get a flashlight or other focused beam of light and shine it across a walkway,and when the person breaks the beam of light the sensor stops sending a signal and a relay would switch over and that triggers the alarm....(a relay will change the circuit route) power on = one circuit path ...power off = a different circuit path
your car has one for the starter ..turn the key and it switches to path-1 routing massive power to the starter....key releases and starter stops = path-2 routing regular power to the car
