Use the PC Programmer’s List Tab to add the following to List L7 (Control
Points Off on Reset). Members of this list automatically turn off when a System
Reset is performed.
• Standard (non-QuickAlert) Visible NACs.
• Class B QuickAlert NACs.
• The Class A QuickAlert NACs wired to the “NAC IN” input of the SCM.
Note: Assign the Class A QuickAlert Horn Control NAC to List L6, as
described in “Step 3. Add Appropriate NACs to List L6 (Off on Silence)”
above.
Adding each floor’s initiating devices to a separate list limits the number of
Custom Control equations required to implement this application. To add a
floor’s initiating devices to a list, use the PC Programmer’s List Tab, adding
each floor’s initiating device to a separate user-defined list (L26 through L50).
For a multi-story facility containing a large number of NAC circuits, add each
floor’s NACs to a separate user-defined list. Doing this limits the number of
Custom Control equations required to implement this application. To add a
floor’s NACs to a list, use the PC Programmer’s List Tab, adding each floor’s
NACs to a separate user-defined list (L26 through L50).
This section describes programming the Selective Signaling by Fire Floor
application using either standard NAC appliances or Class A/Class B
QuickAlert NAC applicances. Refer to the applicable section below for specific
information.
Standard NAC Example. The following example, shown in Figure 2-7,
illustrates how to implement this application for a four-story building that uses
standard NAC appliances.
Each of the four equations functions in the same manner. The input side
monitors a list of initiating devices for the floor. If any point within the list goes
into ALARM, the output side activates the NACs for the appropriate set of
floors.
