Depend on window type (H11, H21, H12, V21, H44), each Logic card supports 1, 2 or 4 inputs.
Each Input
should
be confi gured individually to accept Dry (potential free) or powered contacts.
Make sure all inputs have been confi gured properly before wiring the system, otherwise
system will be damaged.
Please ensure there is no external links between Input terminals and power supply terminals and
wires.
All “2” terminals are internally connected. Using this terminal for common wire for inputs is permitted
ONLY when using the same power source which is supplying the system.
