The second output statement in Equation 2 programs the visible NACs to flash
when any point within L27 enters an ALARM condition. Because the visible
NACs were added to the Control Points – Off on Reset list (Step 4 above), they
stop flashing when a System Reset occurs.
Figure 2-5. Selective Signaling by Area, Standard NACs
QuickAlert Class A/Class B NAC Example. The following example,
shown in Figure 2-6, illustrates how to implement Selective Signaling by Area
for a building that uses QuickAlert notification appliances. Only a single area is
shown in the example. To program selective NAC control for additional areas,
copy these equations, substituting another area's initiating devices and NAC
appliances.
•
Equation 1. The input side of this equation monitors the FIRE DETECT
state of list L26, which is a user-defined list containing all initiating devices
for Area 1.
The output side of Equation 1 programs the Area's QuickAlert NACs to
operate when any point within list L26 enters an ALARM condition.
Important Note: Use HOLD ON for Class A QuickAlert applications;
use HOLD TEMPORAL for Class B QuickAlert applications.
•
Equation 2. The input side of Equation 2 monitors the ON state of P26,
which is the Alarm Silence Activated system pseudo point.
The first output statement in this equation turns the QuickAlert horns OFF
(using the Horn OFF opcode) when P26 is ON (i.e., following an Alarm
Silence).
The second output statement in this equation resets the P26 pseudo point to
its OFF state.
Note: Resetting P26 is very important; do not leave this out.
