3-2.5.7.1 What to Do When a Pre-Alarm Occurs
Press the <ACKNOWLEDGE> Key to change the Pre-Alarm LED from
flashing to steady illumination and to silence the internal buzzer. It will be
necessary to press the <ACKNOWLEDGE> Key more than once to change
the Pre-Alarm LED from flashing to steady illumination and to silence the
internal buzzer if multiple unacknowledged pre-alarm events are present.
All pre-alarm acknowledgments are logged.
The display changes to indicate the next unacknowledged pre-alarm event
in the case of multiple pre-alarm events.
The system will then continue pre-alarm-event annunciation. You may
manually scroll through the list of active and acknowledged pre-alarm-
initiating devices in order of occurrence by using the <SCROLL> Key. They
will be displayed using the format of Figure 3-23.
3-2.5.7.2 Pre-Alarm Silencing
Press the <SILENCE> Key to de-activate any silenceable outputs such as
control unit-based notification-appliance circuits and SLC-based signal or
relay modules after all pre-alarms have been acknowledged. Outputs are
made silenceable through the ARIES configuration program. The control
unit will display the following message for 5 to 10 seconds:
Figure 3-24. Outputs-Silenced Message
You may then manually scroll through the list of active and acknowledged
pre-alarm-initiating devices after the outputs silenced message in
Figure 3-24 is displayed.
The Silence LED will illuminate when the <SILENCE> Key is pressed after
all pre-alarm events have been acknowledged. A subsequent press of the
<SILENCE> Key will re-activate any outputs that were silenced if no new
pre-alarm events were reported. The Silence LED will also go out. This
toggling capability will remain in effect until the control unit is reset.
A silence command that caused all silenceable outputs to de-activate will
be overridden by a subsequent pre-alarm report. All silenced outputs
associated with the subsequent pre-alarm initiating device will reactivate,
and the Silence LED will go out. The <SILENCE> Key must be pressed
again to de-activate any active, silenceable outputs.
3-2.5.7.3 How to Reset the Control Unit After a Pre-Alarm Condition
The ARIES Control Unit resumes normal operations when it receives "Pre-
Alarm Off" messages from all previously-alarmed automatic initiating
devices unless one or more latching outputs such a control unit based
notification appliance circuit has been turned on. This mode of operation
ensues regardless of whether the automatic alarm-initiating devices are
configured for latching or non-latching operation.
Press the <RESET> switch to resume normal operations if latching outputs
have been activated.
