J&D , in Zone Attributes 2 there is "Enable Force Arming" as an attribute to a zone "The user can arm the system/partition with the zone violated."
I don't know if this attribute can be assigned to the "Delay 1" zone (entry), I suppose yes,
Also I asked to Texecom mail and they answered that "the international panel it is automatically a timed set" "As long as the zone is not active once the timer has expired then it will set".
Anyway, if Timed exit works from default or Force arming zone can be set as an attribute, there will be chances for the PIR to work as entry sensor
