Safety
Warning!
Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of suspending objects
overhead. Bosch strongly recommends all loudspeakers be suspended taking into account all
current national, federal, state, and local laws and regulations. It is the responsibility of the
installer to ensure all loudspeakers are safely installed in accordance with all such
requirements. When loudspeakers are suspended, Bosch strongly recommends the system be
inspected at least once per year or as laws and regulations require. If any sign of weakness or
damage is detected, remedial action should be taken immediately. The user is responsible for
making sure the wall, ceiling, or structure is capable of supporting all objects suspended
overhead. Any hardware used to suspend a loudspeaker not associated with Bosch is the
responsibility of others.
Caution!
The seismic tab (auxiliary support ring) is not intended for primary suspension of the
loudspeaker. The seismic tab should only be used as a secondary safety point.
Caution!
When using the weatherized terminal cover, the original auxiliary support ring is no longer
used. Attach the safety cable to the auxiliary support ring on the weatherized terminal cover.
1.1
Caution!
Ceiling mount speaker’s safety cable
The safety cable should be installed with a minimum of 3-inches (76.2 mm) of slack.
Notices
Old electrical and electronic appliances
Electrical or electronic devices that are no longer serviceable must be collected separately and
sent for environmentally compatible recycling (in accordance with the European Waste
Electrical and Electronic Equipment Directive).
To dispose of old electrical or electronic devices, you should use the return and collection
systems put in place in the country concerned.

Introduction
Premium Ceiling Speakers from Bosch use innovative design and materials to provide high
performance in a flush-mount ceiling format. The rear input cover for EN54 is used to create a
seal to protect the ceiling speaker from moisture and foreign particles, if properly installed.
The weatherized terminal cover must be used in all EN54 installations. Two models comprise
the family: LC20-PC60G6-6E and LC20-PC60G6-8E.
Read through this manual to familiarize yourself with the safety information, features, and
applications before you use these products.
