If you use a D–30 as the auxiliary intercom, a separate monitor speaker must 
be provided for the Model C1060.  (Both the Model C1060 and D–30 
intercoms require separate monitor speakers.) 

 

 

A dual lane system consists of two separate single lane systems that operate independently of each other.  Each 
single lane system has its own dedicated base station and headset(s). 

To install a dual lane system: 

1.  Install two single lane systems as outlined in these installation instructions. 

Base station models C921 and earlier must be mounted at least 25 feet apart.  
Base station models C922 may be mounted as close as 2 feet apart. 

 

2.  With the base stations turned off, set jumper J3 on one of the base stations so that it jumpers pins 1 and 2.  

This designates the base station as a lane 1 system. 

3.  Set jumper J3 on the other base station so that it jumpers pins 2 and 3.  This designates the base station as a 

lane 2 system. 

 

Do not set both base stations to the same lane number as this will cause 
operational problems. 

  

4.  Turn on both base stations and press the RESET SWITCH on each of the base station circuit boards to “read” 

the jumper setting into the microprocessor.
