OPERATOR MANUAL
SECTION 3 - FAULT CONDITIONS
When a fault condition is detected by the 4120 FIP, the condition is indicated on the main
4120 Interface Panel as follows:
• Yellow "SYSTEM FAULT" LED is flashing.
• Tone-alert is on steady.
• Alphanumeric display shows the following:
**FAULT **
ALARMS = 0
The panel has a yellow fault LED which will light whenever a fault is present in the system.
When a fault occurs, the LED will flash, the tone-alert sounds steady, and a fault message
will be displayed on the alphanumeric display. The fault LED will glow steady and the
tone-alert silences when the <FAULT ACK> key is pressed.
When Global Acknowledge is used and the fault clears, the system automatically clears
without user intervention.
"SYSTEM IS NORMAL" followed by time and date.

When Individual Acknowledge is used, the tone-alert "re-sounds" when the fault clears. The
<FAULT ACK> key must be pressed twice (once to change from Alarm Summary to actual
point, and once to acknowledge the condition). After a delay, the alphanumeric display
should indicate a normal system.
