Common Supervisory LED (PFC-5004 or PFC-5004E/PFC-5008 only)
The amber Common Supervisory LED illuminates steadily when there is a supervisory alarm in the panel resulting from any
latching or non-latching supervisory circuit. The LED turns off if all non-latching supervisory circuits are restored and there are
no active latching supervisory circuits. Latching supervisory alarms remain active until the panel is reset.
Common Trouble LED
The Common Trouble indicator fl ashes amber (at 20 fl ashes per minute) when the panel detects any trouble condition. It turns off
when all non-latching troubles are cleared.
Remote Trouble LED (PFC-5004 or PFC-5004E/PFC-5008 only)
The Remote Failure indicator illuminates amber if the panel detects trouble at a city tie or DACT module, or communication or
local trouble with a remote annunciator. It turns off once these conditions return to normal.
Fire Drill LED
The amber Fire Drill LED illuminates steadily while fi re drill is active.
Auxiliary Disconnect LED
The Auxiliary Disconnect Indicator fl ashes amber (20 fl ashes per minute) when the Auxiliary Disconnect switch is activated. It
turns off when the switch is activated a second time. When on, the Auxiliary Disconnect LED indicates that common alarm and
common supervisory relays, and any ARM-4 / ARM-8 relays are not activated. The trouble relay is activated. If installed, DACT
or polarity reversal and city tie modules are also inactive, causing a trouble condition.
