Design Guide Supplement: Safety Cables
Before attempting installation, please read all instructions
& warnings in the installation guides for the product
& the safety cable.
Introduction
This document provides important information to system designers about the use of safety cables with certain Bose
loudspeakers in commercial cooking environments.
Bose has discovered that the mounting components on some of our loudspeakers can degrade and break when exposed
to certain substances. If the mounting components break, the loudspeaker could fall and result in personal injury or
property damage. Lubricants and cooking oil are the only substances to which the affected loudspeakers are likely to be
exposed at levels high enough to degrade their mounting components. Therefore, lubricants should never be used during
installation and loudspeakers that will be exposed to cooking oils must be installed with a safety cable.
Affected Products
All variants of the products listed here as well
as mounting accessories (such as pendant-
mount kits) are affected.
Flush-mount (In-ceiling) Models:
Surface-mount Models:
EdgeMax EM90
FreeSpace DS 16S / 16SE
EdgeMax EM180
FreeSpace DS 40SE
FreeSpace DS 16F
FreeSpace DS 100SE
FreeSpace DS 40F
FreeSpace DS 100F
FreeSpace 3 Flush-Mount Satellites
FreeSpace 3 Series II Acoustimass module
Applications
The loudspeaker requires a safety cable if it meets either of these conditions:
A
It is installed in the same room as a cooking surface. This means that the loudspeaker and cooking surface are not
separated by
(1)
full-height walls,
(2)
full-height doors, or
(3)
wall openings that are normally closed.
B
It is a flush-mount (in-ceiling) loudspeaker and is exposed to air from a room with a cooking surface via an HVAC
system with an above-ceiling plenum return. An
HVAC system
provides heating and cooling services to a building.
An
above-ceiling plenum return
is a separate space between the structural ceiling and a drop-down ceiling that
allows for air circulation for the HVAC system.
In the diagram above, the installed Bose loudspeakers are circled and numbered:

2
The surface-mount in this dining area does
not
require a safety cable.
3
The flush-mount loudspeaker in this kitchen requires a safety cable.
4
The surface-mount loudspeaker in this kitchen requires a safety cable.
