A.5.3 How to View Presignal and PAS Selections
You can use the Read Status Entry option to view the current selection for the Presignal function.
To do so, press the keys in sequence:
The LCD display shows the current selections for the Presignal function. The figure below shows a
sample LCD display of a Presignal function selected for PAS and a Presignal Delay Timer of 60
seconds:

A.5.4 How to Respond to an Alarm with Presignal Delay Timer (no PAS)
If an alarm occurs with a Presignal Delay Timer (60-180 seconds), the control panel displays the
type of device and the SLC address of the device causing the alarm. If a second alarm occurs during
the Presignal Delay Timer, the control panel aborts the Presignal Delay Timer and activates all
programmed outputs. A sample Alarm screen for a monitor module is shown below:
Figure A.9 Sample Alarm Display Screen
The FIRE ALARM LED flashes and the panel sounder pulses a steady tone. The control panel latches
until the alarm is corrected and you press the S
YSTEM RESET key to reset the control panel. You
have the duration of the Presignal Delay Timer (60-180 seconds) to respond to the alarm before the
control panel automatically activates all outputs programmed to F0. You can take the following
actions:
• To silence the panel sounder and change the FIRE ALARM LED from flashing to steady, press
the
ACKNOWLEDGE/SCROLL DISPLAY key.
• To abort the Presignal Delay Timer, press the SYSTEM RESET key.
• To manually activate all outputs programmed to F0, press the DRILL key. The Manual Evacuate
screen appears, the panel sounder pulses and the
FIRE ALARM LED changes from flashing to
steady. The Manual Evacuate screen and Alarm screen display alternately at 3-second
intervals.
If the Presignal Delay Timer reaches its programmed value, without operator intervention, the
control panel activates all outputs programmed to F0.
NOTE: For instructions on programming the Presignal function, refer to the NFS-320
Programming Manual.
