detector will automatically compensate for environmental contaminants and other factors over
time, until the tolerance value has been exceeded. The FACP will signal a trouble condition
when this level has been reached. Refer to the following table for messages and required
action.
Line 13 does not display for Acclimate detectors.
Line 14
PEAKS: 56% - This value represents the highest percent per foot obscuration reading taken
by this detector. It can be a historical figure, and does not necessarily represent the highest
reading for this particular alarm. Re-initializing the detector would reset this value to zero.
VERIFY COUNT: 02 - This displays the number of times the detector has gone into
alarm. This count aids in differentiating false alarms from actual alarms by showing repeated
alarm events that have come into the device. In this example, the detector has gone into alarm
two times since the verification count was begun. The FACP will signal a trouble condition
when the verify count is exceeded.
CO-OP: D100,158 - Indicates the address(es) of any detector(s) linked with the detector
that’s in alarm for Co-operative Multi-alarm Sensing. This field does not display for
Acclimate detectors.
Line 15 - The current time and date are displayed in this line.

1.7.3 Multiple Event List
Pressing the Multiple Event List soft key shows off-normal events simultaneously in groups of
eight. One event is shown at the top, and seven are shown in the list below it. The list will consist of
the events immediately following the event at the top, with the priority of event types determined
by the programmed Event Ordering setting (USA or Canada).
•Using the Next Selection/Previous Selection special function keys to scroll through the list
will replace the event at the top of the screen with the first event in the series displayed below
it.
•Using the Up/Down arrow keys to scroll through the list will not replace the event at the top
of the screen: pressing the arrow keys will scroll a cursor through the seven events below
without changing what is displayed at the top. The arrows will scroll through the list of events
Message Description
Replace/Malfunction Replace the defective detector. The detector may not
operate properly.
None/Very Clean No action necessary. The detector readings are near ideal.
None/Clean No action necessary. Although not ideal, the detector will
activate at the selected sensitivity level.
None/Fairly Clean No action necessary. The detector will activate at the
selected sensitivity level.
Needs Cleaning Clean the detector soon. The detector may cause a false
alarm because it has reached the drift compensation
tolerance value.
Needs Immediate Cleaning Clean immediately! The detector is a false alarm risk. The
drift compensation tolerance value has been exceeded.
