If you have been working with this system before, there should be no real mystery.
If you already have 11 hardwired zones, that tells me that you have a hardwired expander, and have at least 5 more unused zones. Run a 2 conductor from the device to the panel location.
If the device provides a normally closed contact connection, then it wires to the security system just like any of your existing hardwired zones. Then you pick the appropriate zone type for that zone (which you have already figured out).
If your system is using resistors, then use the resistor. If you have the resistor requirement turned off; don't.
The only other programming beyond setting the zone type is the you may need to enable the zone in location 203
