APPLICATION
The S300-DIN-RDR2S module supports up to two doors per unit. It uses standard RS-485
communications and can interface with the following controllers:
CK722
CK721-A
CK721
CK720/CK705
NOTE
Firmware update to RDR2S modules is recommended but optional if no
change to the terminal configuration take place after upgrading to CK721-A
v.3.0. Firmware update to all RDR2S modules is required if changes to the
terminal configuration take place after upgrading to CK721-A v.3.0.
The RDR2S provides the ability to configure supervised 4-state inputs and unsupervised
2-state inputs. When interfacing to a single door, the unused points can be configured as
general purpose input/output (I/O) points, possibly eliminating the need to purchase
additional I/O modules for certain installations.
The RDR2S provides power for card re
aders and door locking hardware.
INSTALLATION
Unpacking the Equipment
Carefully inspect the S300-DIN-RDR2S shipping containers as soon as you receive
them (with the delivery agent present). Some shipping companies want to have an
agent present when a damaged container is opened. If a container is damaged, open
it immediately, inspect the contents, and have the agent make note on the shipping
document. Check the purchase order against the packing slips to ensure the order is
complete. If the contents of a container are damaged in any way, notify the carrier
and your Johnson Controls representative immediately. Report any discrepancies to
your Johnson Controls representative. Save the packing materials for possible return
shipments.
