 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
It is also recommended that you install a rubber grommet (customer
supplied) into the wire hole to protect the wires.
3. The base seal (ITEM 21) will be used between the strobe beacon
base and the mounting surface.
4. Feed the wires first through the base seal and then through the cable
access hole and place the base (with seal) on the mounting surface
(while lining up the mounting holes in the base with the mounting
holes you drilled into the mounting surface). Secure the beacon
firmly to the mounting surface with the supplied mounting screws.
“J” HOOK MOUNT:

Operation:
Programming / Scan-Lock™ / White-Violet:
To cycle through all patterns: With the beacon switched on, apply
Positive (+) voltage to the WHITE-VIOLET wire for less than 1 second and
release to cycle forward. Apply Positive (+) voltage for more than 1 second
and release to cycle backward.
To set a pattern as default: When the desired pattern is displayed, allow
it to run for more than 5 seconds. The beacon will now display this pattern
when activated.
To reset to the factory default pattern: Turn off power. Now, while
applying Positive (+) voltage to the WHITE-VIOLET wire, turn power on.

High Power Override: Violet
This beacon is equipped with photocell Hi/Low. This means the beacon
will automatically step down to low power at night. If you wish to keep the
beacon in high power at night, ground the VIOLET wire. This will cause
the beacon to stay in high power until you remove the ground. In
applications requiring SAE compliance, this line should be permanently
grounded.
LED Diagnostic Indicator:
This strobe beacon comes equipped with an LED diagnostic indicator. If
the flash tube does not light and the LED is blinking, replace the flash
tube. If the flash tube does not light and the LED is not blinking, check the
power wires, fuse or strobe power supply. The LED is located under the
lens (Fig. 2).
Replacing the Flashtube:
1. Remove the lens screws and remove the lens.
2. While pinching the 2 clips on the sides of the flastube together, pull
the old flash tube out of the beacon.
3. Plug the new flash tube into the base and replace the lens.
