I just fitted an aftermarket alarm kit from Falcon (Predator 2 Way Communication & GSM Tracking) which took a good 5 hours. Although not thatcham approved it is still a cat1.
Huh - I sniff cow manure! Cat 1 IS a Thatcham standard - so if it isn't Thatcham approved, then it is NOT Cat 1 approved. Therefore, it will NOT be approved nor even recognised by the insurance industry!
I usually use these systems as I get to control the car via telephone anywhere in the world. Main functions of this alarm is that it will call your mobile (Any 2 assigned numbers) when the car is being tampered with or if the alarm goes off.
So - I take it you are a trader? Hope you seek approval from this sites owners.
And genuine Tracker units will call four numbers (even more if you ask them) - AND automatically alert the Police (all of the UKs 52 Police Forces), AND alert UK Boarder Authorities.
You can listen to whats going on inside the car via mic and talk to vehicle occupants if needs be.
That's nice. Do you offer them a cup of Earl Grey? Perhaps with some HobNobs!
Immobilising the vehicle, turning off/on the alarm etc etc.
Isn't that EXACTLY what the factory fitted OEM system does!
Usually these are best for older generation cars or imports as they dont have a "CAN-Bus" system like the Golfs. If you or the fitter isn't careful as to which wires you cut, your dash can light up like a christmas tree on steroids.
Then why post this here????
