Model 8 And Model 32 Loudspeakers

All versions meet all regulatory standards for ceiling loudspeakers and are UL

listed as vandal resistant. A 70V fire safety version of each model, available only

by special order, is also UL listed as a fire protective signaling device. Complete

safety agency listings and special requirements for fire protective signaling and

warning systems are contained in Appendix C, "Safety Requirements."

For seismic security, the loudspeaker enclosures and mounting pans have holes

for attaching security wires. Used with appropriate hardware, these attachment

points may qualify the loudspeakers as earthquake resistant. Check local building

codes.

In North American loudspeaker installations, both UL and CSA permit the use of

Class 2 wire (CL2, CL2P, or CL2R) for loudspeaker wire. If the wire passes through

a plenum, only CL2P is acceptable. Since most commercial ceiling spaces are

used as plenums, most installations will require CL2P. In risers such as vertical air

handling ducts or any through passage from floor to floor, CL2R is classified for

this use. To maintain compliance with plenum installations, use metallic electrical

connectors.

See Table 725-53 of the National Electric Code (NEC) for a list of acceptable wire

substitutes.

It is recommended that the fire marshall or building inspector be consulted before

installing these loudspeakers in air handling spaces (plenums) because some

areas require the use of metallic conduit or metallic tubing.

2.1 Unpacking the loudspeakers

Unpack the loudspeakers carefully (Figure 1). Save the carton and all packing

materials.

If any part appears damaged, do not install the loudspeakers. Repack them and

immediately notify Bose Service or your authorized Bose Professional Products

dealer.

For the most efficient installation, review this section and plan ahead before wiring

and installing Bose FreeSpace Model 8 or Model 32 loudspeakers.
