2.0 Bose ® FreeSpace ® Model 8 And Model 32 Loudspeakers

Bose designed the FreeSpace Model 8 and Model 32 loudspeakers to provide high fidelity voice and music reinforcement in commercial settings. These Virtually Invisible ® loudspeakers meet the aesthetic demands of most architectural designs. The loudspeaker rim and grille can be painted to match the setting.

Bose has an information sheet explaining how to paint the rim and grille.

Call 1-800-996-BOSE and ask for a copy of 183073 Loudspeaker Painting.

FreeSpace Model 8 loudspeakers are available in two versions: 100V (Europe and

Japan only) and 70V (North America only). FreeSpace Model 32 loudspeakers are available in three versions: 100V (Europe and Japan only), 70V (North America only) and 4 Ω (worldwide). All 70V and 100V versions require a Bose approved equalizer, such as the Bose FreeSpace (Model 8/32) system controller. Using the loudspeakers without an approved equalizer causes inferior acoustic performance and may damage the loudspeakers. The 4 Ω version of the Model 32 loudspeaker does not require an approved equalizer. It is compatible with the

FreeSpace BMA-125 business music amplifier and other amplifiers.

2.0 Bose ® FreeSpace ® 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.

3.0 Before You Begin

3.1

Ceiling type

Evaluate the ceiling construction BEFORE beginning installation. Ceiling type, thickness, and strength determine the installation and connection methods as well as the necessity of support rails. A qualified person, such as a building trade professional, architect, or licensed professional engineer, should make these determinations.

Bracket installation

This guide covers installation methods for both ceiling tile and structural ceilings.

Structural ceilings – Follow the instructions for structural ceilings.

Soft ceiling tiles – If the tiles are made of a “soft” material (like mineral wool or glass fiber), follow the instructions for ceiling tiles. This will provide extra support.

Rigid ceiling tiles – If the tiles are made of particle board, plywood, gypsum board or plaster, follow the instructions for ceiling tiles. Or, follow the instructions for structural ceilings. However, the tiles must be strong enough to support the loudspeaker without the help of the support rails. See “Support rails” below for more information.

Support rails

Not all ceilings require the use of the support rails. Only a qualified person, such as a building trade professional, architect, or licensed professional engineer, should determine if a ceiling alone is strong enough to support the loudspeakers.

Ceiling tiles – Use the support rails with any ceiling tile made of mineral wool, fiberglass, or other fibrous material. These tiles do not remain flat, may absorb moisture, and may not always support the loudspeaker’s weight.

The support rails are 23 3 /

4

" (603 mm) long and will support a loudspeaker in a 2' x 4' or smaller tile. If the ceiling tiles are another size, the support rails will usually provide adequate support if they meet the edge of the tile on at least two sides.

Follow these guidelines:

For 600 mm tiles, place the mounting pans and support rails at a 10

°

–15

°

angle

(Figure 2).

6

AM177915_03_V.pdf • May 6, 2002

3.0 Before You Begin

For 625 mm tiles, extend the rails in opposite directions until each rail reaches the ceiling grid on one side of the mounting pan.

Ceiling tiles made of particle board, plywood, gypsum board, or plaster usually do

Figure 2

10

°

– 15

° not require support rails. However the support rails may be needed if moisture or other environmental conditions may weaken the ceiling.

Structural ceilings – The support rails and spacers must be removed from the ceiling pans before using the structural ceiling installation method.

Rotation feature

FreeSpace ® Model 8 and Model 32 loudspeakers can be rotated on their springs to conveniently access the terminals after installation. The ceiling pan and springs hold the speaker in place while the tap settings are changed or electrical connections are completed (see Figures 21 and 22 on page 15). Be careful not to damage the mounting hole when turning or releasing the loudspeaker.

Do not use the rotation feature if the loudspeakers are installed in a very thick ceiling. In general, the rotation feature works with FreeSpace Model 8 loudspeakers installed in ceilings up to 2" thick, and with FreeSpace Model 32 loudspeakers installed in ceilings up to 1" thick. To be certain, install one loudspeaker and attempt rotation as described in Section 4.3, “Electrical connections.”

