DAD104 Digital Annunciator Display Module

The DAD104 Digital Annunciator Display Module is part of the Ring Crisis Alert System. T his
system provides for supervised lines from remote locat ions that are capable of being
programmed t o annunciate a t welve (12) c haract er alphanumeric message and also show
four (4) simultaneous c all in t he display at one time. All ot her calls are kept in queue and
can be retrieved in any order, by sc rolling up or down. The DAD104 will display t he queue of
calls in a priority order from any of the eight (8) programmable c all-in levels. The DAD104
shall also provide a cloc k that will display military time (24 hour format) down to one
second. The DAD104 is designed to mount into the model BBF863 (flush) or BBS863
(surface) back box or BBD905 (desk adapter).

The DAD104 module provides a c ontac t closure t o drive other external devic es at other
locat ions (i.e. strobes, louder buzzers, etc .). The wiring is terminated on positive screw
terminals.

The DAD104 station is designed to work with the RM5000EX and/or CB901EX series
microprocessor intercom systems.
