NOVEMBER 2001 DIGITAL ANNUNCIATOR DISPLAY DAD104 DAD104 DIGITAL ANNUNCIATOR DISPLAY INTRODUCTION The Digital Annunciator Display (DAD104) provides annunciation of ALARMS, CALLS and FAULTS for programmed, supervised stations. Handling is accomplished by single keystrokes. Four 12character alpha-numeric DISPLAY LINES 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.
NOVEMBER 2001 DIGITAL ANNUNCIATOR DISPLAY DAD104 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.
NOVEMBER 2001 DIGITAL ANNUNCIATOR DISPLAY DAD104 OPERATIONAL FUNCTIONS IDLE When there are no events to display, the QUEUE will display 00. The TIME will always be visible and the display lines will be off. In D I LE mode the Intercom master station assigned to the DAD104 will also be idle and may be used in normal intercom mode. See TRIDEX operation information supplied with central exchange.
NOVEMBER 2001 DIGITAL ANNUNCIATOR DISPLAY DAD104 PRIORITY OVERRIDE The master station at the DAD104 should be programmed with the "Priority override" privilege by SVT through the CB901's processor card. If a busy or privacy signal is encountered, you may then press the '0' key on the intercom to override the signal and obtain voice contact before the intercom times out (default is 15 seconds).
NOVEMBER 2001 DIGITAL ANNUNCIATOR DISPLAY DAD104 SILENCING THE AUDIBLE ANNUNCIATOR TONE When an incoming annunciation is received and cannot be handled immediately, the tone can be temporarily silenced by pressing the CANCEL key. If any additional activity occurs, the audible tone will sound again. The audible tone will also sound if another event is received while you are presently handling one.
