## Alarms An alarm is a message sent from an alarm source (usually a microblock in a control program) to the WebCTRL® application to notify you that certain conditions exist, such as a piece of equipment has stopped running or a temperature is too high. When the WebCTRL® application receives an alarm, it displays information about the alarm on the Alarms page. It can also perform alarm actions to inform personnel of the condition and to record information about the alarm. An alarm source can also send a return-to-normal message when the alarm condition returns to its normal state. Alarm sources and the alarms they generate are assigned to categories, such as HVAC Critical or HVAC Maintenance, to help you work with related alarms. The application engineer usually sets up alarm sources in the EIKON® application. In the WebCTRL® interface, you can: View, troubleshoot, acknowledge, and delete alarms Set up the alarm actions that the WebCTRL® application performs Edit alarm sources that were set up in the EIKON® application or set up new alarm sources to generate alarms Customize alarms by changing the category or message NOTE Besides the alarms that you set up, the WebCTRL® application has built-in system and equipment alarms.
