This application monitors initiating devices and does the following:
• Automatic Initiating Device Activation. Sounds a pre-alert, slow
march time tone when an automatic initiating device (for example, a smoke
or heat sensor) activates. This tone lasts for five minutes. After five
minutes, if no Alarm Silence has occurred, the tone converts to a temporal
“general evacuation” tone. The purpose of this is to alert system operators
that an automatic initiating device has triggered and allow them up to five
minutes to investigate the cause of the alarm.
• Pull Station Activation. Sounds a temporal “general evacuation” tone,
for a duration of five minutes, when a pull station activates.
Note: Always consult the local AHJ to determine whether this type of
operation is allowed or not allowed.
The NACs used with the Pre-Signal application can be either the NACs located
on the panel’s SFIO board or the NACs located on a 4009 IDNet NAC extender.
Note: Class A QuickAlert cannot be used with pre-signal applications.
Use the PC Programmer to program the NACs with the device types and point
types listed in Table 4-1. When defining custom labels, make sure to use
descriptive labels, such as “FLOOR1-VISUAL-CIRCUIT.”
If necessary, refer to Chapter 7, Programming Points, of the 4010 PC
Programmer Installation and Programming Instructions (574-187) for
information on editing a point’s device type, point type, and custom label.

Option Explanation
SIGA
Use for Class A NAC. This type of NAC
contains multiple signal paths, allowing
circuit operation to continue if a single open
circuit occurs. This option requires
installation of a Class A NAC adapter card.
