Might be worth having a word with Hamilton and Palmer. They can be contacted at
sales@hamilton-palmer.co.uk I think they made the PA1000 and P2000 alarms for Porsche
Have not heard of a PA100
Silly question, are you sure the last zero has not rubbed off the key fob, I have a 993 Targa and the fob shows the alarm to be PA1000
Also as others say, be very clear with declarations to insurance companies
Had a refusal to insure my car because the lights had been upgraded; me thinks it is now safer, at least I can now see the road in the dark! Stange world we live in when you cannot gat insurance just for making the car safer.
Everytime I find something different about my car I let the insutrance company know and make sure my broker has the notification logged, that way no argument.
