For anyone following the thread related to my initial post, please disregard this and skip forward to the next post related to the magnet locking and system check circuitry. I apologize for the break in focus.
Allow me to repeat myself, the magnets are self-contained. Protection from the aforementioned was built into the units and is not necessary. Each of them, including the strike plates, are isolated entities which only receive incoming voltage to pass it along.
No disrespect Paul, but the above would only just pass as constructive information for other readers by a small margin. What you're writing may be factual information backed up by your experiences or education, that much I can accept. While I am obviously the most inexperienced individual in this thread, I'm also the purpose for it to exist. I put it up to ask the advise of those more experienced and knowledgeable than myself. I didn't put it up to create a staging ground for a measuring contest nor has OldSteve, or anyone else, attempted to manifest one.
While I do not have an opinion qualified enough to comment on the proper use of diodes, I know very well the trials of being the least knowledgeable person in a room. Though I am thick or stubborn enough to ignore it, this isn't the case for everyone.
For many others lacking the same education/experience in a certain topic or field, running across a bickering match between two seasoned individuals, much less when one seems insistent on turning it into a contest, either in a thread of their own or threads they have found while looking for help with their project, can see it as overwhelming when the debate contains information, relevant or not, being thrown around like spears. It can deter them from reaching the information that may help them further down the respective thread or, worse, stop them from asking questions out of the fear of being humiliated for not knowing enough. Read those posts above again and explain what a new person to electronics but trying to learn will gain from that.
I ask that you offer your opinions constructively or not at all. Having looked back, it does seem like the only comments you've offered so far have been deliberate barbs aimed at proving how much more you know. Being unprovoked I can't say I understand why but I will say that if this is all you have to offer, I do not need your help. Please disregard my thread and spare me your opinion. Someone else, in some other thread on some other topic could greatly benefit from how much you know about what is covered here on the forums.
So far, in spite of efforts to respond to you in a positive and constructive manner, you have only posted lecturing masquerading as advice which seems to be aimed at proving you know more than someone else. You have arrogance confused with being advice.
And that is why Wikipedia is not accepted as an academic source.
Ad hominem eh? Sounds like you are on shaky ground! You are confusing an explanation with an opinion.
No one will benefit from this.
