L22 LED Beacon (Encapsulated)

Models L22H*** and L22L***

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.

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. A base seal is used between the beacon base and 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.

1 Inch (NPT) Pipe Mount:

Threading for a 1 inch (NPT) pipe mounting is precast in the base
(pipe not included with beacon).

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.

Temporary Mounting (Optional):

IMPORTANT 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. Magnetic/Suction Cups mount the same
as standard suction cups 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.
Magnetic mount models do not
offer SYNC.

Mounting:

“J” Hook Mount:

This beacon is equipped to handle the “J” hook mount available on some
beacons. Be sure to use the correct “J” hook mounting holes (Fig. 1).

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.

Operation: SYNC:

To SYNC two beacons, configure both beacons to display the same
Phase 1 (Simultaneous) pattern. Turn the power off and connect the
GREY wire from each beacon together. When the beacons are activated
their patterns will be synchronized. To configure two beacons to alternate
their patterns, advance the pattern of either beacon to Phase 2
(Alternating) of the current pattern. (Not available on cigar plug models)

Hi/Lo Power: Photocell

If this beacon is equipped with photocell Hi-Lo, the beacon will
automatically step down to low power at night. This feature is optional.

Programming / Scan-Lock™ / White-Violet:

To cycle forward through all patterns: With the beacon switched on,
apply Positive (+) voltage to the WHT-VIO wire for less than 1 second and
release. To cycle backward through all patterns: Apply Positive (+)
voltage to the WHT-VIO wire for more than 1 second and release.

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.

NOTE: Cigar cord models have a momentary switch on the plug to
control Scan-Lock™ as well as an On-Off switch.
