Alarms

A key functionality in the CoolSens system is the ability to send warnings and alarms when measurement values are outside the established limits. Effective management of these notifications allows for a quick response to adverse environmental changes, which is especially important in areas requiring strict climate control.

Introduction

Within the CoolSens system, there are two types of notifications:

Warnings – These are sent when the temperature or humidity levels exceed recommended values but have not yet reached the alarm level. These warnings aim to alert users to potential issues, allowing for preventive actions to be taken.
Alarms – These are generated in critical situations when the temperature or humidity levels exceed the set alarm thresholds. These alarms require immediate intervention to prevent damage to stored products, equipment, material degradation, or other adverse effects resulting from uncontrolled climatic conditions.

tip To enable the system to send notifications, the appropriate alarm thresholds must be set. Warning and alarm thresholds are defined separately for each device. For more information on this topic, refer to the chapters on device configuration.

Sending alarms

When the warning threshold is exceeded (the optimal operating range is exceeded) or the alarm threshold is exceeded, the system records an alarm event.

Active alarms

An active alarm is indicated on the top bar of the program. The label on the alarm icon shows the number of active alarms, which are those for which values are still exceeded beyond the warning or alarm thresholds (or have not returned to normal values within the accepted hysteresis). The hysteresis is designed to eliminate an excessive number of transmitted alarms in situations where the measured value oscillates near the threshold value.

tip The hysteresis for temperature is 1°C, and for humidity, it is 1%. Therefore, if the alarm threshold is set at 24°C, an alarm will be triggered when this value is exceeded and will remain active until the temperature drops to 23°C.

Clicking on an alarm in the list will take you to the alarm list view and display the indicated alarm at the top of the list.

Clicking on the View all alarms button will display a list of all alarms.

Email notifications

tip If you want to receive notifications via email as well, enable the Email Notifications option in your User Profile.

Alarm List

The alarm list is available from the main application menu (ALARMS command).

The alarm table contains the following information:

Alarm icon: an orange icon indicates a warning, and a red icon indicates an alarm;
Date and time of receiving the notification;
Sensor where the value exceeding the warning or alarm threshold was measured;
Notification Content;
Measured Value;
Status: An exclamation mark in this column indicates that the value is still exceeded and the warning or alarm condition is still active!

Alerts are displayed in chronological order by default. You can sort them by a selected column by clicking on its header. Clicking the column header again will change the sort order.

The search field allows you to filter the list of alarms – you can enter part of the sensor name, date/time, or measured value – the system searches for the entered phrase across all columns.

The filtering functionality allows you to display events with a selected status from selected sensors or only those related to temperature or humidity.

tip Filtering settings are remembered across sessions, so if you change app views and return to viewing alerts, note that not all alerts may be visible in the list.

Each item on the list represents a received alarm or notification and contains the following information:

Alarm icon: an orange icon indicates a warning, and a red icon indicates an alarm;
Measured value, notification content, sensor name where the value exceeding the warning or alarm threshold was measured, and date and time of receiving the notification;
Alarm status: An exclamation mark in this column indicates that the value is still exceeded and the warning or alarm condition is still active!

Search field allows you to filter the alarm list – you can enter a fragment of the sensor name, date/time, measured value – the system searches for the entered phrase in all columns.

Filter functionality allows you to display events with a selected status from selected sensors or only those related to temperature or humidity.

tip Filtering settings are remembered across sessions, so if you change app views and return to viewing alerts, note that not all alerts may be visible in the list.

Archiving alarms

As you use the system, the list of alarms can grow. If you don’t want inactive alarms to be visible, you can archive them.

The HIDE button at the end of each row is used to archive the specific alarm. It will no longer appear on the list but will not be deleted from the account history and will be visible in the alarm report.

NOTE It is not possible to hide alarms that are active, i.e. the value remains outside the specified limit (or has not returned to the recommended value by an amount greater than the adopted hysteresis).

If you want to archive multiple alarms at once, select the desired rows using the checkbox in the first column of the table and click the HIDE SELECTED button. Click the checkbox in the column header to select all alarms on the current page of the table.

tip The check box in the table header selects all alarms visible on the displayed page. It does not select all alarms in the entire table.

The HIDE button at the end of each row is used to archive the specific alarm. It will no longer appear on the list but will not be deleted from the account history and will remain visible in the alarm report.

tip It is not possible to hide alarms that are active, i.e. the value remains outside the specified limit (or has not returned to the recommended value by an amount greater than the adopted hysteresis).

If you want to archive multiple alarms at once, select the desired items using the checkbox in the alarm header and click the Hide selected option available in the menu under the button with three vertical bars. This menu also contains the Select all option, which selects all alarms visible on the displayed page of the table.
