Indicators, Controls, and Operation
8.1 Common Indicators
8.1.1 Buzzer
The buzzer is activated by any of the following:
• Fire alarm: steady
• Supervisory alarm: fast flash rate
• Trouble: trouble flash rate
If the buzzer turns on in response to a non-latching trouble or supervisory, it will turn off if the
condition causing it to sound goes away and there is no other reason for it to be on.
8.1.2 AC ON LED
The green AC ON LED illuminates steadily while the main AC power is within acceptable
levels. It turns off when the level falls below the power-fail threshold and the panel switches to
standby (battery) power.
8.1.3 Common Alarm LED
The red Common Alarm LED illuminates steadily 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. Since
all alarms are latched until the panel is reset, the LED will remain on until then.
8.1.4 Common Supervisory LED
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.
8.1.5 Common Trouble LED
The Common Trouble LED flashes amber at the trouble flash rate when the panel detects any
trouble condition. It turns off when all non-latching troubles are cleared.
8.1.6 Remote Failure LED
The Remote Failure LED flashes amber at the trouble flash rate if the panel detects:
• Trouble at the city tie, or
• Trouble at the UDACT, or
• Communication trouble with a remote annunciator, or
• Local trouble with a remote annunciator.
It turns off once these conditions return to normal.
8.1.7 Fire Drill LED
The amber Fire Drill LED illuminates steadily while the fire drill is active.
8.1.8 Automatic Alarm Signal Cancel LED (Acknowledge)
If the panel is configured as two stage, the Automatic Alarm Signal Cancel LED illuminates
steadily when the timer is cancelled by activating the Automatic Alarm Signal Cancel or Signal
Silence buttons. If the Auto General Alarm timer times out and puts the panel into General
Alarm, the LED turns off.
