SECTION 3
TROUBLE CONDITIONS
INTRODUCTION
NOTE: Refer to Figure 3 for locations of interface panel LEDs and keys.
When a System Trouble Condition is detected by the 4100, the condition is indicated by the following:
• Yellow “SYSTEM TROUBLE” LED on the interface panel is flashing
• Tone-alert sounds steady
• Annunciator LEDs may be illuminated
• Alphanumeric display on the interface panel shows the following message.
The interface panel has a yellow SYSTEM TROUBLE LED which lights whenever a trouble is present in the system.
When a trouble occurs, the LED flashes, the tone-alert sounds steady, and a trouble message appears on the
alphanumeric display. The trouble LED glows steady and the tone-alert silences when the <TBL ACK> key is
pressed.
When Global Acknowledge is used, and the trouble clears, the system automatically clears without user intervention.
After approximately 30 seconds, the system alphanumeric display should indicate a normal system, as shown below.
When Individual Acknowledge is used, the tone-alert “re-sounds” when the condition clears. The <TBL 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 system alphanumeric display should indicate a normal system.
