G.2.2 Action Level Pre-Alarm Function
Action Level Functions
If a detector reaches a level that exceeds the programmed Action threshold, an Action
condition is indicated. The following functions are performed at Action level:
• The message is sent history file and to installed peripheral devices, such as the
LCD-80 and printer.
• The Pre-Alarm LED and panel sounder pulse until acknowledged.
• Zone 99 activates. No other zones or relays activate.
• The fifth zone programmed (not the first four) for this detector is activated. The
fifth zone is the right-most entry on line three of the point programming screen.
This zone may be used to control functions of a detector or group of detectors on
Action level. The fifth zone activations will also allow ACS annunciation by a
detector or group of detectors in Action Pre-Alarm state.
• The Pre-Alarm condition and the zone programmed latch until System Reset, even
if the sensitivity drops below the Action or Alert level.
• A subsequent alarm condition for this detector clears the Action indication from
the panel LCD display and Pre-Alarm LED, but will not reset the fifth zone (the
fifth zone is also on the alarm list).
Example of a Pre-Alarm Action Condition
Figure 154 shows a sample panel display that appears if a detector is in Action level. In
this example, zone 99 is programmed for Action = 60% of Alarm. Any measurement
that exceeds 1.20% (0.60 X 2.00%) causes an Action Pre-Alarm condition.

You can adjust the setting of the two Action and Alert levels (from 00% to 99%) to suit
your application. From the Special Zone Change screen (Figure 74 on page 87), select

PREALM is the
Pre-Alarm status banner.
2.0% is the
programmed alarm
threshold (2.0% per foot
obscuration is the low
sensitivity setting).
Action indicates that
the Action level is
reached.

is the type code
of the detector.
1.20 is the real-time approximate
obscuration reading.
