2. Cut out the hole in the ceiling using a pad saw
following the broken line indicated on the
template. Slide the C-ring into the ceiling,
aligning it over the cut-out hole. (Fig. 2)
3. Follow steps 4 through 6 in section 4 above.
6 Installation of Optional
Plaster Ring
The optional plaster (mud) ring is designed
for pre-installation into newly constructed,
non-suspended ceilings.
1. Nail or screw the plaster ring to the joists.
(Fig. 1)
2. Lay the speaker wiring to where the speaker
will be fitted. Complete the plastering work on
the ceiling.
3. Follow steps 4 through 6 in Section 4 above.
4. Go to Section 7 following for instructions on
wiring and set-up instructions.
5. Slide the speaker assembly through the hole.
Turn the screws (denoted “Screw Fix”) clockwise
on the front of the speaker to extend the
mounting wings. Tighten the screws until a firm
grip is achieved.(NOTE: Screws have a PoziDriv
head; use of a PoziDriv driver is recommended).
If using a power driver, Tannoy recommends a
torque setting of 1.5 Nm. (Fig.2)
DO NOT OVERTIGHTEN!
6. Attach the nylon safety to the hooks on the front
baffle before attaching the grille by presenting it
to the speakers and allowing the magnets to pull
it into position. (With the CMS 403DCe, replace
the front trim to conceal mounting screws.)
NOTE ON INSTALLATION OF CMS 403DCe:
Before tightening the screws in step 5, swivel the
speaker in the desired direction. When the screws
are tightened, the speaker will lock into position.
