Ground Fault LED:
The Ground Fault Indicator flashes amber at the Trouble Rate when the Ground Fault Detector detects a Ground Fault on any field
wiring. It is turned off when the Ground Fault is cleared. The GND FAULT is a yellow (amber) LED which illuminates whenever
a ground fault is present on the system. Pushing the INFO button will give further information as the location of the ground fault
(i.e. negative side of loop 1, etc.).
Alarm Queue LED:
The Common Alarm Indicator turns on steady red whenever the Panel is in Alarm as a result of an alarm on any Initiating Circuit
or activation of the manual red General Alarm Button (if the Panel is set for Two-Stage Operation). Since all Alarms are latched
until the Panel is reset, the Indicator will remain on until then.
Supervisory Queue LED:
The Common Supervisory Indicator turns on steady yellow (amber) when there is a Supervisory Condition in the Panel, as the result
of any Latching or Non-Latching Supervisory Circuit. The Indicator is turned off if all Non-Latching Supervisory Circuits are restored
and there are no Latching Supervisory Circuits active. Latching Supervisory Conditions remain active until the Panel is reset.
Trouble Queue LED:
The Common Trouble Indicator flashes yellow (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.
Monitor Queue LED:
The Monitor Trouble Indicator flashes yellow (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.
Fire Drill LED:
The Fire Drill Indicator turns on steady yellow (amber) while Fire Drill is active.
Signal Silence LED:
The Signal Silence indicator flashes yellow (amber) at the trouble rate when Notification 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.
LED Indicators may be Yellow (amber), Red, or Green, and will illuminate continuously (steady), or at one of two Flash Rates
based on the type of signal
Fast Flash
- 120 flashes per minute, 50% duty cycle
Trouble Flash - 20 flashes per minute, 50% duty cycle
A Trouble condition indicates that there is a fault in the system. Failure to investigate and mitigate a Trouble condition could
render part or all of the system inoperable.
