Issue
Door unlock schedule configure for 8:00 AM to 4:00 PM active so doors unlock at 8AM and relock at 4PM.
Occasionally, there is a need to additionally unlock the door from 6:00 PM to 7:00 PM.
Created an exception event on the specific day for 6PM to 7PM but this causes the doors to lock in the morning (8AM to 4PM)
Environment
CyberStation
All CXs, i2s and b3s
Cause
An exception event added to a day overwrites the whole day so on a regular day with event active 8:00 AM to 4:00 PM if an exception event active 6:00 PM to 7:00 PM is added the resultant effective event for the whole day is active at 6PM and inactive at 7PM.
This will cause the door to remain locked until 6PM.
Resolution
The proper way to have the door unlock from 8AM to 4PM and then again from 6PM to 7PM on an exception basis is to add an exception event to the day configured for 8AM to 4PM and 6PM to 7PM. In other words, the exception has to include the events for the whole day as it overrides ALL normal events for the day.
