SmartSiren Platinum Series
All effective sirens and horns produce loud sounds (120 dB) that may cause permanent hearing loss.
Always minimize your exposure to siren sound and wear hearing protection. Do not sound the siren
indoors or in enclosed areas where you and others will be exposed to the sound.
• Federal Signal siren amplifiers and speakers are designed to work together as a system. Combining
a siren and speaker from different manufacturers may reduce the warning effectiveness of the siren
system and may damage the components. You should verify or test your combination to make sure
the system works together properly and meets federal, state and local standards or guidelines.
During Installation
• Do NOT get metal shavings inside the product. Metal shavings in the product can cause the system
to fail. If drilling must be done near the unit, place an ESD-approved cover over the unit to prevent
metal shavings from entering the unit. Inspect the unit after mounting to be sure there are no
shavings present in or near the unit.
• Do NOT connect this system to the vehicle battery until ALL other electrical connections are made,
mounting of all components is complete, and you have verified that no shorts exist. If wiring is
shorted to vehicle frame, high current conductors can cause hazardous sparks resulting in electrical
fires or flying molten metal.
• To avoid a battery explosion, always disconnect the negative battery cable first and reconnect it last.
Avoid causing a spark when connecting near tot to the battery. The gases produced by a battery can
cause a battery explosion that could result in vehicle damage and serious injury.
• 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 which provides maximum
signaling effectiveness and minimizes 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 wiring speakers in phase.
• Never attempt to install aftermarket equipment, which connects to the vehicle wiring, without
