Figure 2-2. Selective Signaling by Floor, Standard NACs
QuickAlert Class A / Class B NAC Example. The following example,
shown in Figure 2-3, illustrates how to implement Selective Signaling by Floor
using Class A or Class B QuickAlert 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 Floor 1. The output side of Equation 1 programs the floor'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 this equation monitors the FIRE DETECT
state of list L27, which is a user-defined list containing all initiating devices
for Floor 2. The output side of Equation 2 programs the floor's QuickAlert
NACs to operate when any point within list L27 enters an ALARM
condition.
Important Note: Use HOLD ON for Class A QuickAlert devices; use
HOLD TEMPORAL for Class B QuickAlert devices.
•
Equation 3. The input side of Equation 3 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 P26 to its OFF state.
Important Notes:
- The HORN OFF opcode is used for Class B QuickAlert applications.
This equation is not required for Class A QuickAlert applications.
- Resetting P26 is very important; do not leave this out.
