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:
NOTE: For instructions on programming the Presignal function, refer to the NFS2-640
Programming Manual.
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 pro-
grammed outputs. A sample Alarm screen for a monitor module is shown below:
