3. INSTALLATION

The metal firedome provided with each loudspeaker offers quick installation into ceilings.

WARNING: Make sure that the loudspeaker is installed in a stable and secure

way in order to avoid any conditions that may be dangerous for persons or structures:

• Check to make sure that the ceiling has the necessary mechanical characteristics to

support the weight of the loudspeaker without the danger of it falling.

• Before suspending the loudspeaker, carefully check all the components to be used to

make sure there is no damage, deformation, corrosion and/or missing or damaged

parts that could reduce the safety of the installation.

Installation precautions

• Use speaker cables with an adequate cross-section (gauge). The greater the distance

between the amplifier and loudspeaker, the larger the connection cable cross-section

should be.

• To prevent inductive phenomena causing humming or distortion, the speaker cables

should not be run together with electrical energy conductors, microphone cables,

or line-level audio lines. Use speaker cables that have markings to distinguish the

polarity, such as insulation or conductors of different colors.

Installation procedure

1. Cut a hole in the ceiling, using all safety precautions to avoid cutting power lines,

water lines etc. Use the following table as a guide:

Loudspeaker

Diameter

CIS50

160 mm

CIS65

200 mm

CIS80

230 mm

2. Take the firedome, loosen the two wing bolts,

and slide the fixing plates upwards. This allows

the firedome to be pushed up inside the ceiling

hole. Before you do that, thread your audio

speaker cable through one of the firedome

grommets . The firedome comes with a large

fixing bolt for securing in case of earthquakes etc.

3. When the firedome is securely pushed up inside

the ceiling hole, slide the fixing plates down to

grip the top surface of the ceiling, and tighten up

the two wing bolts. This will hold the firedome in

place.
