1. Supervisory LED - The yellow Supervisory LED, when ON, indicates that

a zone programmed as Fire/Supervisory is in the current-limited state – not

an alarm condition. To display the zone in the supervisory state, press the

“ACK” key and view the zone number with decimal point on the red,

seven-segment display.

2. Alarm Silenced LED - The yellow alarm-silenced LED indicates that the

On Until Silenced notification appliances are OFF and that an alarm remains

in the system.

3. AC Power LED - The green AC power LED indicates AC power is applied

to the panel.

4. Fire Alarm Zone Display - The “FIRE ALARM ZONE” is a red, seven-

segment display that is used to indicate alarms and supervisories. If a single

zone is in alarm, the seven-segment display indicates the number of the zone

in alarm. If two or more zones are in alarm at any time, the display slowly

scrolls through the list of zones in alarm. The order of display follows the

order in which the alarms were received. The decimal point indicates the

start or end of an alarm list. Each alarm is displayed for two seconds. IDCs

with a fire alarm condition are illuminated on the red fire alarm display (‘1’

through ‘8’). IDCs in a supervisory condition are illuminated on the display

with a dot (‘1.’ through ‘8.’). The “ACK” key must be used to view

supervisory conditions when the yellow Supervisory LED is illuminated.
