Silencing Alarms; System Reset; Historical Logs - Simplex 4008-9101 Installation, Programming And Operating Instructions

Chapter 8. Operating
The 4008 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 will turn on
If a subsequent alarm occurs, the notification appliance cir-
cuits resound.

System Reset

The <SYSTEM RESET> key is used to attempt to restore
the system to its normal state after an alarm condition has
been cleared. When the <SYSTEM RESET> key is pressed,
it causes all latched circuits to reset automatically. The sys-
tem will display 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 notification, relays, etc. are turned off).
The alarm points are removed from the alarm list and the
alarm LED will turn 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 will continue to show the device(s) that
remain in alarm.

Historical Logs

The 4008 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.
