HART XL DETECTOR MONITORING AND CONFIGURATION
Once the connection has been made to a Detectoras described in the previous chaptera wide range of
display, control and configuration programming options are available. This chapter details those options.
While viewing the status of a Detector does not require a password (except when viewing through an IIM),
an installer level password is needed to make configuration changes. The owner-level password gives
access to the smoke history download, event history download, the maximum/minimum smoke and airflow
levels, print configurations, view software versions and allows the Detector time and date to be set.

STATUS INDICATORS IN THE DISPLAY CONTROL WINDOW
There are several groups of indicators on the Display and Control window. In a normal condition, without
active alarms or faults, the Status Box displays 'Normal' in green and the yellow smoke-level bar graph may
be moving below the Pre-Alarm 1 threshold. The green Average and Night and yellow Isolate and Auto-
Setup lights may also appear, depending on the system configuration.
1.
Status
. This shows the current status of the system. Normal will appear in green, Fault in yellow and
Alarm in red.
2.
Smoke-Level Bar Graph.
This is a dynamic display which shows the current smoke level. There are
two red pointers which show the programmed thresholds for Alarm 1 and Pre-Alarm 1.
3.
Smoke Level.
Smoke level is displayed in units of % and %/m or %/ft.
4.
Alarm Indicators.
There are four red alarm lights, corresponding to the four alarm thresholds: Alarm 2,
Alarm 1, Pre-Alarm 2 and Pre-Alarm 1. These will track the alarm state of the device, taking into ac-
count any time delays or signal conditions. These lights will also follow the activation of the Isolation
switch and, if the Detector is isolated, will not be lit even if the threshold is exceeded. The number of
alarm indicators showing will vary depending on system settings. To view actual thresholds, select the
<Smoke>
button.
5.
Other Status Indicators.
Average.
Lights green when Signal Averaging is enabled. This is considered a normal operating
condition.
