Alarm Levels
ALERT: When lit this LED indicates that the smoke
level is above the alert threshold. This means the
detector has identified very early stages of a fire
condition and/or that the smoke level in the area is
above normal.
ACTION: When lit this LED indicates that the detected
smoke level has passed the threshold value fixed for
Action, but is not intended to initiate a general fire alarm
response procedure.
FIRE 1: When lit this LED indicates that the detected
smoke level is above the threshold value set to initiate
a general fire alarm response procedure. This
indicates a fire may be imminent or is in progress.
When interfaced with a Fire Alarm Control Panel
(FACP) it can generate an automatic fire alarm.
FIRE 2: When lit this LED indicates a fire is in progress. The detector can be
interfaced with an FACP to activate automatic suppression systems and
evacuation procedures.

increase in the detected level of smoke, relative to the preset fire alarm level.
