4-10.3.6.1 What to Do When Alarm Verification Occurs
Press the <SYSTEM ACKNOWLEDGE> Key to silence the internal buzzer. The display will change
appearance. Acknowledgments of alarm verifications are logged.
Figure 4-29. Alarm Verification Acknowledgment Message
The upper line of the LCD display shows the verification time remaining to receive an alarm
confirmation signal from the smoke detector. The verification time will continually decrease in one-
second intervals. The control unit will return to Normal Mode if the smoke detector does not
reconfirm the alarm condition or if no other alarm-initiating device reports at any time prior to the
expiration of the verification period. A verification off event is stored in the event log if neither an
alarm reconfirmation nor a secondary-alarm message is reported.
4-10.4 Supervisory State
The FenwalNET 8000-ML control unit enters the Supervisory State when an initiating event occurs
such as a monitor module report of a low-air-pressure condition in a pre-action-sprinkler system. It
also occurs when any SLC-based initiating or control device, or any control unit based output circuit,
is isolated.
The upper line of the LCD display shows the supervisory event by the device address, the state
change, and the device type. The lower line indicates the up-to-40-character message assigned to the
supervisory device using the FenwalNET 8000-ML Configuration Software.
Figure 4-30. Typical Supervisory Message Display
The following actions also occur when any supervisory condition is reported:
• The Supervisory LED flashes
• The internal buzzer pulses
• The supervisory event is stored in the event log
• The supervisory message is transmitted to peripheral devices (such as Remote Display Control
Modules and Remote LED Annunciator Modules), if applicable
• The supervisory message is communicated via the RS-232 ports
• Point- or group-specific and general supervisory outputs will activate, including previously-
silenced outputs.
