Ring Communications DNA100 - Manual (Page 16)

April 2012 Digital Network Adapter DNA100
Additional Status For Master Display Line :
IDLE - Indicates no DNA100 activity present at the master station.
DIAL - Indicates the DNA100 sent a request to dial. It sends a request to dial when an attempt is made to
answer an incoming event.
WAIT - Indicates status change for master. No keyboard entries will be accepted during W
AIT
state. W
AIT
status occurs after the master cancels an event that was handled.
TALK - Master station is in conversation initiated by the DNA100. The DNA100 must be used to cancel the
conversation to remove the T
ALK
status from the display line.
Operation :
IDLE -
When there are no annunciations (A
LARMS
, F
AULTS
or C
ALLS
) to display, Q
UE
will display 00, the T
IME
will always be
visible and the event display lines will be off. The real-time status display will show all stations programmed to
report to this annunciator as O
K
unless F
AULTS
are present in the system. In I
DLE
mode the Intercom master
station assigned to the CRT will also be idle and may be used in normal intercom mode by using the dial pad on
that station. Unused slots on the screen are filled with ellipses (...dots....).
INCOMING EVENT -
When the CRT DISPLAY receives an event a display line will appear and an audible tone will be heard from the
terminal. There is room to display five events in the queue. The middle line will be highlighted as the current line
that can be activated. See H
ANDLING
M
ULTIPLE
I
NCOMING
A
NNUNCIATIONS
later in this chapter. The Q
UE
will show the
number of display lines in use. The user should always note the status of the event (A
LARM
, C
ALL
, F
AULT
, P
ARK
)
before responding since the incoming status of the line will not be apparent when answered. The event lines will
be placed in queue in the order they are received if they all have equal priority. When an event with greater
priority is received it is placed ahead of existing events with lower priority level. Priority (P
RI
) level is
programmable from 1 through 9, 1 being top priority (see N
ETWORK
C
ONFIGURATION
for programming).
HANDLING AN EVENT - The S
PACE
B
AR
Once the status has been observed, the current highlighted display line can be answered by pressing the S
PACE
BAR
on the CRT keyboard. When the S
PACE
B
AR
is pressed, the audible annunciation tone will stop, and the
DXC901 will connect the intercom master station at the CRT D
ISPLAY
with the substation that initiated the event. A
warning tone will sound at both stations, and you may begin speaking after the tone. The intercom will normally
switch your voice hands free, although it may be necessary to use the 'T' button on the intercom station for
simplex operation (push to talk) to overcome background noise at either location. The 'T' may also be used
whenever you want to continue monitoring a station for information or security reasons.
