Issue
"Door open too long" and "Forced door" alarm masking
Environment
I/NET Resident I/O
Cause
All of the masking, priorities, and message types may be set in the door editor. DOTL and forced door may even be configured as an alarm or message, but if the Resident I/O point is not masked for the door (08DO or 09DO), you won't receive any DOTL or forced door alarms.
Resolution
You can also use this arrangement to your benefit. Maybe you want all transactions to one host but you want the DOTL or forced door to go to another one in a guard station. Maybe you want only those to dial out a pager.
