When the first alarm condition is detected by the 4100U-S1, the panel does the following to
indicate the presence of the alarm.
• Red Fire Alarm and common Zone Alarm LED indicators flash
• Red Zone Alarm LED flashes on the display module showing the affected zone.
• Sounder (buzzer) pulses
• Emergency Warning System (EWS) and External bell activate
• Alphanumeric display on the operator interface shows the location and type (smoke, call
point, etc.) of the point in the alarm condition. An example is shown in
Figure 2-1.
• Any programmed outputs, including the Brigade connection, operate.

The first step in managing an alarm condition is to acknowledge the alarm. Acknowledging
an alarm does two important things:
• It records the time and date at which you observed the presence of the alarm and stores
that information in the system’s historical log.
• If multiple alarms are present, the system displays specific data for the next alarm when
you press the <FIRE ALARM ACK> key.
