Forester: Security system went off

[P T]

This morning I heard the familiar honk- honk- honk of a burglar alarm.
I looked out the door to see which one of my bonehead neighbors was
making the noise, and I was the bonehead. It was my 04 Forester. After
a few more seconds it stopped.

But here's the bewildering part: my base model Forester does not have a
security system!
What does this mean?

Even without the security system, if you have the keyless entry there
is a panic feature. Is it possible you had the remote in your pocket
and accidentally pressed the lock button for several seconds which
would set off the panic mode?
