NOVEMBER 2001 DIGITAL ANNUNCIATOR DISPLAY DAD104
D6 RING COMMUNICATIONS INC.
PARK KEY - Used to place handled annunciations in the P ARK state for further handling by the
same or a different display location.
SPARE KEY - Used for Remote Control. This key will send an event to the DXC and the DXC will
send DTMF number 5 to the connected intercom station. If the connected intercom station is
equipped with a DTMF decoder and a relay (AN912RR) then the relay can be used to control a
remote function such as door-unlock.
EXPLANATION OF THE DISPLAY LINE
An example of the four D ISPLAY L INES are shown in Figure D1. Note that spaces count as one
character position. The extension number always occupies the first four digits. The 0114 represents
the annunciated station's E
XTENSION number. The CAR 4 A is the location D ESCRIPTION for
extension 0114.
Each line has a S TATUS . Before being handled the status is flashed alternately with the location
description. An incoming annunciation event can have a status of Alarm, C ALL or F AULT . An example
of an incoming S TATUS of a F AULT is shown on display line 3 of Figure D1.
CALL - Status when a call is initiated by a substation.
ALARM - Status for an alarm annunciation triggered by an alarm input from a sub/master
station.
FAULT - Status when a station or it's cable is defective, also if a loss of power occurs to the
station.
PARK - Status when a station is put on hold. After an incoming call is handled, it may be
placed in P ARK .
BUSY - When another display location answers a D ISPLAY line.
PWRFAIL - Power failure in a device (CB901 lost power and is running on batteries).
ACKNOWL - Non voice event has been acknowledged by a DAD104 (such as PWRFAIL )
Once answered by the DAD104, the display line shows only the annunciated station's EXTENSION
number and DESCRIPTION steady and is in the T
ALK state. When another display location answers
a DISPLAY line all other displays show BUSY for that line.
If the system also has a printer or CRT node, a more detailed description may be possible (up to
30 characters not including the four digit extension number).
