2 ES100, ES100-DEU, and ES100-UNI 100 Watt Speakers
• Be sure the siren amplifier and speaker(s) in your installation have compatible wattage
ratings.
• In order for the electronic siren to function properly, the ground connection must be made
to the NEGATIVE battery terminal.
• Sound output will be severely reduced if any objects are in front of the speaker. If
maximum sound output is required for your application, you should ensure that the front
of the speaker is clear of any obstructions.
• Install the speaker(s) as far forward on the vehicle as possible, in a location that provides
maximum signaling effectiveness while minimizing the sound reaching the vehicle’s
occupants. Refer to the National Institute of Justice Guide 500-00 for further information.
• Mounting the speakers behind the grille will reduce the sound output and warning
effectiveness of the siren system. Before mounting speakers behind the grille, make
sure the vehicle operators are trained and understand that this type of installation is less
effective for warning others.
• Sound propagation and warning effectiveness will be severely reduced if the speaker is
not facing forward. Carefully follow the installation instructions and always install the
speaker with the projector facing forward.
• DO NOT install the speaker(s) or route the speaker wires where they may interfere with
the operation of airbag sensors.
• Installation of two speakers requires that you wire the speakers in phase.
• Never attempt to install aftermarket equipment, which connects to the vehicle wiring,
without reviewing a vehicle wiring diagram, which is available from the vehicle
manufacturer. Insure that your installation will not affect vehicle operation and safety
functions or circuits. Always check vehicle for proper operation after installation.
• DO NOT install equipment or route wiring or cord in the deployment path of an airbag.
• Locate the control head so the vehicle, controls, and microphone can be operated safely.
• When drilling into a vehicle structure, be sure that both sides of the surface are clear of
anything that could be damaged.
After Installation
• After installation, test the siren system and light system to ensure that it is operating
properly.
• Test all vehicle functions, including horn operation, vehicle safety functions and vehicle
light systems, to ensure proper operation. Ensure that installation has not affected vehicle
operation or changed any vehicle safety function or circuit.
• After testing is complete, provide a copy of these instructions to the instructional staff and
all operating personnel.
• File these instructions in a safe place and refer to them when maintaining and/or
reinstalling the product.
Failure to follow all safety precautions and instructions may result in property
damage, serious injury, or death to you or others.
