Well done! This is configured as a timer circuit, meaning it will shut off after a very short time. Check this for 555 modes _ http://everycircuit.com/circuit/5212107531091968 I suggest if you want it as an alarm to use the Bistable mode, with a transistor to isolate the pir. For a timer mode, your circuit, increase the value of the capacitor and the resistor too have longer on time. Also increase the simulator time for more real-time appearance.
