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.
•
Door Holder Relays.
•
Standard (non-QuickAlert) Visible NACs.
•
Class B QuickAlert NACs.
•
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.
This section illustrates how to implement Selective Bypass of NAC/Relay
Circuits for a facility that uses either standard NACs or Class A and Class B
QuickAlert NACs. Refer to the appropriate section below.
Standard NACs. The first two input statements, separated by the AND
operator, check whether there is an activated initiating device and whether the
bypass switch (monitored by pseudo P76) is active. The NACs activate when
the following conditions are both true, and do not activate if either is false.
•
List L26 contains an activated initiating device (i.e., a smoke detector in
alarm).
•
P76 is NOT in its ON/CODING state (i.e., the NACs activate if the switch
is not active).
Figure 2-9. Selective Bypass of NACs, Standard NAC Example
QuickAlert NACs. Figure 2-10 shows how to implement the selective bypass
application with Class A or Class B QuickAlert NACs. As with the Standard
NACs example, the first two input statements check whether there is an
activated initiating device and whether the bypass switch (monitored by pseudo
P76) is active.
The NACs activate when the following conditions are both true, and do not
activate if either is false. Use HOLD TEMPORAL for Class B QuickAlert
NACs; use HOLD ON for Class A QuickAlert NACs.
•
List L26 contains an activated initiating device (i.e., a smoke detector in
alarm).
•
P76 is NOT in its ON/CODING state (i.e., the NACs activate if the switch
is not active).
