the only switch you need to check is the door switch,its a glass switch and is very broken if you are a bit rough when fitting it,remove the switch short the switch wires then see if your panel resets ,if it does then the switch is open circuit and you need to replace it and as I said check that you have not wired the switch wires to the tamper circuit in the infra-red beam if you have done this the alarm will trip every time the beam picks you up
