Default Alarm issues, non starting

This is for a 1998 v70. Siren behind drivers wing. Throttle cable engine.

Car was unlocked with key (no remote), boot opened and alarm triggered. Couldn't get alarm to switch off so disconnected battery.
Now as soon as I connect battery again the alarm will go off. This never used to happen before if I disconnected battery. Drivers lock does not switch off alarm.
I looked in vol-fcr. Codes were alarm siren faulty and left ultrasonic. Cleared codes, still alarm is running. Disconnected alarm siren under the wing, no siren but hazards running and not starting. Even with siren disconnected the siren faulty message comes up.

I've had the door lock out... microswitch clicks... Any way to test it on bench?
Should alarm arm the moment you connect battery? Even though bonnet is open, even if doors are left open?

I'm actually not bothered about having alarm working if need be, just need hazards off and immobilizer off.

Is there anyone that is good with these alarm circuits? I don't mind replacing a part if I can find why it's triggering straight away.
