messages in its memory. The DCPU port should be configured in the
DCPU Database as a “Display” port using the FCC Compiler program.
Annunciator Operation - Connected to LSS4 Panels
When connected to an LSS4 panel, the CMDN annunciator is defined
as device address #15. RSA4-CPUs used with point annunciators may
be with CMDN/SMDNs on the LSS4 RS-485 circuit as long as there
are no more than four remote annunciators total on the circuit. The
remote annunciator’s sub-addresses must not conflict. Refer to the
LSS4 section of the Configuration Program section for additional
details. Each CMDN-C/SMDN-C is optically isolated from the panel.
A Remote RS-485 Interface Card (P/N 130285) is required to connect
the remote annunciator circuit to the LSS4 panel on motherboard
revisions prior to 1.5.
User Operations
Overview
Each CMDN-C/SMDN-C recalls message information stored in its
internal memory in response to the zone information it receives from
the CM1N, CM2N, or DCPU. Each CMDN(-C)/SMDN-(C) is buffered
for 1,000 messages, and messages require local acknowledgment.
Visual Indicators
LCD Display:
The primary display is a back lit, super-twist Liquid Crystal Display
(LCD). This display provides four lines with twenty alpha-numeric
characters in each line. As a power saving measure, the back lighting is
activated by any change of state, off normal condition or front panel
switch activation. Time and date information is automatically updated
from the network controller.
Point address information is not
automatically displayed.
If this information is required, it must be
included as part of the text message. The LCD back lighting will turn
off after 4 minutes if there is no switch activity and no
unacknowledged messages are waiting.
Sample messages are shown below for annunciators connected to IRC-
3 or FCC networks:
