the tamper warning alarm sounds several times per day,does not operate alarm proper,cancels ok but operates again after aprox 1 or 2 hours

it could be a short between tamper and zone connection especialy at door contact,as water might be getting in it,it could also be a loose cover on any pir you may have,or juction box,could also be fault in bell box,you really need a test meter set on ohms scale,(resistance) to check properly.
