Hello,
I have a existing alarm system which has a magnetic door switch connected to it. Would it be ok to connect the same switch to the PI? i.e. connect a pair of wires from the PI to the same input as the switch on the alarm panel?

Be careful to match the voltage and current before trying. Otherwise you could get blue smoke 
. To be sure, use isolation circuit switch like this:
