Simplex 4006-9121 - System Reset

Chapter 7. Operating
7-2
FIRE 1/2
The panel is a Global Acknowledge system meaning that
one press of an Acknowledge key acknowledges every
abnormal point in the system within that category. Pressing
the Ack key allows the operator to scroll through all the
abnormal points in that category. The additional information
listed below can be obtained by pressing the <ENTER> key.
• The electrical state of the point (open, short circuit, nor-
mal, abnormal)
• Enable/Disable state of the point
• Manual override state (if output)
• Assigned Alarm Groups
Silencing Alarms
The "Alarm Silence" key allows the operator to silence
active Notification Appliance Circuits that are programmed
for "on-til-silence" operation.
Caution: Pressing the Alarm Silence key causes fire alarm
evacuation signals to turn OFF. Follow local procedures to
silence alarm evacuation signals.
To silence an alarm, press the <ALARM SILENCE> key.
• All "on-til-silence" notification appliance circuits will
turn OFF
• The Alarm Silenced indicator LED turns on
If a subsequent alarm occurs, the notification appliance cir-
cuits resound.
System Reset
The <SYSTEM RESET> key restores the system to its nor-
mal state after an alarm condition has been cleared. When
the <SYSTEM RESET> key is pressed, it causes all latched
circuits to reset automatically. The system displays the
"RESET IN PROGRESS" message when the key is pressed.
After a short delay and if all alarms are cleared, the system is
restored to its normal, non-alarm state (e.g. all alarm notifi-
cation, relays, etc. are turned off). The alarm points are
removed from the alarm list and the alarm LED turns off.
If a device remains in alarm during the reset period, the sys-
tem reset is aborted, and the system remains in the alarm
state. The display continues to show the device(s) that
remain in alarm.
Viewing/Clearing Historical Logs
The panel has three separate, non-volatile historical logs:
Alarm, Supervisory, and Trouble. These logs can be viewed
separately, or they can be viewed in chronological order as a
single combined log. Each log records information about the
event and the time the event occurred. The following table
describes the different logs and their stored events.
