Description of Major Components

The Driller's Intercom stations consist of a factory-sealed enclosure (top) and a termination enclosure
(bottom). Refer to Figure 1 for details. The factory-sealed configuration eliminates the need for external
seals on this unit; however, additional seals may be required on auxiliary devices.
The audio, control, and power components for this assembly are contained in the factory-sealed
enclosure. The front panel of the factory-sealed enclosure contains the user interface components
(microphone, status LED, and keypad [digital models only]).
All system terminations (power, speaker, system, footswitch, and beacon) are to be made in the
termination enclosure.
This station requires an external speaker (sold separately) to operate. Also, a customer-supplied beacon
(digital models only) and footswitch can be added to this unit for visual status indication and talk/listen
control.
CAUTION
Use only suitably listed components for the hazardous area.
