C.3.3 Action Level
Action Functions
If you program a detector for Action Pre-Alarm and the detector reaches a level that exceeds the
programmed Pre-Alarm level, the control panel indicates an Action condition. Indication at the
panel is the same as in Figure C.6 above. The control panel does the following functions when a
detector reaches the programmed pre-alarm level:
• The Action message is sent to the History buffer and to any installed FDU-80s and printers.
The message is sent (and time stamped) only at the time that it first occurred. This historical
data could provide valuable information about the progress of a fire.
• The
• Zone F09 is activated—but Zone Z00 (general alarm or any other zone) and the System
Trouble and System Alarm relays do not activate.
• The fifth zone programmed (not the first four) for this detector activates. The fifth zone is
the right-most entry on line two of the detector CBE list in the Point Programming screen.
(For more information, refer to "Modify an Addressable Detector Point" on page 20). You
can use the fifth zone to control functions of a detector or group of detectors once the pre-
alarm level is reached. Fifth zone activations also allow ACS annunciation by a detector or
group of detectors in Action Pre-Alarm condition.
• The Pre-Alarm condition and the zone programmed will latch until system reset, even if the
sensitivity drops below the pre-alarm level.
• A subsequent alarm condition for this detector clears the Action indication from the LCD
display alarm list.
