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).
