whats the manufacturer name of the alarm/immobiliser on the A2

Trying to fill in insurance proposal form and its asking for name of manufacturer of alarm system and immobiliser,
Thought it was just Audi, can anyone elaborate anymore on this!

The alarm is made by Audi and fitted as part of the standard spec - This is the description from the price list

Anti theft device with interior ultrasonic protection (Thatcham Category 1 approved)

Also covered on page 5 of this PDF brochure (actually Page 8) - http://www.a2oc.net/forum/attachment.php?attachmentid=13521&d=1382473436
