DAD104 Digital Annunciator Display Module

The DAD104 Digital Annunciator Display Module is part of the Ring Crisis Alert System. This system provides for supervised lines from remote locations that are capable of being programmed to annunciate a twelve (12) character alphanumeric message and also show four (4) simultaneous call in the display at one time. All other calls are kept in queue and can be retrieved in any order, by scrolling up or down. The DAD104 will display the queue of calls in a priority order from any of the eight (8) programmable call-in levels. The DAD104 shall also provide a clock 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 contact closure to drive other external devices at other locations (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.
