OVERVIEW
WARNING
Failure to follow the safety precautions below may result in property damage,
serious injury, or death to you, to passengers, or to others.
SOUND HAZARDS
–
Your hearing and others’, in or close to your
vehicle with EH-100 equipped, could be damaged by the loud sound. This can
occur from exposures to loud siren/PA sounds. All sounds generated by
EH-100 may, in certain situations, cause permanent hearing loss. You should
minimize your exposure times and wearing proper hearing protection, for
hearing conservation guidance, refer to federal, state or local
recommendations.
DETRACTION WARNING
–
If the unique combination of
emergency vehicle equipments installed in your vehicle has resulted in the
siren controls being installed in the position that requires the eyes of the driver
detracted from the traffics, operate controls only while your vehicle is stopped.
It is necessary to watch the traffics while in driving and recommended to
control EH-100 by touch only.
SOUND EFFICIENCY WARNING
–
It may not alert everyone
although EH-100 is operating properly in your vehicle. People may not hear
the siren sound so you MUST continue driving cautiously. Frequently inspect
the speaker to ensure that it is clear of any obstruction, such as snow or mud.
Improper use of the speaker or of its installation will reduce the efficiency of
sound output, which results in degrading the alert effectiveness. Be also aware
that the use of EH-100 does not give you the right to force your way through
traffic. Your siren sound, the action is requesting the right-of-way only.
EH-100 is made up of two separated electronic devices with a cable
connected between them. The amplifier box contains all intelligence to
generate siren sound and PA amplification.
A current-sensing circuit protecting the amplifier from overload is built in.
Upon a short circuit/overload such as overheat inside the speaker, or improper
vibration of speaker diaphragm, is sensed, the amplifier will be disabled to
minimize possible damage of the amplifier. A regular fuse of 15 amperes is
also installed inside the amplifier to protect the siren system.
When the vehicle horn ring switch is operated, depending on the selection of
the externally accessible three-pin jumper’s position, the siren will produce
either Air Horn or Manual siren sound. With the power of the siren turned off,
the horn ring switch closure will perform the regular vehicle horn sound.
