I can see the LED on the sensor lighting up so it is detecting the movement, however, the alarm is not triggered. Once I disconnect the car battery and reconnect it, it will work again but for only three consecutive times. Is there a setting of some sorts or is this expected behavior?
Edit: Nevermind, guessing that the sensor will only allow 3 consecutive triggers in a certain time period in case there are too many false alarms, because i went back outside to test it after waiting 20 mins or so and it works again.

Yes, it's working correctly. It's called "nuisance prevention" in which the Viper will only allow it to be triggered 3 times within an hour period. However, you can turn that off in the settings for the brain.