3.2

Clearance

Allow enough clearance for both the depth of the loudspeaker and the wire from the electrical fitting. To decrease this distance, use an angled electrical fitting with flexible metallic conduit or flexible metallic tubing.

3.0 Before You Begin

3.3

Preparing wires

70V and 100V versions

The loudspeaker terminals will accept either stripped wires or crimp-on forked connectors.

Note: Using forked connectors for multiple wires is not acceptable in fire protective signaling and warning systems due to the lack of electrical supervision capability.

Prepare the wires as shown (Figure 3).

• For bare wire connections, strip the wires to 3 /

8

" – 7 /

16

" (9 – 10 mm).

• For crimp-on connectors, strip the wires to 5 /

16

" (8 mm). Use only insulated barrel connectors. Uninsulated terminals can short circuit to the cover. Before crimping, make sure the wire is fully inserted into the connector with no uninsulated wire exposed.

4

version

Strip the wires to 5 /

16

" (8 mm).

Note: Stranded wire is preferred.

DO NOT solder (tin) the wires.

3.4

Junction box fittings

70V version

The junction box has a 7 /

8

" diameter hole.

Select and install a UL listed 1 /

2

" trade size wire fitting (Figure 4).

Note: To meet local electric codes, fittings for 3 /

8

" or 1 /

2

" flexible metallic tubing or flexible metallic conduit may have to be used.

100V version

Both a plastic strain relief bushing and a plastic bushing are supplied. Use whichever is appropriate.

4

Ω

version

A plastic bushing is already installed.

Note: If local code requires flexible metallic tubing or flexible metallic conduit, be sure it is well supported. Too much unsupported tubing or conduit can weigh the loudspeaker down, pushing it away from the ceiling surface.

versions)

All models are UL 1480 listed:

• Vandal resistant (with grilles in place);

• General use - UL Category UEAY, Control number 3N89, File number S5591;

• Air handling spaces (ceiling plenums) - NFPA 70 NEC 1993 Article 300-22

(C) and UL 2043; NFPA 90A-1993 Installation of air conditioning and ventilation systems, section 2-3.10.1 (a) exception 3.

FreeSpace Model 8 and Model 32 (70V fire safety models)

In addition to the above listings, fire safety models are UL listed for fire protective signaling.

• Fire protective signaling use - UL Category UUMW, Control number 42S9,

File number S 3241).

C.2 Fire protective signaling

Bose ® offers 70V fire safety models of both FreeSpace Model 8 and Model 32 loudspeakers listed with UL as fire protective signaling devices. These loudspeakers are available only by special order.

Signal processing equipment

The Bose FreeSpace ® (Model 8/32) system controller is the only equalizer listed for use with FreeSpace Model 8 and Model 32 loudspeakers in fire protective signaling and warning systems. The FreeSpace system controller installer’s guide describes the proper set up of fire protective signaling and warning systems using FreeSpace

Model 8 or Model 32 loudspeakers.

Wire preparation

Although the loudspeaker terminals will accept either stripped wires or crimp-on forked connectors, using forked connectors as shown in Figure 18b for multiple wires is not acceptable in fire protective signaling and warning systems due to the lack of electrical supervision capability. Electrical supervision capability is maintained by connecting each wire individually to the terminals.

Sound Pressure Level (SPL) specifications

Loudspeaker sound pressure level is measured per UL-1480/ANSI-S1.12/ANSI-

S1.2 in the specified reverberant chamber. These SPLs will differ from the specification given in the tables contained in Appendix A and Appendix B.

variable) with each doubling of input power.

Because our transformer gives slightly less than the required

3dB step between 8 watts and 16 watts, we must show the last dB rating. In this case, there are two 90dB ratings. For these values, the actual UL measured level for the

8W tap is 89.9dBA, for the 16W tap is

92.5dBA, and for the
