Combining Window Sensors

I’m wiring up a new house to a pair of six zone alarm panels. The dining room has six windows, each with it’s own sensor. It makes no sense to have each of these as a separate zone so was wondering if I can just wire these six sensors in series at the alarm box and connect as one zone/connection to the panel? Issues? Thanks in advance.

Yes, this is extremely common. Make sure they’re wired in series to work correctly. See: Wiring Your Window and Door Sensors
