Why does my house alarm keep going off

Since a recent power cut, my alarm keeps going off. What is going on with it? Can I try anything before calling someone?

"Needs a new back-up battery installing.

Back up batteries should be replaced every 4 years.

Old back up batteries won't supply the system with power in the event of a power cut.

The majority of alarm systems will power up in full alarm mode as standard"

"You will most likely need to perform a user reset with your user code. If this doesn’t work, it could possibly be the back up battery in your panel."
