# Responding to alarms in AWS IoT Events
Responding to alarms

Responding to alarms effectively is an important aspect of managing IoT systems with AWS IoT Events. Explore various ways to configure and handle alarms, including: setting up notification channels, defining escalation procedures, and implementing automated response actions. Learn to create nuanced alarm conditions, prioritize alerts, and integrate with other AWS services to build a responsive alarm management system for your IoT applications.

If you enabled [acknowledge flow](https://docs.aws.amazon.com/iotevents/latest/developerguide/iotevents-alarms.html#acknowledge-flow), you receive notifications when the alarm state changes. To respond to the alarm, you can acknowledge, disable, enable, reset, or snooze the alarm.

1. In the navigation pane, choose **Alarm models**.

1. Choose the target alarm model.
