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.
