Set Point (High)
The high threshold(s) at which the sensor (temperature or humidity) will trigger an alarm(s). The EMD can be
configured to activate two high set points Warning, and Critical. 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
°
C to 65
°
C,
and for Humidity threshold setting is 5% to 95%.
Hysteresis
A sensors value could float around its threshold triggering multiple nuisance alarms. Setting the hysteresis will help
to prevent the alarm bouncing between active and inactive. For example, if the High Warning threshold set point is
40
°
C and hysteresis is 3, then the alarm will activate when the value reaches 40
°
C but it will not become inactive
again until the sensor value reaches 37
°
C.
For the contact alarm sensors (Alarm-1 and Alaarm-2), 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-1 (Sec) & Alarm-2 (Sec)
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.
Device Status
The EMD can be configured as “Disabled” or “Auto”. The setup should be configured as “Disabled” if an EMD is
not attached to the port or would like to turn of the EMD feature. The EMD type will be auto detected by the
RemotEye III if configured as “Auto” and if the EMD is plugged into the COM port.
