Failure to follow all safety precautions and instructions may result in proper-
ty damage, serious injury, or death to you or others.
SAFETY MESSAGE TO INSTALLERS
People’s lives depend on your safe installation of our products. It is important to
follow all instructions shipped with the products. This device is to be installed by a
trained electrician who is thoroughly familiar with the National Electric Code and will
follow the NEC guidelines as well as local codes.
The selection of the mounting location for the device, its controls and routing of
the wiring is to be accomplished under the direction of the Facilities Engineer and the
Safety Engineer. In addition, listed below are some other important safety instructions
and precautions you should follow:
• Readandunderstandallinstructionsbeforeinstallingoroperatingthis
equipment.
• Thisunitmustbeinstalledbyaqualiedelectricianinaccordancewith
all National and local Electrical and Fire Codes, under the direction of
the authority having jurisdiction.
• Donotconnectthisunittothesystemwhenpowerison.
• Alleffectivewarningspeakersproduceloudsoundswhichmaycause,in
certainsituations,permanenthearingloss.Youshouldtakeappropriate
precautions such as wearing hearing protection.
• Afterinstallation,testthesoundsystemtoensureproperoperation.
• Alleffectivewarningspeakersproduceloudsounds,whichmaycause,
in certain situations, permanent hearing loss. The device should be
installed far enough away from potential listeners to limit their exposure
whilestillmaintainingitseffectiveness.TheOSHACodeofFederalReg-
ulations 1910.95 Noise Standard provides guidelines which may be used
regarding permissible noise exposure levels.
• ShowtheseinstructionstoyourSafetyEngineerandthenlethemin
a safe place and refer to them when maintaining and/or reinstalling the
unit.
• Afterinstallationandcompletionofinitialsystemtest,aprogramof
periodictestingofthisdevicemustbeestablished.RefertoNFPA72G,
