Safety Notices

Some regional construction codes require the use of a secondary method of securing loudspeakers in the ceiling to provide security of a backup support. A secondary support line should be attached from the safety loop on the rear of the product to a source point on the ceiling. For PI models, the secondary support line should be attached from the back of the driver chassis to a source point on the ceiling. Please consult the relevant construction codes in your region.
When using a power driver to install the product, it is essential to use the correct torque level settings to avoid over-tightening and damage to the ceiling material or clamps. Recommended torque setting: 1.5 Nm
Tannoy will not be held responsible for any damages caused by the improper installation of these loudspeakers.
The CMS 603 ICT LS is UL-1480, category UUMW, for use with non-DC supervised systems.
Electrical Safety Notice: To comply with the standard UL-1480, metal-clad flexible conduit (BX) is required for connection to the terminal block for proper earth grounding.
In order to comply with UL regulations, the PI back can must always be used with the CMS PI models.

SAFETY NOTE:
In order to comply with the relevant fire safety regulations (ie. BS 5839:1998), it is required that in the event of fire, that failure of the circuit to which the loudspeaker is connected does not occur before evacuation of the building is complete. Suitable measures include: – a) use of terminal blocks (for connection to primary) with a melting point of not less than 650°C, for example constructed from ceramic materials; b) use of terminal blocks of a lower melting point but protected with thermal insulation;c) use of terminal blocks such that, on melting, an open-circuit or a short-circuit does not occur.

- Next, secure the wings of the pre-mount ring to a safe and secure fixing point by using suitable fixings. (Fig.4)
  
  Please turn over
Attach the conduit to the installed backcan. This can be done in two ways:
- METHOD 1 : You can use the clamp at the back of the pre-install backcan. The product will accept a squeeze connector with a thread size of up to 22 mm: To remove the cable clamp, simply unscrew the threaded washer (under the wiring cover) which holds the cable clamp in place and replace it with a conduit squeeze connector. (Fig.5)
- METHOD 2: You can use any of the three knock-out points at the sides of the PI backcan (19 mm, 22 mm or 28 mm diameter). (Fig.6)
If conduit is not chosen as the wiring method, run an approved speaker cable to the installed can.
Terminate in the top mounted cable clamp or with an approved cable connector in one of the three knock-out points at the sides of the PI backcan.
Cut hole in the proper location in the ceiling using a pad saw. Place the pre-install backcan over the hole. (Fig.7)
Go to the ‘Wiring and Setting Up’ chapter, then return to point 6 below.
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.8)

DO NOT OVERTIGHTEN!
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. (Fig.9)

Wiring and Setting Up

Open the wiring cover (if applicable) and locate the Euro-type connector plug and socket at the back of the speaker. (Fig.1)
For connection to an amplifier, use Pins 1 and 2 (Fig.2):
- Pin 1 is positive
- Pin 2 is negative
  For connection to additional speakers in a distributed line, Pins 3 and 4 are in parallel where:
- Pin 3 is negative
- Pin 4 is positive
Close the wiring cover and tighten both screws on the cable clamp (if applicable).
Use the rotary switch on the front of the unit to select low impedance (LoZ) mode or high impedance (70 V or 100 V) for distributed applications.
THE SPEAKER IS SUPPLIED IN LOW IMPEDANCE MODE. NEVER CONNECT THE SPEAKER TO A 70/100 VOLT AMPLIFIER WHILE IT IS SET FOR LOW IMPEDANCE.
CMS 403DCe/ICTe and CMS 503DC/ICT models (all variants) use a 30 W transformer. In distributed line applications, the transformer can be tapped at 30 W, 15 W and 7.5 W, with an additional 3.75 W tap for 70 V line systems. (Fig.3)

CMS 603DC/ICT and CMS 803DC models (all variants) use a 60 W transformer. In distributed line applications, the transformer can be tapped at 60 W, 30 W and 15 W, with an additional 7.5 W tap for 70 V line systems. (Fig.4)

Painting

If desired, the grille and baffle panel may be painted to match the surrounding décor.

Painting the baffle:

Carefully mask off the driver assembly using the paint mask provided to ensure that the paint does not come into contact with the cone and roll surround.
Apply several thin coats of paint – this will provide a better finish than one overly thick coat.
Painting the grille:
Carefully remove the acoustically transparent grille cloth from the reverse side of the grille.
Paint the grille and then replace the grille cloth – several thin coats of paint will provide a better finish than one overly thick coat.
Re-bond the grille cloth to the grille over the entire area using a light spray-adhesive to avoid audible resonances.
