Overriding Door State - Interlogix CDC4 Installation And Programming Manual

Overriding door state

In addition to being able to define an override schedule for a door, there are
additional methods for overriding a door default state. These methods are:
•
Direct control by management and configuration software (for example,
open/unlock command)
•
Unlock schedule programmed in door settings.
• Scheduled actions (see also "Scheduled actions" section below).
Door state priorities
The priorities for controlling the state of a door are as follows, from highest to
lowest priority:
1. Direct control from management software (for example, ATS8600), or
configuration software, such as Downloader, for example, an operator sends
a door open/unlock command.
2. User access, for example, a user badges their card at a door card reader.
3. Scheduled actions, set using the configuration software.
4. The door programmed unlock schedule, set using configuration software.
Scheduled actions
Up to 100 door schedules can be programmed in CDC4, allowing for very flexible
door locking and unlocking schedules.
Door schedules have an active period (set via a start date and an optional end
date). If no end date is set, then the active period is for the start date only. You
can also specify if the door schedule is active on particular days of the week
(and/or holidays) during the active period.
Door schedules must be configured with a start time for when the start action (for
example, door unlock) will be executed.
Start actions can be either timed or immediate:
•
Timed actions have an action duration that can be configured from 1 second
to 366 days. The door will remain in the state defined by the start action for
the action duration.
If the door state is overridden (for example, by management software or a
user badging a card), then at the conclusion of the overriding state, the door
will revert to the state defined by the start action. At the end of the active
duration, the end action, if defined, will be executed.
If no end action is defined, then the door will revert to its default state.
•
If no action duration is configured, then the start action is immediate. The
door will remain in the state defined by the start action.
