Introduction
Description
The LSRA-C Alpha-Numeric display Annunciator features a 4-line,
20-character back-lit alphanumeric liquid crystal display for use with
the IRC-3 and FCC RS-485 data lines; FCC/DCPU printer ports; and
LSS4 series fire alarm panels. An optional RS-232 printer/download
port (LSRA-232) is available for the annunciators for either connection
to the host system or a local printer, depending on annunciator and host
system configuration. The printer provides a hard copy of the
information on the annunciator display. The annunciators require 24
VDC for operation.
All annunciator front panels include Normal, Alarm, Supervisory, and
Trouble LEDs. The LSRA reduced complement annunciator provides
only the NEXT/ACKNOWLEDGE and BACK switches. The LSRA-C
is a full complement annunciator, providing a password protected
enable/disable function for the, RESET, ALARM SILENCE,
TROUBLE SILENCE, DRILL/ALL CALL, NEXT/
ACKNOWLEDGE, and BACK switches. Figure Chapter 1-1 shows
these two configurations.
All configuration and message information is contained within each
annunciator's memory. Each annunciator is individually programmable
for the type of messages it displays, and is individually programmable
for which front panel switches are operable when the password is
entered. Each annunciator can be configured to display a combination
of Alarm, Supervisory, or Trouble messages.
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, then recalls and
displays the appropriate information for this zone.
