alarm malfunction

Hi

My newly purchased '99 911 Carrera Cabriolet tends to sound its alarm randomly; is this an electrical malfunction or possibly caused by a parking tag that hangs from my mirror or something else that is triggering it? Is there a way of disabling it until I get it checked out? I don't have a manual for it yet.

Thanks.

Could be your parking tag as the interior Infrared sensors are mounted within the interior light assembly next to the mirror.

The 2 black looking oval shaped pieces are the windows for the infrared sensors which monitor the interior cabin space for movement etc. - Your tag might be interfering with the infrared signal with the tag being very close to the sensors.

You can disable the interior sensors when you arm the alarm system by pressing your key fob button twice instead of just once - you should get a quick chirp to indicate this status.
