CAA480A
Elevator Controller
BASIC OPERATION
The DRM has 16 Floor Selection Inputs (one for each floor control relay of the CAA480A).
A person presenting their card will be allowed to select a floor that they have access to.
Pressing one of the connected elevator floor buttons will only activate the floor control
relay corresponding to the selected floor thus allowing access to the desired floor. The
event will be logged through the controller as an "Access granted valid floor selection"
with the floor that was selected. In the case of a floor being selected that the user does
not have access to, the event "Invalid Floor Selection" will be generated and the user will
need to present their card again and then select another floor. In all cases, once a card is
presented, the user can only select one floor. Once the floor is selected (by pressing the
desired elevator floor button), the user must present their card again in order to select
another floor even if the floor selected was an incorrect one.
MOUNTING THE DRM ON TO THE CAA480A
The DRM connects directly to the CAA480A's DRM Module header plug using a 14-pin
cable. The DRM is designed to be mounted on plastic standoffs (supplied with the DRM)
and fastened to the CAA480A using 4 screws. The DRM comes with 16 floor selection
inputs, one for each floor control relay on the CAA480A. Before connecting the DRM make
sure that DIP switches 7 (DRM ENABLED) and 8 (PWR OFF/ON) are in the "ON" position.
