Introduction
The Model 99XXX, 98XXX, 92XXX, and 95XXX Series 90 Strobe Beacons represent the latest advances in state-of-the-art 360 degree strobe
warning technology based on years of research and testing. The latest MOSFET technology and advanced design provide more efficient
operation, meaning superior performance, reliability and longer life.
The use of this or any warning device does not insure that all drivers can or will observe or react to an emergency warning signal. Never take the right-of-way for granted. It is your responsibility to be sure you can
proceed safely before entering an intersection, driving against traffic, responding at a high rate of speed, or
walking on or around traffic lanes.
The effectiveness of this warning device is highly dependent upon correct mounting and wiring. Read and follow
the manufacturer’s instructions before installing or using this device. The vehicle operator should insure daily
that all features of the device operate correctly. In use, the vehicle operator should insure the projection of the
warning signal is not blocked by vehicle components (i.e.: open trunks or compartment doors), people,
vehicles, or other obstructions.
This equipment is intended for use by authorized personnel only. It is the user’s responsibility to understand and
obey all laws regarding emergency warning devices. The user should check all applicable city, state and
!
WARNING!
federal laws and regulations.
Public Safety Equipment, Inc., assumes no liability for any loss resulting from the use of this warning device.
Proper installation is vital to the performance of this warning device and the safe operation of the emergency
vehicle. It is important to recognize that the operator of the emergency vehicle is under psychological and
physiological stress caused by the emergency situation. The warning device should be installed in such a
manner as to: A) Not reduce the output performance of the system, B) Place the controls within convenient
reach of the operator so that he can operate the system without losing eye contact with the roadway.
Emergency warning devices often 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 severe vehicle damage, including fire. Incandescent
lamps are extremely hot, allow to cool completely before attempting to remove.
Any electronic device may create or be affected by electromagnetic interference. After installation of any
electronic device operate all equipment simultaneously to insure that operation is free of interference. Never
power emergency warning equipment from the same circuit or share the same grounding circuit with radio
communication equipment.
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.
Unpacking & Pre-installation
Remove the beacon from the box and examine the unit for transit damage. A battery (+12/24 VDC) or battery charger may be used to test
the beacon. To test, connect the black wire to the negative (earth) terminal of the battery or battery charger. Touch the red wire to the
positive (+12/24 VDC) terminal and verify the unit's operation. Reversing the power connections will activate the reverse polarity
protection, resulting in no light output.
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
!
WARNING!
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. Front or rear grille/bumper placement must
avoid interference with SRS sensors. Mounting the unit inside the vehicle by a method other than the 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.

Installation & Mounting
The Model 99XXX, 98XXX, 92XXX, and 95XXX Strobe Beacons are shipped fully tested and ready for installation. Refer to Figure 1 for
attachment points. Connect wiring as shown in Figure 2. Grommets and sealant should be used to keep water out of your vehicle.
New Installation Mounting
Use A, B & C mounting holes. Be sure "Rear" is placed facing the rear of vehicle.
Universal Replacement Mounting
(option)
If replacing existing Whelen/TT/Austin strobe products, use A,
B & D mounting holes. Remove lens and punch hole "D" using
a punch or drill bit. Use CAUTION not to damage the PCB. Be
sure "Rear" is placed facing rear of vehicle.
Magnetic Mounting (option)
Use optional magnetic mount for temporary mounting of the unit to
stationary vehicles.
1) Rust Stains: Magnetic mounting is not intended as permanent mounting for beacons. Long duration usage of
any magnet will expose the high iron content of the steel, thereby causing rust. The device should by removed
when not used to prevent rust stains. Metallic debris collected by the magnet will also contribute to rust stains.
Insure that the magnet is kept clean.
!
WARNING!
2) Surface rust stains can usually be removed with chrome polish, available at most auto part stores.
3) As with any magnetically-mounted warning device, its use on the exterior of a moving vehicle is at the sole
discretion and responsibility of the user.
Magnetic mount products provide a secure, temporary installation in most circumstances and is recommended
for stationary use only. For maximum warning signal, mount the beacon on the highest possible flat, level
surface of the vehicle.

Pipe Mounting
The Strobe base will accept a standard 1" NPT pipe. Hand tighten the beacon base on the pipe thread until the pipe bottoms out
inside the unit. DO NOT OVER-TIGHTEN. Excessive torque may crack the beacon base. Secure with a locknut to prevent unit
from coming loose. Use the appropriate reducer to mount to 3/4" or 1/2" pipe.
!
WARNING!
Using non-factory specified screws and/or mounting brackets and/or the improper number of screws may
result in failure of mounting system and severe damage to vehicle as well as loss of warranty coverage on the
equipment.
