I am not an alarm engineer by any means so most of you will probably not take any notice of this post all matt was asking for is some help not your bank pin number I dont understand why most of you are so defensive with helping people when they have a question we all had to start in our chosen profession somewhere and wether you ask the question on a forum or to a person standing next to you what is the difference you should still offer your best advice possible what I probably think is most of you probably dont even know the answer and rather than be honest and say 'sorry I dont know maybe there will be someone along shortly who will help'it seems that you would rather put somebody down who is asking a geniune question.
