The Alarm Periods module is where you create and configure time periods for use with alarm actions. Use this module to specify business-hours and after-hours periods including public holidays.

# What is an Alarm Period?

An alarm period is a time period during which an alarm may be triggered. An associated set of alarm actions can be defined for alarms that are triggered within an alarm period.Note that the alarm actions do not have to be performed during the alarm period, only the triggering event must fall within the alarm period.

Alarm periods are used to specify which set of alarm actions should be performed depending on when the alarm is triggered. In particular, they are used to distinguish between business hours, and non-business-hours including after-hours periods and public holidays.

# Defining alarm periods

A default set of business hours periods is provided for each day in the week. You cannot delete these periods or define new business hours periods. What you can do is:

- Modify the existing business hours period for any day. Any times which are not defined as being within a business hours period is considered to be after-hours.
- Add an after-hours period on a specific day. For example, to define a public holiday.
