remain. Once the MW’s are acknowledged, they are removed from the
active point buffer.
Note: With the LSRA(-C) in the auto-acknowledge mode, the printer
functions are not available.
Internal Buzzer Silence
The LSRA’s internal buzzer sounds when there are any un-
acknowledged trouble conditions that are not silenced. In the internal
buzzer silence mode, the buzzer can be completely disabled for silent
operation in areas sensitive to high noise.
With the buzzer disabled, the following conditions can be expected.
When the IRC/FCC/LSS system reports a TROUBLE or
SUPERVISORY condition, the trouble silence LED will light,
reporting that the buzzer is silenced. The trouble silence LED will also
stay illuminated after the final message is acknowledged. When the
system reports an ALARM, the buzzer will not sound and the trouble
silence LED will not light even after the final message is
acknowledged.
Note: Refer to the installation section for proper dip switch setup for
enabling auto-acknowledge or disabling the internal buzzer.
