The green AC On LED illuminates steadily as long as the main power is above minimum level. The
indicator turns off when the level falls below the minimum level and the panel switches to standby
(battery) power.
The red Common Alarm LED will illuminate steadily whenever there is a fire alarm. If the panel is set
for two stage operation, pressing the red General Alarm button will also turn on the Common Alarm
indicator. This indicator will remain on until the system is reset.
The amber Common Supervisory LED illuminates at the fast flash rate when there is a supervisory
alarm in the fire alarm system. For non-latching supervisory alarms, the Supervisory LED will turn
off when the condition causing the alarm goes away. For latching supervisory alarms, this LED
remains on until the panel is reset.
The amber Common Trouble LED flashes at the trouble flash rate when the panel detects any
trouble condition. For non-latching trouble conditions, the Common Trouble LED will turns off when
the condition causing the alarm goes away. For latching trouble conditions, this LED remains on
until the panel is reset.
The amber Remote Trouble LED flashes at the trouble flash rate if the panel detects a trouble at the
City Tie or UDACT module, communication trouble with a remote annunciator, or a local trouble at a
remote annunciator.
The amber Fire Drill LED illuminates steadily after the Fire Drill button is pressed. This LED remains
on until the Fire Drill button is pressed again.
If the panel is configured as a two-stage system, the amber Acknowledge LED flashes at the fast
flash rate while the Auto General Alarm timer is timing out. The Acknowledge indicator illuminates
steadily when the General Alarm timer is cancelled by the pressing of the Acknowledge or Signal
Silence buttons. If the Auto General Alarm timer times out and puts the panel into general alarm,
this LED turns off.
If the panel is configured as a two-stage system, the red General Alarm LED illuminates steadily
when the General Alarm button is pushed, a General Alarm Initiating circuit is activated, or the Auto
General Alarm timer times out. Once the General Alarm LED has turned on, it will stay active until
the panel is reset.
