1993 348ts aftermarket alarm problem

Hello to the 348 community. Best of health to all. I was hoping to receive some input and advice on the problem I'm experiencing with my car alarm. It is a European market car with a Gemel alarm which was installed in Europe that for some reason is going off intermittently. It is not reacting to the two button key fob at all. Any help would be greatly appreciated.

 

Thanks for your reply. I've tried searching online but a little overwhelmed. I bought the car in December 2020. It mostly sat on a trickle charger over the winter. Car was left unlocked but the alarm automatically activates to disable ignition. I was able to open doors and front, rear lids without the alarm going off. To start the car, it is necessary to press the left button on the fob and hear a certain beep to enable the ignition. Once I shut off the car, the alarm automatically starts the process again to disable ignition. Pressing the same button locks the doors and I believe arms the doors. Just out of the blue, although I hadn't armed the car or locked the doors, the alarm just started on its own to go off without anyone near it while parked in the garage. I tried with the fob to deactivate, to no avail. Now I've resorted to the battery disconnect as my battery is inside the front wheel well. It seems as the fob cannot direct the alarm or the alarm is not responding to the fob inputs. The manual is written in German as where the car originated.

 

My apologies, I should add that the fob has a red flashing light when buttons depressed and the light appears strong and bright. The alarm light in the car is situated centre on console ahead of the ashtray. It was usually always lit once I shut off the car along with a beep until recently faulting and now has no light on yet sounds off intermittently for quick bursts and or long periods however it wants.

 

Also, the alarm has its own siren. Alarm went off first as I said with nobody around for hours and car unlocked. At which point I tried using the fob to disengage but it wouldn't react. Waited until the sign stopped and then turned off the battery disconnect

 

Correction. Waited until the siren stopped, and then turned off the battery disconnect

 

Does anyone know where the general alarm unit would typically be installed on a 348. It sounds like the siren is located somewhere in the front boot passenger side

 

I haven't tried changing the fob battery, and I thought it weird the alarm siren doesn't sound once I turn off the battery disconnect yet on a few occasions it kept sounding when I turned the battery disconnect to off while the siren was on. It also makes many different alarm noises and chirps when I've left it alone after a series of alarm activities. Seems like its lost its mind, which is happening to me now. Thanks for the advice on the translation as well. See what I come up with and report back. Thanks qavion and allandwf

 

Thank you a348w. Waiting for a reply from the dealership since I've only had it since December, and would appreciate their service department address it first. But I'll check on those areas you've mentioned.

 

To all, thank you very much for the insights, recommendations, and well wishes. Great bunch of knowledgeable enthusiasts here

 

Just a follow up. Had the car at the shop, Euro Spek, part of World Fine Cars here in Toronto. Great people here and David at Euro Spek spent some time and finally just disconnected the alarm and success at last. No more siren. Thanks again to all for the recommendations and well wishes. Got my awesome ride back.
