How to generate Door Ajar alarm when system is shunting the ajar alarm due to door unlocked by schedule.

Issue

When a door is unlocked by schedule (or timed/permanent unlocked) the Continuum controller by design does not perform door ajar checking until the door re-locks.

At a site a Door is unlocked by schedule during business hours (8-5) but site still wants a door ajar alarm if someone goes thru the door and leaves it ajar.

Resolution

Write a PE program to monitor the door's DoorSwitch and set the DoorAjar flag as needed, care should be taken as to only engage the PE program when the access engine in the controller is shunting the alarm in order to avoid contention.
