The upper line of the LCD display shows the time remaining to investigate
the PAS report before the PAS event transitions to an alarm condition. The
investigation time will continually decrease in one-second intervals. The
control unit will return to Normal Operation if you press the <RESET> Key
or the smoke detector reports an Alarm Off message at any time prior to
the expiration of the investigation period. A PAS de-activation event is
stored in the event log if an Alarm Off message is reported.
Alarm Verification
Alarm verification allows a fire-alarm system to delay generating an
evacuation signal when an alarm report is received from a smoke detector.
The fire-alarm system will wait for a second alarm report from the smoke
detector that issued the initial alarm report or another alarm signal from
any other alarm-initiating device before it generates the evacuation signal.
The fire-alarm system will resume normal operations if it does not receive
a second alarm report from the smoke detector or another alarm signal
within the user-defined alarm-verification period. See Chapter 6 of NFPA
72, National Fire Alarm Code, 2002 Edition for details. Refer to the ARIES
User's Programming Guide to configure a smoke detector for alarm
verification.
The Alarm Verification State occurs when the ARIES Control Unit receives
an emergency signal from a smoke detector configured for alarm
verification.
The upper line of the LCD display shows the event by the device address,
the change of state, and the device type. The lower line indicates the up-
to-40-character message assigned to the alarm-initiating device using the
ARIES configuration program.
