• They show one of the managed states. See Sensor/Actuator States
(on page
123).
• For managed 'numeric' sensors, their readings are retrieved and
displayed. If any numeric sensor is disconnected or its reading
cannot be retrieved, it shows "unavailable" for its reading.
Unmanaged sensors/actuators:
• The BCM2 neither communicates with unmanaged
sensors/actuators nor retrieves their data.
• Unmanaged sensors/actuators are listed only when they are
physically connected to the BCM2. They disappear when they are no
longer connected.
• They do
not have an ID number.
• They show the "unmanaged" state.
Sensor/Actuator States
An environmental sensor or actuator shows its real-time state after
being managed.
Available sensor states depend on the sensor type -- numeric or state
sensors. For example, a contact closure sensor is a state sensor so it
switches between three states only --
unavailable , alarmed and normal .
Sensors will be highlighted in yellow or red when they enter abnormal
states. See
Yellow- or Red-Highlighted Sensors (see " The Yellow- or
Red-Highlighted Sensors " on page 90, on page 121).
An actuator's state is marked in red when it is turned on.
Managed sensor states:
In the following table, "R" represents any numeric sensor's reading. The
symbol <= means "smaller than" or "equal to."
State
Description
normal
 For numeric sensors, it means the
readings are within the normal range.
 For state sensors, it means they enter the
normal state.
below lower critical "R" < Lower Critical threshold
below lower warning Lower Critical threshold <= "R" < Lower
Warning threshold
above upper warning Upper Warning threshold < "R" <= Upper
Critical threshold
