When sensor readings are frequently out of range or the readings are not as expected, this may result in multiple alarms and alert fatigue. Frequent alarms may be related to the placement of a probe, sensor settings, or the monitored refrigeration unit.
All or some of the below symptoms may be present.
Monitored Asset continuously enters an Alarm state with an Out of Range, Past Alarm Delay status,
Monitored Asset continuously enters a Warning state with an Out of Range status.
Alerts continuously received by staff indicating the Monitored Asset in an Alarm state.
The sensor red LED indicator flashes frequently.
The sensor frequently emits an audio alert.
The below steps should be performed to resolve the issue.
Readings may be affected if a probe is not mounted correctly.
Does the probe have a thermobuffer? If yes, verify it's mounted correctly. Verify it meets the Probe/Thermobuffer mounting guidelines
If the probe cable is routed through a door hinge or seal, ensure the probe cable has enough slack. You want to ensure the opening and closing of the door does not cause the probe to become detached from the sensor input jack.
The probe cable is secured at every 6 inches (15.2 cm) of the cable run and at all turns. This will prevent the risk of accidentally pulling out a cable or moving the probe/thermobuffer from its fixed mounting position.
The probe cable is free of defect.
The probe plug and sensor input jack are free of debris.
The probe is inserted properly into the sensor jack.
A sensor's Normal Condition or Alarm Delay setting may be resulting in multiple alarms.
From OneVue, go to Monitoring > Monitored Assets > from the list, select the Monitored Asset > from its profile, select the Sensor Type.
Verify the sensor's Normal Condition setting.
A reading either below or above the normal condition will result in an out of range reading.
Select Show Advanced Options and verify the sensor's Alarm Delay setting.
If set too low, this may result in multiple alarms and continuously going back into a Normal state in short time periods. This type of short excursion may be due to the opening and closing of a refrigeration unit door.
The Alarm Delay is the amount of time OneVue delays setting the sensor and Monitored Asset to an Alarm state when in an Out of Range status. When it remains in an Out of Range for the time period set in its Alarm Delay setting, the sensor and its Monitored Asset are set to an Alarm state with a status of Out of Range, Past Alarm Delay.
Is this a newly installed or repaired refrigeration unit? If yes, It may take up to two to seven days for the temperature to stabilize.
Verify the refrigeration unit temperature is set to the facility's SOP and/or policy for the condition being monitored.
It's recommend to review the Monitored Asset's Reading History. The reading history may help to identify a pattern of reading excursions.
If reading excursions continue, it may be necessary to escalate to your facility maintenance department to determine if repairing or replacing the refrigeration unit is required.
