4FA021301

 

GENERAL CHARACTERISTICS

Audio inputs with CINCH connectors (3,4).
Internal Mono/Stereo switch (12)
Built-in 60 VA supply source, supplying 16 V DC with electronic fi lter  
for general supply of the system (terminal 2).   
Mains input voltage: 230V AC (50/60 Hz) P3271
                              115V AC (50/60 Hz) P3272
Electronic protection against short-circuits and overloads in the 
supply. 
Telecontrol (with selector switch 7 in REMOTE position).  When any 
of  the system controls are activated, socket (5) automatically 
connects  supplying 220V to the sound source.  When all the controls 
of the system are switched off this socket disconnects 
automatically, switching off the sound source, with the subsequent 
energy saving.
Local control (with selector switch 7 in LOCAL position). To switch on 
the outer sound source manually, regardless of the state of the system 
controls.
Two-pin power switch (6) to totally disconnect the system.  
LED indicating operation of the unit (9).
Incorpora un fusible de protección de la entrada de red y base telecon-
trolada, y una protección de la salida de alimentación en baja tensión 
para la instalación (además de la protección electrónica). 
Rejilla aireacion con ventilador interno bajo ruido y con conexión 
automática 
All the components used for connection to the mains are offi cially

NOTE: It is advisable for the cables of the electricity supply mains 
to be as far away as possible from the unit circuit.

The connection to the distribution line can be done with wires, P9910 ó 
P9940 (in the case of paging or intercom) for the supply and the music 
channels.  The other wires can be used if required for any of the auxiliary 
functions.

  16- 

Audio output - Channel 1 Right - 3 V RMS max.

 R- 

Auxiliary terminal for telecontrol.

CONNECTION TO MAINS:

 

Insert the mains and the earth wires into the 

terminal strip (11) (to the right of the mains switch), through the holes 
situated on the rear circuit protector of the unit, and tighten the screws 
of the strip.  Make sure they are well-tight and that no wire thread is 
outside the holes.

CONNECTION TO THE SOUND LINE:

 

Connect the wires of the sound 

line to the strip (10), passing the wires through the groove of the circuit 
protector, with care not to mistake the order.  Make sure the screws are 
tightened correctly.

CONNECTION TO THE SOUND EQUIPMENT:

 

Connect the mains plug 

to the telecontrolled mains socket (5).  Connect the audio output of the 
equipment to the CINCH connectors (3,4) on the front of the unit.  To do 
this use a stereo connection wire (not supplied with the unit) with CINCH 
connectors on one end and with the connectors used in the music 
equipment.

NOTE: Terminal R permits the remote operation of the telecontrol.  It is 
used when two or more units are installed together.  By interconnecting 
their R terminals, if the telecontrol of one of the units trips that of the other 
trips at the same time.

The main unit will be installed in a P9002 flush-mount box or in a P9026 
surface-mount box, preferably next to the sound source.

The connection to the 220/230V mains will be done with at least 1 
sq.mm. section wires and double insulation. For safety reasons the earth 
connection must also be connected. 

 

IMPORTANT NOTE: Before connecting this unit to the 

 

 

electricity supply mains, the power switch of that system 

must be disconnected to make sure the connection is made with 
the correct safety guarantees.  Under no circumstances must the 
unit be handled outside its flush box, connected to the alternating 
current network. Make sure that you have made the earth 
connection correctly
