Doors
There are two types of doors, intelligent and standard. Standard doors (1 to 16)
are handled by the control panel. Keypads or readers 1 to 32 connected to the
Advisor Advanced control panel system databuses are used for simple access
control functions.
Intelligent doors (17 to 64) are controlled by door controllers. Keypads or readers
connected to local databuses of door controllers are named “door controller
readers (DC readers)” and are used for advanced access control functions.
See “Doors” on page 68 for more details.
