My mind has gone blank and cant seem to grasp the solution.
At the moment there is an existing door entry system in place and on the main door is an electronic lock release which can be opened externally via a fob or internally via handset button within the flats which energises the lock release to gain entry.
Problem is that the door is a little temperamental and cannot be altered, as the lock release isnt secure enough by itself we need something extra.
I am going to fit an electronic door magnet but as the electronic lock release is a normally open contact and proposed door mag is normally closed contact I cant simply tap power from lock release to feed door mag as they work on oppsite principles.
So I think a 12v dc relay is required so in normal state the lock has no power and the door mag has power and when we activate to open the door the lock energises and door mag de energises. I also need to add a push to exit button as the yale is the current way to open the door from inside.
Hope ive explained it clearly.
Anyway, anybody know which type of relay and method of wiring?
Thanks
