AWACS™ Applications Detector Status 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.
P
REALARM: 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.
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 exceeds 20.
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 will not display for Acclimate detectors.
Line 15 - The current time and date are displayed in this line.
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.
