2 or more window contacts should be wired in series, so that if any window contact is open then the zone will detect as Open
If you do not use End of line resistors then the wiring is simple. If you do use EOL resistors then they should be wired so that the series resistor 2K2 is in series,m and the 4K7 resistor is in parallel wth the combined series contact
