Dual Lane System Installation; Figure 10. D-30 Connections - 3M C860 Installation Instructions Manual

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

Dual Lane System Installation

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.
