Overview

All annunciator front panels include Normal, Alarm, Supervisory, and
Trouble LEDs. The CMDN and SMDN reduced complement
annunciators provide only the Next/Acknowledge and Back Switches.
The CMDN-C/SMDN-C are full complement annunciators, providing
an Enable/Disable key switch, Reset, Alarm Silence with LED, Trouble
Silence with LED, Drill/All Call with LED, Next/Acknowledge, and
Back switches. The following figures show all available
configurations.
During operation, the host system transmits zone and change of state
information to all annunciators on the network. Upon receipt of a
change of state, each annunciator looks in its database, recalls and
displays the appropriate information for this zone.
Connection to IRC-3 and FCC/PCPU RS-485 Data Lines
For IRC-3 and FCC/PCPU data line applications, up to 352 messages
can be stored in each annunciator. The IRC-3 configuration is used
when configuring annunciators for use on FCC/PCPU RS-485 data
lines. Every 88 messages, or fraction thereof, requires 1 panel address,
with 4 panel addresses required for the maximum of 352 messages.
When configuring an annunciator for use on FCC/PCPU RS-485 data
lines, follow the IRC-3 sections of this manual. When connected to
network RS-485 data lines, the annunciator may be configured for
regenerative networking and Class A (Style 7) operation.
