SETTING MCA AUDIBLE ALARM CUTOFF RESET TIME PERIOD
An audible alarm device is located on the MCA Control Panel. This alarm sounds when
any alarm condition monitored by the MCA occurs. The alarm can be manually silenced
(cut off) by pressing a local key. A local indicator illuminates when the audible alarm has
been cut off. The alarm remains silenced for the current alarm condition only. If another
alarm condition occurs, the audible alarm again sounds.
A programmable audible alarm cutoff reset feature is provided. Once an audible alarm
has been cut off, it automatically resets (and sounds if the alarm condition is still present)
after the time period programmed expires. If another alarm condition occurs, the audible
alarm again sounds.
The MCA Audible Alarm Cutoff Reset feature is active when an "AUDIBLE SILENT TIME
= mm MINUTES" value is selected.
The MCA Audible Alarm Cutoff Reset feature is inactive when "AUDIBLE ALARMS STAY
