General Overview
The New Computer emergency desk system has been designed to replace the existing DAC desk or upgrade a standard rack system to provide an emergency desk. The system includes the hardware and software to provide an operator the ability to visualise and communicate with personnel underground using the existing DAC equipment.

Normal operation
In normal operation, the operator will be able to contact personnel underground by selecting the required extension from the mimic panel and sending a ring tone. The mimic panel will indicate which extensions are in use, or idle, and emergency calls.

Emergency Operation
In the case of an emergency, the mimic panel on the control room PC will indicate where the call originated and allow full duplex voice communications between all parties.

Voice Recording
Voice recording of operator calls is an option that allows automatic recording of all voice conversations; this can be configured to record automatically from the activation of an emergency call from a phone underground. Allowing the operator to record the details of the incident for later playback to other emergency personnel. This recorded data is further protected via a secure password to ensure data is not inadvertently lost or erased.

Emergency Procedure Questionnaire Prompting
When voice recording feature is fitted, the initiation of an emergency alarm, will automatically display a operator help screen, this gives a list of questions from the mines emergency procedures with questions as shown below:

The details are on screen and the recording feature provides the facility to replay the conversations later to fill in on details.

Manual Record Initiation
The recording function can be manually activated to allow the control room or emergency operator to record calls during busy periods or while away from the desk, useful for personnel on backshifts.

PABX Failure Mode
In the event of the PABX failure the operator then has the ability to override and take control of all underground communications via the PC. Underground
personnel will be able to communicate to the surface using the emergency button.

The Line Control Unit is a failsafe design; if a failure occurs, then outputs will be connected direct to the existing desk or rack, ensuring no loss of communications.

Visual Diagnostics
The mimic display shows the status of all phones connected. You can see which phones are in use. Provides a useful indication and is a valuable aid in troubleshooting the phone system ie if a cable is damaged.

Memo function, each telephone’s record has a facility to add notes regarding this phone, e.g. date of installation, reports from operators etc. This allows a history file to be put together.
