When a trouble condition is detected by the 4100, 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 alphanumeric display on the interface panel indicates trouble condition, as shown below
Figure 3-1. Interface Panel Showing Trouble Condition
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.
It is important to understand that the 4100 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 <TBL
ACK> key acknowledges every point currently reporting a trouble.
• Individual Acknowledge. If individual acknowledge is enabled, the <TBL 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 NFPA72.
The <TBL ACK> key, which is used to acknowledge troubles (either globally or individually), is
located just beneath the SYSTEM TROUBLE LED. Refer to Figure 3-1. If the <TBL ACK> key
is passcode protected (by default, it is not), you cannot use this key to acknowledge troubles
unless you have the required passcode.
