Code 3 550 Series Beacon - Manual (Page 2)

Introduction
The 550 TM beacon has a single rotating warning signal which exceeds by several times the SAE Standards set
for 360 degree rotating warning lights, and is available in permanent, magnetic, or stanchion mount
configurations.

The use of this or ant 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 federal laws and regulations.
Code 3, 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 psycho-
logical 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.
PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF
EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PER-
SONNEL AND THE PUBLIC.

Unpacking & Pre-installation
Carefully remove the beacon and place it on a flat surface, taking care not to scratch the lens.
Examine the unit for transit damage, broken lamps, etc. If it is convenient, you may wish to test the
unit before installation. To test, touch the black wire to ground (earth) and the red wire to +12 volts
D.C. A battery charger may be used for this purpose. If the vehicle has an electrical system other
than 12 volts D.C. negative ground (earth), and you have not ordered a specially wired beacon,
contact your local representative or call the factory for
instructions.
Installation & Mounting
Wiring Instructions
The Model 550 TM Beacon is designed to operate on a
12 volt D.C. negative ground (earth) system or
alternatively on a 24 volt system when specified.
Use a minimum 16 gauge wire, 14 gauge on
runs longer than 15 ft. Use "SXL" type wire in
the engine compartment. Solder all crimped
connectors and cover with shrink tubing on any
hand splices. DO NOT use insulation displacement
connectors (e.g. 3M
® Scotch Lock type connectors).
Connect the ground (earth) lead (black) to the vehicle
chassis, or preferably the negative (earth) terminal of the
battery. Bring the positive lead (red) to the user supplied
control switch, and then to the battery or to the stud on the
battery side of the starter solenoid or alternator. Install a fuse or
circuit breaker of 10 amps capacity
in the supply line to protect the vehicle's wiring system against short circuits. Locate the wire exit to
the rear of the beacon.
