Alarm activating for no reason, please help

[Reggie-rock]

Has anyone have a clue why my alarm randomly goes off for no reason? This has happened twice so far today and has never done it before.
What can I check or do ?
Thanks

Could be your battery. Check the charge.

Possible cause is the internal alarm batteries have failed. quite a common issue and costs around £80 from MB

It could be the alarm siren.

Get it plugged into a Star.
