5 Trouble conditions
5.1 Introduction
A trouble condition indicates that a circuit or system function is in an abnormal condition. Trouble conditions are not fire conditions;
however, they must be addressed by a capable service technician. Failure to correct trouble conditions may compromise the detection and
report of an emergency condition.
This section describes using the operator interface panel keys to investigate the details of the trouble condition.
5.2 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 presence 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 enabled. There are six ways that InfoAlarm can display a trouble condition. An
example is shown below. Refer to
for descriptions of the six displays.

5.3 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 protected (by default, it is not), you cannot use this key to acknowledge troubles unless you log in
using the required passcode.
