Communication and Signalling
Equipment
Austdac has designed a new
intelligent amplifier which is totally compatible and interchangeable
with the existing amplifier unit presently used in conveyors
and longwalls throughout NSW and Queensland.
The new amplifier
has been changed with full fault diagnostics and to improve
the general appearance and operation of the overall system.
The system design improvements which
can be displayed on the new LCD screen are as follows:
|
|
• Local
internal battery voltages level.
• Local battery charge current.
• Inbound and outbound PSA Tones to dictate cable
line faults and location.
• Easy menu driven displays.
• Durable membrane.
• Volume level setting (PSA & local override).
• Optional remote headset facility.
• Individual speaker fault indication "Left Speaker
Faulty" "Right Speaker Faulty".
• Noise cancelling microphone.
• Back lit LCD display.
• Better battery life (6 months battery life left
when battery is disconnected from the line).
• Lower charge current.
• Ingress protection IP66. |

Communication and Lockout Station
with Telephone keypad
This Communication and Lockout Station
can also be used in conjunction with a keypad to allow direct
dial facility from underground directly into the DAC I.S.
Telephone system.
The Communication and Lockout Station
can have a "remote isolation" facility (when used
with a Signal Line System) and an Interrogate Button to allow
the operator to access pre-recorded "Belt Stoppage"
messages.
