Astra Gsi Alarm Going Off Randomly

[Pepsi2510]

The alarm on my Gsi keeps going off this morning, even with the car unlocked... ive had to leave it running to stop it annoying the neighbours lmao, I put a new battery into the car this week and i did notice that the alarm didnt sound when i disconnected it... any ideas asap as the car running outside cant be doing the fuel any good

thanks

Sounds like Factory battery back up siren is pooped
this is classic when batterys get depleted in siren
