Detector Status Display
TROUBLE
*The field <Trouble Status> will contain a device trouble message. Refer to this panel's Operations
manual for information on these messages.
Line 7 - The custom label for this point
Line 8 - Continuation of the point's custom label, first zone, and device type
Lines 9, 10 - A display of all the zones that contain the current point being read.
Lines 11through 14 -These lines will have values in them only if the device is a detector. They will
not display for wireless detectors.
Line 11
VALUES:
The screen displays the Alarm and Prealarm values that are in effect when read status is
requested. For example, if occupied settings are in effect, occupied values will display
121% OF ALARM - This field gives the detector reading as it relates to its preprogrammed
alarm level value (indicated in the next line on the screen). The example above shows the
detector exceeding the alarm level by 21%.
145% OF PREALARM - This field gives the detector reading as it relates to its
preprogrammed prealarm level value (indicated in the next line on the screen). The example
above shows the detector exceeding the prealarm level by 45%.
If the detector is an Alert heat detector, the value is indicated by a temperature reading
(example: 148 DEGREES F).
Line 12
The screen displays the Alarm and Prealarm levels that are in effect when read status is
requested. For example, if unoccupied settings are in effect, they will display.
ALARM: 6=1.66% - Six is the preprogrammed alarm level value for this detector: its value is
1.66%, indicating the percent per foot obscuration value assigned to level 6.
PREALARM: 3=0.47% - Three is the preprogrammed alarm level value for this detector: its
value is 0.47%, indicating the percent per foot obscuration value assigned to level 3.
Line 13
ACTION/STATUS: NONE/VERY CLEAN - This displays the maintenance status of the
device. The message that appears in this field depends on the drift compensation value. A
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 will not display for Acclimate detectors.

Intelligent Sensing Applications
Description
No action necessary. The detector readings are near
ideal.
No action necessary. The detector will activate at the
selected sensitivity level.
Clean the detector soon. The detector may cause a
false alarm because it has reached the drift
compensation tolerance value.
Clean immediately! The detector is a false alarm risk.
The drift compensation tolerance value has been
exceeded.
