• Lines 7-8 specify the user defined loop, zone, and device type.
• Lines 9-10 display all the CBE zones that contain the current point being read; these lines only appear for smoke detectors.
• The percent values in Line 11 (VALUES) represent the amount of smoke detected by the device. If these values are above a certain
percentage chamber value, the panel will give a prealarm warning, then an actual fire alarm.
• Line 12 (ALARM) displays detector sensitivity levels for Alarm and Prealarm, both of which range from one to nine, one being the
most sensitive. These levels can be set via the NCA-2 Programming menu.
• Line 13 (ACTION/STATUS) is 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 contaminates 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. When READ
STATUS is performed for a detector, the displayed message is based on the percentage of the drift compensation tolerance that is
used (see Table 4.2).
*
Message
None/Very Clean
None/Fairly Clean
Needs Cleaning
Needs Immediate Cleaning
*
For detectors in CLIP mode, the status will display as None/Very clean until it displays Needs Immediate Cleaning. No intermediate levels are displayed.
• Line 14 shows PEAKS, which is the highest value read by the device. Also shown is VERIFY COUNT, which displays how many
times the panel detected an alarm. This verification aids in differentiating false alarms from actual ones by showing repeated alarm
events that have come in on this device. The last element on this line is Detector Cooperation (DET CO-OP: CTR in Figure 4.13).
Detector cooperation is when multiple detectors exist in close proximity and are programmed to operate together in order to make
smoke detection more accurate. The text after the colon can be an abbreviation denoting detectors used together to detect smoke.
Refer to Table 4.3 for detector cooperation abbreviation descriptions.
NOTE: Verify Count is only available for detectors that support the feature.
FSC-851 IntelliQuad detectors display the following in line 14:
PEAKS:56% COUNT:02 CO:200PPM TEMP:100
The CO figure is a carbon dioxide (200 parts per million).
• Line 15 displays the current time and date.

Drift Compensation % Description
Less than 50 No action necessary. The detector readings are near ideal.
50 - 69 No action necessary. The detector will activate at the selected sensitivity level.
70 - 79 Clean the detector soon. The detector may cause a false alarm because it has
reached the drift compensation tolerance value.
80 - 100 Clean immediately! The detector is a false alarm risk. The drift compensation
tolerance value has been exceeded.
