DAD104 DIGITAL ANNUNCIATOR DISPLAY
INTRODUCTION
The Digital Annunciator Display (DAD104) provides annunciation of A LARMS , C ALLS and F AULTS for
programmed, supervised stations. Handling is accomplished by single keystrokes. Four 12-character
alpha-numeric D
ISPLAY L INES clearly indicate the annunciated extension numbers and location
description. An audible tone accompanied by the flashing display line alerts the operator to annunciated
events in queue. Auxiliary change over contacts are available to control external audible alarms or
indicator lights which will activate anytime the internal tone is active. Additional annunciations beyond
the view of the four display lines are indicated by the Q
UEUE
C
OUNTER
. The U
P
/ D
OWN
scroll buttons are
used to maneuver the additional annunciations when more than four are in the queue into the display
area for handling. The current time of day is displayed in 24 hour format showing hours:minutes:seconds
(HH:MM:SS) in the time window.
It’s compact size allows for wall or console mounting. The face-plate dimensions match those of the
Ring-Master AA905C, 10" high by 5.5" wide, permitting use of the BBF or BBS863 back box if necessary
behind each unit for a uniform fit and look.
Power to the DAD104 can be supplied from the CB901 central exchange or a remote regulated 24
VDC power supply.
DAD104 operates on Ring Communications’ Crisis Alert System together with the DXC901 and the
DNA100. Refer to the N
