In the alarm/security language can someone please define to me this; when a normally open (no continuity) door/window SPST contact is in its normal state (no magnet near to activate it) is it considered open? So if I were to say that I need an EOLR on a door contact that is normally open, would that mean that "normal" is when the door is open? Would I then install an EOLR in series or parallel?
Just trying to clear up some confusion for myself. In my field of work as an electrician, NO NC mean just that, unchanged state without energizing or some other force. But the closed/open door contact state is got me second guessing my setup Thank you.
