Could anyone tell me what sort of turbo timer is compatable with a Toad (Ai606) cat 1 immobiliser/alarm

 

if the alarm is a decent one you should be able to use any turbo timer.the alarm has to be set for passive arming. when you turn the car off if it is running on the timer lock it as normal with the alarm. the alarm will not set untill the car has stopped running and it reconizes all electrics have switched off once it stops running after a short period it should set it self
get intouch with the alrm people and they should be able to verify this and set it up for you
