Description:
With a latch definition, you can achieve that the readers in a reader group are put in a certain reader mode during a certain time zone.
For example, during business hours, you could have the reader of the main entrance set in the mode open. The door is then open during those times and everyone can enter without the use of his or her card. Outside office hours, the reader will automatically fall back into automatic mode at the main entrance (access is granted to valid passes) or Confirm (access is granted after door or administrator confirmation). With a latch definition, you can also let the mode of the readers in a reader group respond to the activeness of a particular input. For example, you can set all doors to be automatically opened in case of a fire alarm so that everyone can go outside.
Setting up a latch is not difficult. It is important that you think carefully about what exactly needs to be done and when or in what circumstances.
