Fire Drill LED
The amber Fire Drill Indicator illuminates steadily while Fire Drill is active.

If the Panel is configured as a two-stage system, the Acknowledge Indicator flashes amber at the Fast Flash Rate
while the Auto General Alarm Timer is timing out. The Acknowledge Indicator steadily illuminates when the Alarm
Timer is cancelled by the activation of the Acknowledge or Signal Silence buttons. If the Auto General Alarm Timer
times out and puts the Panel into General Alarm, the Indicator turns off.

Alarm Indicator has been turned on it will stay active until the panel is reset.
