Power ON Alarm

This video explains how to make alarm for Power ON indication.
When mains power resumes, alarm OR hooter gets on for a predefined set time and automatically gets off after set time.
We have used star-delta timer along with hooter, which involves least number of wires to be connected to make a Power ON Alarm.
