• An ultrasonic intrusion detection system from Autoroofs has a microprocessor which discriminates againsts false alarms.
The processor is programmed with seven levels of movement, which, if activated during a five-second period, will trigger the alarm. This means that a trapped fly or retracting seat belt will be detected, but, because they will not register on all seven movements levels, they will not trigger the alarm. A smash and grab or intentional intrusion, however, will.
