Application
Overview
Model LSRA, with a minimum complement of control switches, is
designed for annunciation only applications. Model LSRA-C, with a
full complement of control switches, is designed for applications
requiring network annunciation
and control at remote locations. Upon
receipt of a host system change of state, each annunciator looks in its
database for information associated with this zone. Each annunciator is
programmed for the type(s) of messages it displays, such as alarm,
trouble, messages, etc. Annunciators are individually programmed for
which front panel switches are operable when the controls are enabled
by entering a password or activating an optional remote enable/disable
key switch. The LSRA(-C) annunciators can be connected to IRC-3,
FCC, and LSS4 systems. A description of each configuration follows.
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. A LSRA-323 option card is required to
operate the PT1-S printer.
