Installation — Stage Three, cont’d

N

The installation must conform to national and

local electrical codes, and UL requirements.

Refer to the device’s user manual for details.

1. Cut ceiling tile

If installing FF 120 speakers, do the following:
a.

Remove the ceiling tiles where the speakers are to be

installed.

T

For ease of working on the speaker when it is replaced

on the T-frame, remove an adjacent tile(s).

b.

Mark a line 12 inches from one of the short sides of the

tile and cut along the line. Discard the short portion.

T

Use a fine hacksaw blade to cut the tile without

damaging the face and place an empty box under the
tile for support and to collect the waste.

2. Install the speaker on the drop ceiling

a.

At the speaker location, lay one of the supplied T-rails

12 inches from one end of the T-frame. The speaker will

be placed into the small section.

b.

Remove the terminal cover from the rear of a speaker

and attach the anchor ring and cable clamp to the cover.

c.

Place the speaker onto the T-frame and, passing the

speaker cable through the cable clamp, connect the

speaker wires to the speaker terminals:

• Red wire - positive (+)

• Black wire - negative (-)

d.

Reattach the terminal cover.

e.

If possible, bend the seismic tabs over the T-rails.

f.

Replace the ceiling tile.

Repeat the steps 1 and 2 for each speaker that needs to be

installed, connecting the speakers according to the system

preferred (e.g., in parallel, see page 2-18).
If you wish to install an optional seismic/safety cable, at

each speaker location do the following:

g.

Mark, drill and install a lag eye bolt for the seismic/

safety cables (not included) in the structural ceiling

above the speaker location.

h.

Pass the seismic cable through the anchor ring down

to the seismic tab and twist the end around the cable 5

times. Pass the other end up through the lag eye bolt

and twist that end around the cable 5 times.
