Operating Instructions 

          

Description 

 

The ACC-1004 and ACC-1004-TXLR3 are amplified extension 
speakers that are designed to provide more than 10 watts of audio 
output when connected to the INCX-4001 or INCX-4101 intercom 
stations.  These amplified speakers are useful for increasing audio 
output level in noisy locations. 
 
Both speakers use an integrated circuit amplifier to provide the 
necessary gain to raise the output audio level and a DC voltage 
power source of 10 to 16 volts at 1.5 amps is required to provide 
proper power for the units.  In the case of the ACC-1004 stripped and 
tinned DC power leads are provided with an in-line fuse holder 
containing a two amp fuse for short circuit or overload protection.  In 
the case of the ACC-1004-TXLR3 a power connector and an in-line 
fuse holder for use with the INCX-4101 are also provided.  Both units 
are protected from accidental reverse polarity of the power leads. 

 

INSTALLATION: 

 

1.  Locate the amplified speaker indoors or in an area free from 

direct exposure to weather. 

 
2.  Plug the audio connector into the matching connector inside the 

INCX-4001 (Note that this connector is labeled “AMPLIFIER”) or 
on the appropriate connector outside the INCX-4101 housing.

3.  Connect the power leads from the ACC-1004 to a 10 to 16 volts 

DC power supply capable of providing at least 2 amperes.  This 
same power supply  may be used to power the INCX-4001 
Intercom Station if desired.  The diagram below shows how to 
power the AC-1004 and INCX-4001 from the same supply. 

 
 

When using the INCX-4101 simply connect the power connector  

 

from a matching PS-1230US-TXLR3 into the appropriate 

 

connector on the outside of the INCX-4101. 

 
 

Note that a Liteway PS-1205 will not provide enough power for 

 

this application.  A  PS-1230US 3 Amp supply is required to 

 

power the INCX-4001 intercom stations and speaker while a PS-

 

1230US-TXLR3 is required to power the INCX-4101 and ACC-

 

1004-TXLR intercom station for proper operation.. 

 

IN EITHER CASE DO NOT APPLY MORE THAN 16 VOLTS DC OR 
 

 

 

DAMAGE TO THE UNIT MAY OCCUR.! 

 
4.  Audio will now come through the external speaker instead of the  

intercom station’s built in speaker.  The audio output volume is 
controlled by the front panel volume control of the INCX-4001 or 
INCX-4101 intercom station.
