Overview
How the FACP
Indicates the
Presence of a
Trouble
When a trouble condition is detected by the FACP, the panel does the following to indicate the pres-
ence of the trouble condition.
• Yellow LED, labeled "SYSTEM TROUBLE" flashes
• Tone-alert (piezo buzzer) sounds steady
• LEDs on remote annunciators may illuminate
•
The LCD on the interface panel indicates a trouble condition. The exact manner in which the
display reports information for the trouble condition depends on which system display is enable.
There are six ways that the Flexible User Interface can display a trouble condition. An example
is shown below. Refer to
Chapter 2
for descriptions of the six displays.

What an
Acknowledge Does
The first step in managing a trouble condition is to acknowledge the trouble. Acknowledging a
trouble does two important things:
• It records the time and date at which you observed the presence of the trouble and stores that
information in the system's historical log.
• When you press the acknowledge key, the system displays specific data on the location of the
trouble.
The FACP can be configured with either global or individual acknowledge. These options function
as follows:
• Global Acknowledge. When global acknowledge is enabled, one press of the
TROUBLE ACK key acknowledges every point currently reporting a trouble.
• Individual Acknowledge. If individual acknowledge is enabled, the TROUBLE ACK key
must be pressed to individually acknowledge each trouble. Individual acknowledge must be
selected if the panel is providing proprietary receiving service in accordance with NFPA 72.
The TROUBLE ACK key, which is used to acknowledge troubles (either globally or individually),
is located just beneath the SYSTEM TROUBLE LED. If the TROUBLE ACK key is passcode pro-
tected (by default, it is not), you cannot use this key to acknowledge troubles unless you log in
using the required passcode.
