Silence Reset
Use this button to silence an alarm for 60 seconds, to reset an alarm, to start a 60 second preemptive
silence period, and to permanently silence the Vent Inop and Standby alarms. Two important
definitions for understanding how the Silence Reset button works:
Active alarm: An alarm for which the condition currently exists.
Inactive alarm: An alarm that has occurred, but for which the condition no longer
exists.
Silencing and Clearing Alarms:
To silence an active alarm for 60 seconds:
1) Push the Silence Reset button. The audible alarm will be silenced for 60 seconds. Once the
silence period expires, the audible alarm will resume sounding.
To clear an inactive alarm:
1) Push the Silence Reset button. The visual alarm displays will be cleared.
To cancel an active alarm:
1) Push the Silence Reset button twice. The audible alarm will be silenced and the visual alarm
displays will be cleared and the silence period will be terminated.
Preemptive Silence Period
To start a preemptive silence period:
1) Push the Silence Reset button. A 60 second silence period will begin. For any alarms that occur
during the silence period, the visual displays will flash, but the audible alarm will remain silenced
until the end of the silence period.
Vent Inop and Standby alarms:
To silence the Vent Inop or Standby alarm:
1) Push the Silence Reset button. The audible alarm will be permanently silenced, but the Vent
Inop LED will remain lit for a minimum of 5 minutes. This does not adversely affect battery life.
