OPERATOR CONSOLE SYSTEM

CAPACITY : Can accommodate 20 / 40 /60 stations in the field OPERATOR ALERT : when the field station presses FS switch, the operator

gets an indication identifying the particular calling field

station.

OTHER FEATURES : A. Selective individual paging of field station fromconsole.

: B. All call emergency announcement to all field stations

from console.

: C. Conference facility enabling multiple field station to

Converse when needed.

ALERT TONES : Alert tones for selective individual paging & all call paging. CONSOLE OPERATION: With handset and tactile keypad suitable for industrial

environment.

System Inter-connection

Cables :

The system requires the following types of cables.

a). Signal cable: 6 core, 0.5 sq. mm ATC over all pvsc sheathed

armoured cable for audio signal inter-connection.

b). Power supply cable: 3 core, 1.5 sq. mm ATC overall pvc sheathed

armoured cable for power supply connection.

c). Loudspeaker Cable: 2 core 0.75 sq.mm ATC overall pvc sheathed

armoured cable for inter-connecting the paging unit with theloudspeaker.

All the signal cables are connected in radial format i.e., a 6 core, 0.5 sq. mm

ATC armoured cable from each field call station is terminated directly to the

main Junction box in the Control Room. The junction box provided at the

central exchange Main junction box - has necessary terminals for

connecting a pair of page lines, a pair of private lines and a pair of FS lines.

System Operation:

1). Field call station to Master Control Station:

When a field person wishes to talk to the Operator, he lifts the handset of

the FCS and presses the FS switch.

An audio beep and a blinking LED attracts the attention of the MCS

Operator. The numeric ID of the calling FCS is also displayed in the LCDdisplay in the MCS.

If more than one FCS is calling the attention of the MCS operator, all the

numeric IDs of the calling FCS are displayed in the LCD display.

Simultaneously an audio beep and a blinking LED is also present.

The MCS operator determines the priority by which the FCS are to be

contacted. Accordingly he selects the particular top priority FCS from the

calling FCS units.

The operator converses with the selected FCS in private Mode.

Once the call with the FCS is over, the MCS operator selects the next FCS on

priority

3). Field call station to Field call station:

If required, the inter-connection of the FCSs can be modified so that an FCS

in a particular group/zone can call on page mode the FCSs within the

group/zone and converse with them in private mode.

The basic operation of page announcements and private conversation

within the zone can be done by all the stations in the zone. Whenever a

page announcement is made by one member of a zone, it is heard in all thespeakers of the other stations in the zone. The wanted person in the zone

can go to the nearest field station and talk in private mode.

The private conversation now taking place can be heard by any other field

station operator in the zone and can take part in the private conversation, if

necessary. The existence of private conversation can be seen by theglowing private LED in all the field stations irrespective of whether a

particular field station operator is taking part in private conversation or not.

4). Additional functions by MCS operator:

a). The MCS operator can call a particular group or a combination group or

all the group and make a page announcement or any other announcement

as required. An alert tone precedes all paging announcements from the

console
