NOVEMBER 2005 DAD104DIGITAL ANNUNCIATOR DISPLAY

RING COMMUNICATIONS, INC.

PARK KEY - Used to place handled annunciations in the PARK 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 LINES are shown in . Note that spaces count as one character position.

The extension number always occupies the first four digits. The 0114 represents the annunciated

station’s EXTENSION number. The CAR 4 A is the location DESCRIPTION for extension 0114.

Each line has a STATUS. Before being handled the status is flashed alternately with the location

description. An incoming annunciation event can have a status of Alarm, CALL or FAULT. An example of

an incoming STATUS of a FAULT is shown on display line 3 of .

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 PARK.

BUSY - When another display location answers a DISPLAY 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 TALK 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).

For example: 0114 CAR 4 A BANK BUILDING #1
