Programming
Directs the CM1(N) or PCPU to issue a system wide alarm silence
command. Operating the ALARM SILENCE switch generates a
trouble LED in the display and activates the internal trouble buzzer.
Pressing the ALARM SILENCE and TROUBLE SILENCE switches
simultaneously starts a 15 second LED test sequence.
TROUBLE SILENCE SWITCH
Silences the
local
annunciator's LSRA-C trouble buzzer after all
messages have been acknowledged. This is not a network-wide
function.
DRILL SWITCH
Directs the CM1(N) or PCPU to issue a system-wide drill command.
USER PASSWORD
Entering the annunciator enables or disables any combination of the
front panel RESET, ALARM SILENCE, TROUBLE SILENCE, and
DRILL switches.
Audible Indicators
The LSRA(-C) will pulse its internal buzzer when there are
unacknowledged messages in its message buffer. Trouble conditions
cause the buzzer to sound continuously, until silenced. The LSRA(-C)
(without a trouble silence switch) buzzer sounds
only
for
unacknowledged messages in its message buffer.
Auto-Acknowledge/Internal Buzzer Silence
Auto-Acknowledge
The auto-acknowledge mode automatically acknowledges messages
waiting without operator intervention. In auto-acknowledge operation,
the LSRA(-C) will display activated that have not restored.
In auto-acknowledge mode, when the FCC/IRC/LSS system sees a
TROUBLE, SUPERVISORY, or ALARM condition, the MW
(message waiting) counter will display the total number of messages
waiting to be acknowledged. If desired, the operator can manually
acknowledge each of message waiting. Once the system returns to a
normal condition, the messages in the LSRA(-C) will be automatically
acknowledged.
The messages waiting will acknowledge in the order in which they
came in. ALARM messages, because of their priority, will always be
first to be acknowledged. Should non-alarm events restore before the
ALARM conditions, the LSRA(-C) will not auto-acknowledge any
MW’s until the ALARM conditions are either manually acknowledged
or restored. If the operator acknowledges any of the TROUBLE,
SUPERVISORY, or ALARM conditions, and the system returns to a
normal condition, the LSRA will automatically acknowledge the
restored conditions. Any messages that have not been restored will
