### Setting up an alarm source in the WebCTRL® interface The application engineer usually sets up alarm sources in the EIKON® application. In the WebCTRL® application, you can: Edit an existing alarm source’s settings or set up a new alarm source to generate alarms. Set up all alarms for a piece of equipment at once on the Alarm Sources tab of the equipment's Properties page. Simulate an alarm to test its setup. Two types of microblocks generate alarms in control programs. Alarm microblocks include logic that takes into account conditions such as space occupancy. I/O point microblocks can generate an alarm when the present value exceeds defined limits (analog) or when the present value changes to an off-normal state (binary). This type of microblock is typically set up for analog points to generate alarms for sensor failure. Alarm microblocks and I/O microblocks can have similar names. So, when you are going to enable an alarm source, first look for an alarm microblock on the Geographic or Network tree.

#### To set up, edit, or disable alarm sources To set up, edit, or disable a single alarm source On the Geographic or Network tree, select the alarm source (microblock). Click Alarms, then select the Enable/Disable tab. Make changes to the fields as needed. The fields can vary for different types of alarm sources. See table below. Click Accept. TIP To set up all the alarms for a piece of equipment at once, click Properties, then select Alarm Sources.
Field | Notes
--- | ---
Potential alarm source | Check to enable the alarm source to generate alarms. Uncheck to disable the alarm source.
Alarm | Check to have the alarm source generate an alarm when the specified conditions occur. For a binary input, enter the conditions for generating an alarm. For an analog input, type the low and high limits that, when exceeded, will generate an alarm. Deadband The amount inside the normal range by which an alarm condition must return before a return-to-normal notification is generated. EXAMPLE NOTE If Status is checked, the alarm condition currently exists.
Return to Normal | Check to have the alarm source generate a return-to-normal when the alarm condition returns to a normal state.
Alarm requires acknowledgment | Check to have the WebCTRL® application require that an operator acknowledge the alarm.
Return requires acknowledgment | Check to have the WebCTRL® application require that an operator acknowledge the return-to-normal.
Classified as critical | This property determines the color of the system-wide alarm button when the alarm comes in. = Critical = Non-critical
Event State | The current state of the alarm source can be: Normal—value is normal Off normal—the value is not normal (binary only) Fault—the alarm source microblock may be misconfigured High Limit—the value exceeds the normal range (analog only) Low Limit—the value is below the normal range (analog only)
BACnet Configuration: Dial on alarm | Check to have this alarm immediately delivered through a modem connection. NOTE When monitoring your system through a modem connection, non-critical alarms are stored in the gateway until one of the following happens: a critical alarm occurs the gateway is contacted by the WebCTRL® application the gateway buffer is full, at which time all alarms are sent to the WebCTRL® application
Notification Class | Do not change this field.
To set up, edit, or disable multiple alarm sources simultaneously On the Geographic or Network tree, select the area, equipment, or controller containing the alarm sources. Click Alarms, then select the Enable/Disable tab. In step 1, select the categories that contain the alarm sources. NOTE In step 1 and step 2, Ctrl+click, Shift+click, or both to select multiple items, or check Select All. In step 2, select the alarm sources. Make appropriate changes in step 3. Click Accept. NOTE Click View Selected Sources to view or change settings for each alarm.
#### To simulate an alarm To test the setup of an alarm source and its alarm actions, you can simulate an alarm or its return-to-normal. On the Geographic tree, select the alarm source (, but not ) whose alarm you want to simulate. On the Alarms > Enable/Disable tab, check Enable next to Alarm or Return to Normal. Click Simulate next to Alarm or Return to Normal. Select the equipment on the tree, then select the View tab to see the alarm.
#### To view all instances of an alarm source To find all instances of an alarm source at and below a selected area: On the Geographic or Network tree, select an area. Select the Message, Actions, Enable/Disable, or Category tab. Select an alarm source from the list in step 2. Click View Selected Sources. Each path in the dialog box links to the alarm source microblock. NOTE You may be able to change settings that relate to the tab you selected.
