Good Morning Folks!
I have recently started a role as a field engineer for door entry system, I come from a specific product a well known brand however with this field role now I have to work all different kind of door entry systems which is a bit different and challenging for me, I don't mind it and trying my best to understand systems when on site. Recently I came across a system which appears very different and was not able to resolve the issue. I am attaching images to help you guys understand what I saw. This is a 11 flat block, MED is maglock, A fob reader and PTE and a Service/Trades button.
At the back of the reader I have terminals 12v C, 0v H, Exit O, Exit Z, Lock +, Lock -
what does C and H represent? What is Exit O and Exit Z? Where does the fob data saved?
Lock + and Lock - go into a paxton 12v relay at the power side and on the relay side there are two wires fitted at C and NC, I understand that the reader was designed for strike lock i.e power to release but since a maglock has been used a relay had to be used to make switching 12v via NC , This NC should be going to lock from what I understand.
On the buttons side there is a solid copper wire going through all the buttons which I am assuming 12vdc as looking at how diodes are fitted and other side must be 0v. The wires connected to each button would go to the flats to provide 12v to handset and cause it to ring. (Please correct me if i am wrong)
I do not know the wiring done on the speakder modular side, Unfortunately I did not take more photos as I had to go to another job. I tried to search the internet for this modular wiring diagram but did not find one, its too old and available to purchase however no wiring information. If anyone knows this modular type or has some sort of diagram please let me know it will be greatly appreciated.
Also there is a box on the wall which has power supplies and timers which I am also trying to make sense, its definatley for the Service/Trades button but so far wasn't able to make sense of it.
I spoke to installations company for some sort of wiring diagram for the site but they don't have one and simply told it's either a 4 wire +n or 2 wire intercom system.
