The Buzzer is activated by any of the following
Fire Alarm - Steady
Supervisory Alarm - Fast Rate
Trouble - Trouble Rate
Monitor - Configurable to sound at Trouble Rate
If the Buzzer is turned on in response to a Non-Latching Trouble or Supervisory, it
will be turned off if the condition causing it goes away and there is no other reason
for it to be on.
The AC On Indicator is activated steady green while the main AC power is within
acceptable levels. It is turned off when the level falls below the power-fail threshold
and the panel is switched to standby (battery) power.
The Common Alarm LED flashes red whenever the Panel is in Alarm. An alarm
results from any alarm on any point or input programmed as Alarm or activation of
the manual red General Alarm Button (if the Panel is set for Two Stage Operation).
The Alarm Queue LED will go steady, once all alarms in the queue have been
reviewed using the Alarm Queue button. Since all Alarms are latched until the Panel
is reset, the Common Alarm LED will remain on until then.
The Common Supv. (Supervisory) LED flashes amber at the Fast Flash Rate when
there is a Supervisory Alarm in the Panel, as the result of any Latching or Non-
Latching Supervisory Circuit. The LED turns off if all Non-Latching Supervisory
Circuits are restored and there are no Latching Supervisory Circuits active. The
Supv. Queue LED will go steady, once all supervisory alarms in the supervisory
queue have been reviewed using the Supv. Queue button. Latching Supervisory
Alarms remain active until the Panel is reset.
The Common Trouble LED flashes amber at the Trouble Flash Rate when there is
any Trouble condition being detected on the panel. It is turned off when all Non-
Latching Troubles are cleared. The Trouble Queue LED will go steady, once all
troubles in the trouble queue have been reviewed using the Trouble Queue button.
The Monitor Trouble Indicator flashes amber at the Trouble Flash Rate when there is
any Monitor condition being detected on the panel. It is turned off when all Monitors
are cleared.
The CPU Fault Indicator is flashed yellow at the Trouble Flash Rate if the CPU is
faulty.
The Fire Drill Indicator turns on steady amber while Fire Drill is active.
If the Panel is configured as Two Stage, the Acknowledge Indicator flashes amber at
the Fast Flash Rate while the Auto General Alarm Timer is timing out. It turns on
steady amber when that Timer is cancelled by activating the Acknowledge or Signal
Silence buttons. If the Auto General Alarm Timer times-out and puts the Panel into
General Alarm, the Indicator is turned off.
In Two Stage Operation only, the General Alarm Indicator is activated steady red
when General Alarm is activated due to the red General Alarm button being pushed,
a General Alarm Initiating Circuit being activated, or the Auto General Alarm Timer
timing out. Once the General Alarm Indicator has been turned on it will stay active
until the Panel is reset.
The Signal Silence indicator is flashed amber, at the trouble rate when Indication
Circuits are Silenced either by the Signal Silence button, or by the Auto Signal
Silence Timer. It is turned off when the Signals are re-sounded by a subsequent
Alarm.
The Ground Fault Indicator flashes amber at the Trouble Rate when the Ground
Fault Detector detects a Ground Fault on any field wiring. It turns off immediately
when the Ground Fault is cleared.
