A yellow LED for each zone that blinks if the zone has been programmed for 
supervisory and a supervisory condition exists on the corresponding zone.  It turns on 
steady when the Acknowledge or Alarm Silence button is pressed.

A yellow LED for each zone that blinks to indicate that a trouble exists on the 
corresponding zone.  It turns on steady when the Acknowledge or Alarm Silence button 
is pressed.

A yellow LED for each zone that blinks to indicate that a I

 smoke detector on the 

corresponding zone is dirty or in need of maintenance.  It turns on steady when the 
Acknowledge or Alarm Silence button is pressed.

A yellow LED that blinks to indicate a ground fault condition on the system.  A ground 
fault occurs when zero impedance between the FACP and earth ground exists.  The 
LED turns on steady when the Acknowledge or Alarm Silence button is pressed.

Normal mode is the standard mode of operation.  In this mode, the panel continuously 
monitors system status.  When no alarm or trouble conditions exist, the control panel 
will be in the following state:

• all LEDs will be off (except the AC Power LED)

• the Notification Appliance Circuits will be off

• all relays are in their normal state

• the onboard piezo sounder will be off

• I3 smoke detectors will be polled for maintenance and freeze conditions on initial 

entry into Normal mode.  Thereafter, each device will be polled every hour for 
freeze and every four hours for maintenance conditions

All alarm and system trouble conditions are annunciated on the control panel’s LEDs.
