Hi there!
The wiring guide is on page 8 of the following manual:
Customer: replied 2 years ago.

was looking a dummies guide ie. PSU to 1+2

Maglocks to ??

Exit Button to ??

Expert:  Pete replied 2 years ago.
Each wiring connection is labelled/identified on page 9.
Does that help?
Expert:  Neil replied 2 years ago.
Do you have a separate power supply for the maglock (in other words one supply for the keypad and one for the lock).
The wiring diagram will depend on this...
Customer: replied 2 years ago.

No, was allowing for the keypad to power the maglocks

Expert:  Pete replied 2 years ago.
Does page 8 and 9 of the manual help, or do you need further information?
Customer: replied 2 years ago.

Using those diagrams doesn't do what I want to achieve

Customer: replied 2 years ago.

I have the keypad being fed by a 12 volt supply, I need the keypad to give a permanent 12 volt supply to the maglocks which will open when the entry code is entered

Expert:  Neil replied 2 years ago.
Hopefully the supply you have is big enough otherwise you can have unpredictable results with the same supply for the keypad and lock...
So the + and - 12v go to 1 (+) and 2...
The + of the maglock should go to the + of the supply as well... Either shared on 1 of the keypad or directly to the supply
Run a wire from 2 (-) to 23 on the keypad then connect the - of the lock to 22
Your lock should now work with the keypad, if you have an exit switch inside the door then wire this directly to 20 and 21
If an emergency exit door then you must have an emergency door release switch on the inside that will cut to the power to the door when pressed, this is need incase keypad failure stops the door being opened...
