Installation Guide for Optional Plaster Ring
An optional plaster (mud) ring bracket is available from TANNOY. This bracket is designed to be pre-installed 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 fi tted and complete the plastering work on the ceiling. (Fig.2)
3. Go to the 'Wiring and Setting Up' chapter, then return to point 4 below.
4. 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 fi rm 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.3)
DO NOT OVERTIGHTEN!
5. Attach the nylon safety to the hooks on the front baffl e before attaching the grille by presenting it to the speakers
and allowing the magnets to pull it into position (Fig.4). (With the CMS 403DCe/ICTe, the grille is already fi tted to
the product.)
NOTE ON INSTALLATION OF CMS 403DCe/ICTe:
Before tightening the screws in step 4, swivel the speaker in the desired direction. When the screws are tightened, the speaker will lock into position. Replace the front
trim to conceal the mounting screws.
