2.0Alarm menu
2.1List of alarms
By clicking on the Alarms menu a list of alarms will be shown.
The contents in the list of alarms depend on the selected filtering criteria. These criteria are Priority, Status, Event text, Source and Place. Each of these criteria is explained below.
It is possible to see the priority, time stamp, customer name and controller ID, place, object number, event text, status and accept status. Each of these information is explained below.
The buttons on the lower right side of the window makes it possible to show History of alarms for a specific period of time or to quickly Accept All alarms in the list. The list can also be exported to a CSV file.
2.2 Selecting Priority
The alarms which can be generated by DECS 2.0 each have a predefined priority. In this way the alarms can i.e. be filtered to have only the highest priority alarms (1 – 601) shown in the list.
By selecting a Priority in the dropdown list then only alarms with that priority or higher will be shown in the list.
Alarms of highest priority are defined as ‘1 – 601’ and lowest priority as ‘5 – 201’.
The predefined priority of each alarm is shown in the lists of supported alarms.
2.3 Selecting Status
When an alarm is triggered then the status of that alarm will be set to On. This happens when the trigger condition for that alarm is fulfilled, i.e. a sensor is disconnected.
If or when the trigger condition for that alarm is no longer fulfilled then the status of that alarm will be set to Off, i.e. if the sensor is reconnected.
The trigger conditions are described in the lists of supported alarms.
In the Status dropdown list it is possible to select only to show alarms with a particular Status in the list. If ‘None’ is selected then no Status filter is applied.
The other options in the dropdown list provide filter criteria which depends on both the current status of the alarm (On/Off) and whether or not the alarm has been accepted by a user (Accepted/ Unaccepted). For example, select ‘On Unaccepted’ to show only the alarms which are currently On and which have not yet been accepted by a user. Alternatively, select the ‘On Off Unaccepted’ option to show all unaccepted alarms regardless if Status is On or Off.
Figur 1 shows the Alarms window accessible via the Alarms menu.
Figur 2 shows how to select Priority in the filter conditions.
Figur 3 shows how to select Status in the filter conditions.

2.4 Specifying Event Text
Each alarm supported by DECS 2.0 has a predefined Event Text which is shown in the ‘Event Text’ column in the list of alarms.
By specifying a filter criteria to be alarms with a specific Event Text then only alarms which have this Event Text will be shown in the list.
It is possible to specify all of the Event Text or just the initial part of the Event Text, i.e. by specifying “Reachability”, then all alarms starting with that Event Text will be shown. The filter is not casesensitive.
The predefined Event Text of each alarm is shown in the lists of supported alarms.
2.5 Selecting Source
DECS 2.0 supports ECL Comfort 296 / 310, OPR20 and OPR10 controllers as source of alarms.
By selecting a source as a filter criteria then only the alarms from that specific source will be shown in the list of alarms. If ‘All’ is selected then alarms from any of the sources will be shown in the list.
The alarms supported by each source are shown in the lists of supported alarms.
2.6 Selecting Place
One or more Places can be created in the General Settings available in the Administrator menu.
Each of these places is selectable in the Place dropdown list. Only the alarms from that specific Place will be shown in the list of alarms.
2.7 Selecting Object Number
You can set a filter for the object number to find only the alarms from that one.
If you want to see the controller overview of a controller, which have an active or inactive alarm, then you have to click on the object number of that controller. This is a hyperlink and the system will jump to the controller overview display of the controller, on which the alarm appeared.
2.8 Sorting the list of alarms
The list of alarms can be sorted ascending or descending based on any of the columns shown in the list of alarms.
Click on the title of the column to be used for sorting the list. By clicking the same column again it will be sorted in reversed order.
The column used for sorting is indicated by an arrow-down (descending) or arrow-up (ascending).
Figur 4 shows how to specify an Event Text in the filter conditions.
Figur 5 shows how to select a specific Source in the filter conditions.
Figur 6 shows how to select a specific Place in the filter conditions.
Figur 7 shows how to select object number.

2.9 Alarm on sensors
The ECL controller can be configured to monitor one or more sensor inputs and then trigger an alarm if a sensor is short circuited or disconnected.
It is described in the installation guide for the application key installed in the ECL controller how to configure it.
To make the ECL controller monitor an input then it must be activated via the Raw Input Overview menu in the controller.
The ECL controller will then show a magnifying glass next to the sensor input. Only sensor inputs used by the application itself can be monitored for alarms.
The sensor input has a measuring range from -60 ... 150 ° C. If the input is exceeding these limits then the alarm is triggered.
