EMD Configuration
Comprehensive View
This page gives a snapshot of all EMD parameters; the parameters will be updated automatically every 5
seconds.
The text color of the parameter indicates its status based on the administrator-configurable threshold.
The list below indicates the parameter status.
GREEN : 'normal' status.
YELLOW : 'warning' status,
RED : 'critical' status.
GREY : 'unknown' value.
The EMD provides the measurements for room temperature, room humidity,
and two alarms.
The warning/critical thresholds can be setup via the "EMD Setup" page.
EMD Setup
This page allows administrator to configure all necessary parameters of an EMD.
Set Point
The threshold of a sensor (temperature or humidity) will trigger an alarm, whenever the measurement is
over (high) or under (low) the set point. The alarm can be configured to activate at warning or critical
levels. If the checkbox is not filled, the threshold is disabled and the alarm will not be triggered. The valid
range for the Temperature threshold setting is 5 to 65, and 5 to 95 for Humidity.
Hysteresis
A sensors value could be floating around its threshold triggering multiple alarms. Setting the hysteresis
will help to prevent the alarm bouncing between active and inactive. For example, if the low warning
threshold set point is 20 and hysteresis is 3, then the alarm will activate when the value reaches 20 but it
will not become inactive again until the sensor value reaches 23.
For the contact alarm sensors, the hysteresis can be used to adjust the sensitivity of an alarm. The alarm
will be active or inactive only after the alarm stays in the same state for the duration of the hysteresis
value (in seconds). For example, if the hysteresis is 5 for an alarm, the alarm will NOT activate until the
same state has persisted for 5 seconds. This ruling also applies in reverse so that the alarm has to stay in
an inactive state for 5 seconds before the sensor status is recorded as normal.
Calibration Offset
If the measurement value of a sensor does not, for whatever reason, comply with the actual environment,
the 'Calibration Offset' setting can be configured to adjust the final value of the sensor. For example, if a
sensor reports 43% humidity for a 45% humidity environment, the administrator can configure the
humidity offset as 2% so the sensor can then adjust its final value to 45%.
Alarm Type
If an alarm sensor (water leak, security, etc) is connected to the EMD, the administrator can configure the
alarm as 'Disabled', 'Normal Open', 'Normal Close', 'High Active', or 'Low Active'. A 'Disabled' setting will
mean the alarm is inactive.
'Normal Open' and 'Normal Close' are used for a two-wire detector that will emulate an open/close state.
When the wires are closed to 'loopback' (the signal for the sensor), the sensor will detect the state as
closed. The sensor will NOT activate the alarm for 'Normal Close' in this case, although the alarm will be
activated if configured as 'Normal Open'.
'High Active' and 'Low Active' can be configured when a 'contact closure' type detector is attached. The
administrator should connect the wire to the right side of the alarm (marked as arrow-in), and 8 to 12 VDC
should be able to be detected by the EMD as 'high' state.
