Warnings and Notices for Users and Installers

WARNING: Take CAUTION when installing a siren system. Adequate hearing protection
for you and those within the immediate vicinity is mandatory since sirens emit extremely
loud warning tones. Loud noise can cause hearing damage and/or loss. Refer to OSHA
1910.95 prior to operating a siren unit for occupational noise exposure guidelines. .
This document must be delivered to and read by the end user and installer as it serves to
provide you with the required information for proper and safe use of your STL product. Before
operating this or any STL products the user and installer must read this manual all the way
through. You will find important information in this manual that could prevent property damage
and/or serious injury to the user and installer.
STL products are intended to alert pedestrians and other operators of the presence of
personnel, the operation of emergency vehicles, an emergency site, and any warning needs. This
does not ensure that pedestrians or drivers will react, heed, or observe emergency warning
signals. Nor does the use of emergency signals grant or ensure you the right of way. It is your
responsibility to make sure you can proceed safely before driving against traffic, entering an
intersection, responding to a high rate of speed, or walking on or around traffic lanes.
Your STL emergency vehicle devices should be tested daily to insure the device and all it's
functions are operating correctly. If you experience a malfunction contact STL's Customer
Service immediately for troubleshooting options, or a warranty or service claim. You must
ensure sure that the projection of the visual and audible is not blocked by vehicle components
(i.e.: open trunks, visors, compartment doors), vehicles, other obstructions, or people.
STL's sirens and other audible devices project sound in a forward direction and should be
installed in a forward direction that faces away from the occupants of the vehicle.
