Acknowledging Alarms

What the System
Does When an
Alarm Occurs
Overview –
Acknowledging
Alarms
When the first alarm condition is detected by the 4100ES, 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 to show 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 first point in the alarm condition, and also the most recent alarm, if there
are several. An example display 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.
