How to add 2 window contacts to 1 zone

[theshepherdmatt]

Hi all,
I believe it\'s possible to add 2 window contacts to a single zone, I presume that they are just wired together in the terminal block? is there something i need to do via comfigurator 
Many thanks

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

Thanks, 
i\'m a complete novice, I just googled how to wire in a series.
Cheers
