Figure 4-27. PAS Acknowledgment Message
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 PAS status and display will be cleared if the smoke detector has reported an
Alarm clear and you press <SYSTEM RESET> or the PAS timer expires. A PAS de-activation event
is stored in the event log if an Alarm Off message is reported.
4-10.3.6 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. Refer to NFPA 72, National Fire Alarm
Code (latest edition) for details.
The Alarm Verification State occurs when the FenwalNET 8000-ML 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 FenwalNET 8000-ML Configuration Software.
Figure 4-28. Typical Alarm Verification Message Display
The following actions also occur when an alarm verification is reported:
• The internal buzzer pulses
• The alarm verification event is stored in the event log
• The alarm verification message is transmitted to peripheral devices (such as Remote Display
Control Modules and Remote LED Annunciator Modules), if applicable
• The alarm verification message is communicated via the RS-232 and USB ports
Note: For systems configured with Alarm Verification, the alarm-verification period must be a
minimum of 60 seconds for a UL-listed installation. ULC requires an alarm-verification
period not less than 30 seconds.
